Staircase made of profile pipe. A simple staircase made from a profile pipe: do-it-yourself installation. Calculation of the flight of stairs

IN construction stores There are dozens of options for metal stairs, made mainly of steel and aluminum: from aluminum pipes they make lightweight ladders and stepladders, and capital inter-level as well as external structures are made from steel. The cost of a finished two-meter ladder starts from 2 thousand rubles, an inter-level one - from 30,000. Meanwhile, a DIY pipe ladder would cost at least half as much. For her self-made need to have skills welding work and sufficient time.

What kind of stairs can you make with your own hands?

In addition to extension stairs, there are marching stairs (straight and rotary), bolt and spiral. Let's look at the features of each type:

  1. Extension ladders. The simplest among them are the attached ones, which are two parallel supports with crossbars installed between them. Such ladders are usually mobile and light in weight.
  2. Marching stairs. Characteristics of this type:
    • Marching stairs have more complex design and consist of beams fixed at a certain level with steps attached to them.
    • Marching staircase, forming a straight row is called single-level, two rows with a span are called two-level, etc. A flight of stairs made of profile pipe It is most often made by the owners with their own hands.
    • Stringers (beams that fix the steps from below) or bowstrings (beams that hold the ends of the steps) can serve as support for the flight of stairs.

  1. Spiral staircases. Steps in screw structures are attached on one side to the central beam, bending around it from bottom to top, and on the other - to balusters and railings. To make such a staircase, you need a central metal beam, as well as wood or profiles to construct the base of the steps. Such stairs are rarely made independently due to their unpopularity (these designs are very steep and inconvenient).
  2. Bolt stairs. In this case, the steps are attached to the wall using especially strong bolts - bolts. The free ends of the steps are connected to each other by rails and railings. The fundamental feature of such stairs is that their installation requires a strong wall on one side. Making such a staircase yourself is possible, but it does not require metal pipes.

Thus, the most suitable for self-production are marching and extension stairs made of pipe. Below are instructions for making them.

How to make a ladder

Materials

Making an attachment staircase design is not difficult even for those who have never held a welding machine in their hands, since the crossbars can be secured to the frame using bolts. However, welded metal stairs made from pipes are more durable and reliable, and their manufacture requires a minimum of materials, the list of which is presented below:

  • 2 profile pipes with a diameter of 40x40 mm and a length of 2.5 meters;
  • 10 pieces of profile pipe 40x40 mm, 30 cm long;
  • 4 square steel plates with a cross section of 40x40 mm;
  • 20 steel angles;
  • flat surface (table or two chairs with backs);
  • primer for metal;

Sequence of work

How to weld a staircase from a profile pipe? Installation of this type of staircase structure will not take much time. Before you start welding the parts, you need to place them on flat surface. Installation in inconvenient conditions may result in ready product will be skewed and unstable. The sequence of work is as follows:

  1. Lay out two long ones metal supports necessary at a distance of 30 cm from each other (corresponding to the width of the crossbars).
  2. Then make marks, the distance between which should be 25 cm.
  3. Weld according to the marks metal corners. They should be positioned in such a way that they serve additional support crossbars You can do without corners by welding the crossbars directly to the frame.
  4. After this, it is necessary to weld a rectangular frame from two long and two short pieces.

  1. Next, the crossbars should be inserted and welded into the frame, laying them on the corners.

  1. Square rectangles should be welded to the ends of the supports so that moisture and soil do not get inside the product.
  2. After welding is completed, the seams should be cleaned with a grinder or sandpaper.

  1. The resulting structure is primed and painted.

At this point, the ladder made from a profile pipe is ready. All that remains is to dry it. When making a design for home use it would be more expedient to take aluminum profile because it is very light. If necessary, you can increase the length of the stairs from square pipe. This will require large pipes: for example, for a 4-6 meter product you will need a pipe with a cross section of 50x20 mm.

How to make a staircase frame

Materials

Making a staircase to the second floor from a profile pipe is a very common method. Such structures are used inside the house (to connect floors) and outside (for the construction of fire escapes, porches, etc.).

Making a flight of stairs has always been considered the most difficult element of house construction. Even a straight single-flight design requires careful mathematical calculation.

To calculate the parameters of the stairs, you can use special programs or perform the calculation manually.

You should know the following parameters:

  • the optimal width of the stairs is 80-120 cm;
  • the optimal tilt angle is 45 degrees;
  • height between steps - 12-20 cm;
  • step depth 25-40 cm;
  • the number of steps is the quotient of the length of the staircase and the width of the step;
  • the length of the stringer is the root of the sum of the length and height of the staircase squared;
  • the calculated load on the stringers is equal to the sum of the steps multiplied by 1.1 and the sum of the weight of people simultaneously on the stairs multiplied by 1.4;
  • the profile cross-section is calculated using the formula I = 5.2xbxQxL/E (b-step width, Q-calculated load, L-stringer length, E-elasticity index of steel equal to 2100000).
  • railing height - 90 cm (for adults) or 60 cm (if there are children in the house).

The initial dimensions of the staircase are determined by the characteristics of the room: its area, height, as well as the location of the staircase and its design. To build a straight single-flight structure you will need:

  • rectangular metal profile for stringers (length and cross-section depend on the length and height of the stairs and the dimensions of the steps);
  • metal profile for the construction of a frame for steps (defined as the sum of the width of the step and the height of the step, multiplied by the number of steps).

If everyone is present necessary materials and according to the staircase diagram, the construction of the frame is carried out. For this you will need:

  • grinder or hacksaw;
  • welding machine and 3 mm diodes;
  • grinder or sandpaper(grades P100 or L2);
  • primer for metal;
  • building level and corner;
  • cement for preparing concrete;
  • anchor bolts (2-4 pcs);
  • paint for metal surfaces.

Sequence of work

The installation process of the staircase frame is carried out in the following sequence:

  1. First of all, you need to cut the pipes for the stringers.
  2. Then cut the pipes to create the ridge of the frame for the steps.
  3. After this, the stringers are placed in in the right place(it is advisable to concrete or reinforce their lower ends anchor bolts; the upper ends are secured with anchor bolts).
  4. The stringers will serve as a kind of platform, thanks to which the entire structure will be more reliable and stable. When organizing a two-flight staircase, profile gratings are additionally installed to act as spans.
  5. Then sections of metal profile pipes are welded to the platform, forming a ridge-shaped frame of the staircase from a profile pipe for the steps.

  1. All work is carried out strictly in accordance with the drawing.
  2. Each welded one must be located strictly parallel to that located on the second stringer.
  3. During installation, the angle of inclination of each element should be controlled.
  4. Upon completion of welding work, all welds are sanded, and the structure is primed and painted.

This completes the creation of the frame metal stairs completed. As a base for steps can be taken wooden blanks, placed in metal frames or bolted to the base. A simpler option for creating a base for degrees is shown in the photo below.

You will also find detailed video instructions on how to make a metal staircase from pipes useful.

A home craftsman must be able to make a straight extension ladder, which is indispensable in the household. The design must meet the main requirements - safety and reliability. To create a durable staircase, you need to correctly select the components, become familiar with the technology, develop a drawing and perform the assembly. The stages of manufacturing the attached structure are described in the article.

An extension ladder is an indispensable thing in the garden

In a country house or garden, an extension ladder will be needed when performing work at height. Seasonal pruning of fruit and park trees, tinting window frames, harvesting and other events are not complete without gardening tools. Extension ladders are distinguished by their mobility, light weight and simplicity of design. Essentially, these are two support beams fastened together by crossbars.

In hardware stores and construction markets there is a wide range of modifications of ladders made of different materials. Buying a high-quality large-sized model is quite expensive, and the reliability of cheap stairs raises some doubts. Therefore, many home craftsmen often raise the question: “How to make an extension ladder with your own hands?”

The feasibility of independent construction is fully justified, since the scope of use of an extension ladder is quite multifaceted:

  • performing repair and construction work on facades;
  • repair of electrical wiring in a private house;
  • installation of electricity meters, monthly readings;
  • washing window glass on the first and second floors;
  • decoration of the facade of the house;
  • cleaning drainpipes, storm drains;
  • performance minor repairs roofing material.

Despite the significant advantages, a mobile stepladder also has some disadvantages:

  • low load capacity - structures are not designed for loads of more than 200 kg;
  • a narrow support area reduces the stability of the ladder;
  • not very convenient to use due to the lack of railings, steep climb and thin steps.

Metal stairs are considered the most durable and durable. A simple model It’s quite possible to do it yourself. To perform the job, it is advisable to have welding skills.

Design requirements for extension ladders

The main requirement for attached models, as well as for other types of stairs, is safety. When planning the design of the stairs and performing calculations, you should adhere to a number of basic rules:

  1. The maximum length of a ladder of this modification is 5 m. However, this limitation is relevant for wooden models. Metal stairs can be higher due to the strength of the material.
  2. When making stairs, it is advisable to provide for the installation of special attachments: cap hooks, steel pins and rubber pads. These elements improve the stability of the structure.
  3. The optimal step placement step is 30-35 cm, minimum distance- 25 cm.
  4. The span width is at least 40 cm.
  5. Structural parts should not have sharp, raw edges or metal burrs.
  6. In the manufacture of stepladders and retractable modifications of stairs, special locking connections are used that prevent spontaneous opening/closing of the structure.
  7. To make it easier to move large-sized models, wheels are installed on the “support legs”. In this case, it is necessary to provide for the presence of a blocker so that during operation the ladder does not move out from under your feet.

Important! According to safety regulations, the strength characteristics of the ladder must be checked annually. The structure is installed to the wall at an angle of about 70°, and then a weight weighing at least 100-120 kg is placed on the steps one by one.

Types of ladder designs

There are several types of ladders, each of which has design and operational features.

Straight simple stairs with fixed dimensions. A simple model of two support beams and attached steps. It is very easy to make such an extension ladder with your own hands. Folding and sliding models are more functional and reliable.

Folding ladders (stepladders) consist of several parts connected by hinges. The main advantage of the model is its compactness and the ability to be stored in a compact room. Stepladders with a platform are more convenient to use than straight structures. To make a folding ladder with your own hands, aluminum alloys are usually used, which reduces the weight of the stepladder.

Folding models most in demand when arranging attic spaces. The staircase saves space on the lower floor - just pull the bottom step or a special handle and the structure will straighten out completely.

Disadvantages of folding modifications:

  • complexity of design, assembly and installation;
  • the need to use expensive components;
  • low strength of a structure consisting of several elements.

Retractable ladder with height adjustment. Models consist of two or three sections, fasteners, guides, rollers and height clamps. To ensure that the ladder does not fail at the right time, the working mechanisms must be regularly lubricated.

Selecting material for making stairs

Straight stairs today are made primarily of metal, and traditional wooden structures are becoming less popular.

Distinctive features of metal ladders:

  • for self-production, aluminum is usually used, stainless steel or metal alloys;
  • high strength, resistance to moisture and mechanical damage;
  • aluminum does not corrode, but structures made of other metals need to be treated with protective agents;
  • high load capacity;
  • practicality and durability;
  • To make a metal ladder by hand, you will need experience in welding.

A wooden ladder is easy to manufacture, but is demanding in terms of storage and operating conditions. If the air is too dry, the wood will dry out, the material will weaken, and cracks may appear. Under the influence of high humidity, wooden stairs are subject to rot. To reduce the risk of structural destruction, it is necessary to regularly treat wood with protective agents.

Important! Wooden ladders can withstand loads of up to 150 kg.

When conducting electrical installation work often used sliding stairs made of fiberglass - the material protects against electric shock.

Drawings of ladders

Making ladders with your own hands begins with developing a drawing. It is necessary to schematically display the main parameters of the staircase structure:

  • height and width;
  • parameters of the material used (diameter/section of metal, etc.);
  • stair step;
  • fastening type;
  • type of support.

As an example for creating a sketch, existing diagrams from the Internet are suitable.

Required tools and materials

To create a simple metal staircase you will need the following materials:

  • profile pipe - two sections of 2.5 m each, diameter - 4 * 4 cm;
  • sections from a profile pipe with a length equal to the width of the stairs (30-35 cm) - 10 pcs.;
  • square metal plates size 4*4 cm - 4 pcs.;
  • steel corners - 20 pcs.;
  • primer for treating metal surfaces;
  • dye.

The tools you need to have on hand are:

  • a hacksaw or grinder;
  • square;
  • grinding machine or sandpaper;
  • wide, durable table for laying out design parts.

The procedure for assembling an extension ladder

Let's take a step-by-step look at how to make a ladder with your own hands. The assembly diagram is as follows:

  1. Place metal supports on the table. Make sure that the elements are located parallel to each other at a distance of 30 cm (the width of the stairs).
  2. Make marks for installing steps in 25 cm increments.
  3. Weld metal corners along the marks - they will additionally secure the crossbars.
  4. Weld two 30 cm sections to the supports at the bottom and top. The result should be a rectangular frame.
  5. The crossbars are laid sequentially on the corners and welded with a double weld.
  6. Weld metal plates to the ends of the supports above and below. This measure will prevent soil, debris and water from entering the supports.
  7. Clean the weld seams with a grinder.
  8. Prime the stairs and leave the metal until completely dry.
  9. Cover the structure with paint, and after complete drying, apply a second coat of paint.

How to make a wooden ladder with your own hands: expert advice

When creating a straight ladder or stepladder from wood, the following points must be considered:

  1. Better to use for work conifers tree. It is unacceptable to make a staircase out of wooden beams, if they have transverse or longitudinal cracks. Bars with signs of rotting or large knots are rejected.
  2. The choice of the minimum cross-section of the support beams depends on the height of the structure being built.
  3. Everything before assembly wooden parts treated with an antiseptic.
  4. Structural elements are fastened together in one of the following ways:
    • overhead method - the steps are fixed to the supports using nails and self-tapping screws; this option is considered the simplest, but not reliable enough;
    • insertion of crossbars - steps are installed in samples prepared in advance in support beams;
    • tenon joint - grooves are made in the bowstrings, and protrusions are made at the edges of the crossbars; fixation can be performed at an angle.


Advice. Tenon connection V wooden structures most durable. You can prepare the socket and tenon using a chisel, mallet or electric drill in a stand.

Safety precautions when working on a ladder

Attachable models are not self-supporting, so knowing basic safety precautions will help prevent falls and injury.

  1. Long-term work at a height of more than 1.5 m must be carried out with a safety belt.
  2. The ladder must not be placed on boxes, tables or other objects to increase its height. It is better to “join” two separate ladders with metal clamps. Before work, the structure must be checked with a load of 150 kg.
  3. The safest installation angle is 60°. When placing the ladder at 75° or higher, it is advisable to secure it at the top.
  4. To prevent slipping when climbing, the steps must be equipped with rubber pads.

On the ladder it is prohibited:

  • lift heavy objects;
  • tension electrical wires;
  • use dimensional welding machines and electrical equipment;
  • move without holding onto the stairs;
  • More than 1 person can climb at the same time.

Compliance with the technology of design and operation of an extension ladder is the key to safe execution various works on high.

Making an extension ladder from metal profiles: video

What is a staircase made from a profile pipe, what qualities does it have, what are its advantages and how to make it yourself? When constructing them, the most different designs, where the profile pillar serves as the base. Welding technologies and metal processing methods of the present time make it possible to produce hardware at a new level, which is characterized by increased quality and reliability. Professional welders and blacksmiths hone their skills, producing impeccably crafted metal products that can surprise even those with an aesthetic taste.



These skills are good for building outdoor stairs. For interior spaces cottages, dachas and other multi-storey premises are suitable interfloor stairs from a profile pipe that can be made with my own hands. You can also make a spiral staircase from this material. Although making such a design is a process that requires time and labor, these products are strong and durable and are worth the effort. Examples of such structures can be seen in the photo.

According to classification they are divided into different groups, but we are interested in indoor ones that you can do yourself. Most often, pipes with a cross section of 40 by 60 are used (see photo). When using smaller sizes, the design is considered unreliable, because a profile of this size is not strong enough.






How to build a staircase with your own hands

The most you need is the ability to work with welding, and, of course, the presence of a profile and a corner. It's not that difficult to build it on our own. By the way, if you do not have welding skills, then representatives of this profession can be found everywhere and always.

Here specific example such work. I think many people are wondering how to make the design that is being created take up as much space as possible. less space in our house. With all this, not many people like screw designs or almost vertical ones.

First you need to make a frame that will hold the structure. You need to prepare the basic elements: pipes, angles, and a welding machine.

Marching structures

  1. Corners are welded to the side edges of the frame, welded from pipes.
  2. Steps are attached to these corners. They are welded from sheet iron.
  3. Then the burrs are removed using a file.
  4. Next, before painting, the structure is primed to prevent rust.

Screw designs

To create a frame spiral staircase, take required length a pipe and a similar one, but of a larger diameter, for steps.

The pipe for the steps is cut into sleeves approximately 220 mm long.

  1. Before starting work, we need to know how many elements we need. Divide the height of the room in which ours will be located homemade design, for the estimated length of the space between the steps, that is, 220 mm.
  2. Then you need to cut the gasket and console from steel. We weld the gasket to the console, then weld the resulting elements to parts of the pipe (100 mm in diameter).
  3. We install the steps onto the gasket using self-tapping screws. The tight fit of the sleeves located on the pipe must be maximum; distortions and backlashes are not acceptable. If gaps appear due to an inaccurate diameter, we make sealing rings.
  4. Then you need to mark and assemble the steps. They need to overlap about five centimeters. To do this, the length of the circle should be less than the wider side of the steps.
  5. Now all that remains is to put all the pieces together.

As you can see, making a staircase from a profile pipe with your own hands is not so difficult, it’s enough simple equipment, skills home handyman and a little bit of life savvy.

Staircase made of profile pipe - 2 of the most best options for home and garden

Square or rectangular hollow metal pipes have long become almost the main material for the construction of lungs frame structures in private construction. The familiar do-it-yourself extension ladder made from a profile pipe is found in almost every dacha.

To weld it from the pieces of material left after the construction of a fence or gazebo, you don’t need a lot of intelligence, weld the crossbars between the guides and use it. Today I will talk about the calculation and assembly of more complex marching and screw structures from the same profile pipe.

What you need to know when calculating any staircase

The calculation of a staircase made from a profile pipe is not much different from the calculation of similar structures made of wood or concrete. Such calculations cannot be called too complex, the instructions are standard, but you should not neglect the stage of drawing up a drawing or at least sketching out a sketch, laying out all the dimensions and angles.

Calculation of the marching structure

Marching structures are rectilinear structures that do not have smooth bends or turns. There are also stairs with an intermediate turning platform, and if all the flights joining them are straight, then such structures also belong to the flight.

  • You should start by measuring the height of the future flight of stairs. This is the easiest way to do it. The flight height refers to the distance between the floor of the lower and upper floors. In other words, you need to add the thickness of the interfloor ceiling to the height of the ceilings;
  • In order to make it comfortable to walk on your stairs, you need to clearly calculate the dimensions of the tread and riser. The tread refers to the platform on which we place our feet, and the riser is the vertical distance between the treads. In both cases there is a comfortable operating range, so for the tread it lies in the range of 200 - 400 mm, and for the riser 150 - 200 mm;

  • But it is equally important to maintain the correct relationship between the selected values. There are also a couple of formulas to calculate this ratio. I prefer A + B = 470 mm (“A” is the height of the riser, “B” is the size of the tread). In addition to it, there is another formula 2A + B = 640 mm, to be precise, not exactly 640 mm, but from 600 mm to 640 mm;
  • The minimum width of a stationary home span starts from approximately 800 mm;
  • Once you have calculated the appropriate tread and riser sizes for you, you can already calculate the number of steps (the height of the span divided by the height of the riser) and the horizontal distance from the beginning to the end of the span (the number of steps multiplied by the size of the tread);

With a ceiling height of more than 2.5 m, the horizontal distance (along the floor) from the beginning to the end of the flight starts at approximately 5 m. For small rooms it makes sense to build a turntable with a rotation of 90º or 180º.

  • Now we just have to find out the most important thing. What will be the size of the future stringer made from a profile pipe? The Pythagorean theorem will help us here. For those who have forgotten a little, I remind you that the square of the hypotenuse must be equal to the sum of the squares of the legs (a² + b² = c²). We have two legs, this is the flight height and the horizontal size, all that remains is to calculate the hypotenuse, which is actually our stringer made of a profile pipe;
  • There is one more point that must be taken into account when calculating: the angle of inclination of the march. So, according to SNiP, for stairs in residential premises this angle ranges from 23º to 37º. If it’s less, then it’s already a ramp, and if it’s more, then you’ll get tired of climbing those steps.

So that you fool yourself less with all the calculations, in the table below I have collected the most popular parameters of direct marching structures:

Step dimensions March angular inclination

(given in degreesº)

Step width Riser height
400 mm 100 mm 14
380 mm 110 mm 16
360 mm 120 mm 18
340 mm 130 mm 21
320 mm 140 mm 23
300 mm 150 mm 26
280 mm 160 mm 29
260 mm 170 mm 33
240 mm 180 mm 37
220 mm 190 mm 40
200 mm 200 mm 45

When calculating, it is extremely rare to obtain integer, convenient numbers. So, it is better to round the data up, so it will be easier for you to work in practice.
And the error that remains is compensated by the height of the first stage. Believe me, if it is a little smaller, no one will even notice.

Calculation of a spiral staircase

The choice in favor of a spiral staircase is most often made due to a lack of space, although in some cases this decision is caused by the designer’s original idea. The price of such work for professionals is much higher, so it makes sense to calculate and assemble the supporting frame of the staircase from a profile pipe with your own hands. Moreover, this is not much more difficult than working with a straight march.

As in any business, there are 2 ways, for the lazy and for the persistent. If you don’t want to bother with calculations, then you can use a calculator for calculating spiral staircases, of which there are now plenty on the Internet. And for those who are persistent, I will further tell you how this is done manually.

First, let's look at the parameters and notation. By the way, the same notations are used in most electronic calculators.

  • “H” is the vertical height of the structure. That is, the height of the ceiling, plus the interfloor ceiling;
  • “H¹” is the interturn distance. This should be understood as the distance from the step you are standing on to the step above you. Naturally, this parameter should not be less than average human height, about 185 cm;
  • “h” is the height of the tread, this is what we called a riser in the staircase;
  • “h¹” - tread size or step depth, as you like;
  • "R" - outer radius along the edge;
  • “R¹” is the working radius or the one along which a person will climb the stairs;
  • “r” is the radius of the central support.

  • Along the working radius line, the depth of the tread should be in a range that is comfortable for a person, it is the same as in the case of linear marches of 200 - 400 mm;
  • The width of the tread next to the central support must be at least 100 mm;
  • The minimum span width is 1 m, but if you are not going to make railings, then this value increases to at least one and a half meters;
  • In spiral staircases, the risers are usually left open, this is much more convenient. Compared to marching structures, a slightly larger variation in riser heights of 120 – 220 mm is allowed here.

As in the case of marching structures, you need to start with preliminary measurements. This includes the outer radius of the structure, the height of the staircase and where you plan the entry point and exit point, this is called the angle of twist of the structure. After this, you can start making calculations.

For example, I took fictitious values, you will naturally substitute your own. Let the outer radius “R” = 1000 mm, the height of the structure “H” = 3000 mm, the twist angle ω = 360º, that is, the entrance and exit are located above each other.

With this data we can find the working length of the march “L”, that is, the size of the stairs along the working radius line. It is believed that the working radius is about 2/3 of the maximum. Starting formula L=2πR¹.

Now we find out the number of steps:

  • Let the tread size “h¹” be 250 mm, the basic formula is n=L/h¹;
  • Therefore, 4190/250=16.79. The number of steps cannot be fractional, so we round up to 17, in addition, our top step coincides with the floor level, as a result we get 16 pure steps.

If we take as a minimum (100 mm) the size of the tread at the central pillar, then we can fully calculate the dimensions of the entire tread, only for this we will also need to find out the length of the structure along the outer radius “Lext”.

Lext = 2πR = (2*3.14*1000) = 6280 mm. Now we substitute everything into the starting formula.

h¹ = (7536/17) =369 mm

The height of the riser here is calculated in exactly the same way as in the flight span. The total height “H” is divided by the number of steps “n”, resulting in:

h = (H/n) = (3000/17) = 176 mm.

Correction of the ratio of steps is also permissible here and is done according to the same formula as for a linear march, only the designations change slightly.

2h + h¹ = 600 ... 650 mm. After correction we get a riser height of 190 mm.

But that is not all. We still need to calculate the dimensions of the upper exit platform. As you remember, our twist angle is 360º, the height of the riser in our case is 190 mm, the total height is 3000 mm.

In other words, by going up 4 steps, we will lose the height of 760 mm. If we take into account the thickness of the ceiling, then we have about 2m left. Therefore, the width of the upper platform should not exceed the width of 4 treads, otherwise tall people will cling to their heads.

Both when designing linear flights and when calculating a spiral staircase, try to ensure that the number of steps is always odd. The fact is that it is subconsciously more convenient for a person to start and finish a movement with one leg.

Assembly of structures

If you can handle the calculations and drawing up a sketch, marking the pipes for the future staircase will not be difficult for you. Therefore, we will go straight to the question of how to weld a staircase from a profile pipe.

Theoretically, of course, such a structure can be assembled using studs and bolts, but, not counting the complications in the calculations, the time and effort required to assemble this staircase will take at least 3 times more.
Plus, this option is not considered absolutely reliable, since the bolts tend to loosen during operation. Therefore, I do not advise you to get involved with such models.

Assembling the march flight

Linear marching structures can be of two types: this is a staircase based on a powerful, flat profile pipe and various designs with broken stringers.

Designing and welding the first option with a solid, straight pipe is much simpler and takes much less time, but the price of such a structure is slightly higher. This is due to the fact that as a base you will have to buy a square profile with minimum cross-section 100x100 mm, although I recommend taking from 150x150 mm. Such stairs are much more reliable and look better.

In addition, the platforms on which the treads will be attached should not be more than half narrower than these same treads. Therefore, you will have to weld additional metal sheets thickness from 3 to 4 mm, and such an amount of thick, high-quality metal inevitably leads to an increase in the cost of the project.

As you understand, on a flat inclined pipe, the horizontal treads will need to be secured somehow. Consequently, the sites will have to be welded on. You can do them in two ways.

  1. After we have calculated the angle of inclination of the pipe and marked the places where the steps are attached, pre-cut metal sheets are welded horizontally to the base along the entire width of the profile pipe, and subsequently they will be screwed onto them wooden treads. But naturally, one horizontal seam cannot withstand such a load, so supports will have to be welded between the sheet and the pipe. These can be metal plates, pieces of reinforcement or profile pipes of a smaller cross-section. As you can see, it’s nothing complicated, but to be honest, this option doesn’t look very nice;
  2. I like the second option better, it is simpler and looks more aesthetically pleasing.. The supports for the platforms are cut from the base profile pipe and sheets for the treads are welded onto them. To do this, mark a cut on it at the calculated angle, take a grinder and. From the side, such a cut will look like a triangle, and from the front side it has the shape of the letter “P”. Further along our cut we weld this support to the base pipe. The diagram shows both options.

Since the entire structure will actually be based on one pipe, the weight there will be serious and there will be colossal point pressure at the junction of the profile pipe with the floor.

In order to distribute it evenly over a larger area and insure against the lateral tipping of the ladder, you need to go to the base of the pipe and the fixation point to interfloor covering weld metal plates with a thickness of 5 mm. The dimensions of such plates should be slightly more area steps.

Now let's look at assembling a staircase based on broken version stringer. In addition to cost, such designs are good for their low weight. After all, they use pipes of a much smaller cross-section.

It is believed that optimal size is 40x60 mm. More is possible, less is not advisable.

Here, as in the case of a straight stringer, you can cook it in two ways:

  1. According to the first method, the profile pipe is cut into separate sectors corresponding to the dimensions of the treads and risers, plus a margin for the thickness of the pipe. After which all these pieces are welded together into a finished string. In theory it sounds simple, but in practice there is too much welding work and it is not a fact that you will be able to weld everything smoothly everywhere;
  2. According to the second option, everything turns out much more elegant and faster. The idea is to use a grinder to cut out sectors in the form of isosceles triangles from a straight pipe, leaving only one wall intact. After this, we bend the pipe and weld the connection. I have shown what it looks like in the diagram.

As for the plates for support points, for a profile pipe with a cross-section of 40x60 mm it is enough to weld squares of approximately 200x200 mm and secure them to 4 anchors. Although, if possible, of course, it is better to connect two or more broken stringers on a single monolithic plate.

Assembly of the screw structure

Installation here begins with the installation of a central supporting round and preferably thick-walled pipe. The load on it will be serious and here the savings may come back to bite. As I already said, the pipe cross-section starts from 100 mm, this is the minimum width of the tread at the base.

Naturally, the pipe itself from below must be based on a thick, reliable platform. If you are installing a ladder at the construction stage, then in order not to spend money on an expensive thick iron sheet, you can weld a cross from the same profile pipes at the bottom. Then wall it all up in a screed.

The supports themselves for the treads can be made of two types. What is it in bearing capacity, and in terms of aesthetic characteristics they have little to show for it. Here it all depends on what section of the profile pipe is at hand:

  1. If you have a thin tube 20x20 mm or 30x30 mm, then it is better to weld the frame around the perimeter of the tread, in a closed loop. In order not to measure each arc separately, you should immediately make a pattern from wooden blocks stuffed onto a sheet of chipboard. With such a device, all you have to do is insert the cut tubes into your pattern and “tack” them by welding;

  1. There is less hassle with the second option. But it uses profile pipes with a minimum cross-section of 40x60 mm. There is no need to construct any patterns here. Simply cut the pipe sections along the working radius of the stairs. At the outer end, in the shape of the letter “T”, weld a piece of the same tube, slightly smaller than the width of the tread, and at the end weld this entire structure to the supporting pipe.

In both the first and second cases, one fixation point on the support is not enough for the step. Therefore, I recommend welding additional support under the step frame. There is no guarantee that you will be able to weld everything firmly and efficiently, and with a support the reliability of the step increases significantly.

Finishing work

Most often, the frame of a staircase from a profile pipe is lined natural wood. According to my observations, it is much cheaper, beautiful and reliable.

When selecting a board for treading, the most important thing is strength, so its thickness should be at least 40 mm. The thickness of the facing for risers and side string, if required, does not have of great importance, since these parts of the staircase carry only an aesthetic load.

Don't forget that you are dealing with metal, and as you know, it can rust. I don't think you're going to spend a fortune on a homemade stainless steel ladder. Therefore, after assembly, you first need to clean it with a file or better than a grinder all welds. After this, degrease or prime the structure and finally apply 2 - 3 layers of good paint.

Many people recommend powder coating the metal. So, such things as powder painting or nickel plating of metal can be done exclusively in a factory environment using professional equipment. At home, you can only paint or varnish the stairs.

Conclusion

For self-production, a staircase frame made from a profile pipe is ideal. It's much easier than building stairs from wood, plus durability metal structure much higher.

Any modern construction project involves arrangement flights of stairs connecting floors of a residential building. At the same time, for the manufacture of the frame flight of stairs The most technologically advanced materials are used, which include profile pipes.

In this article you will learn how to make a staircase from a profile pipe with your own hands, and you will also be able to familiarize yourself with all the advantages of the described design.

Interfloor staircase structures made of pipes look great in modern interiors country houses, office premises and other buildings. In addition, for the manufacture of stairs of this class, today it is widely used metallic profile with a cross section of 60x40 mm, the size of which is considered the most optimal.

This choice is explained by the fact that smaller sizes reduce the strength of the structure, and larger profiles make it too bulky and heavy.

Advantages of profile structures

Choosing a profile pipe for arranging a flight of stairs will provide you with a number of unconditional advantages:

  • high strength and reliability of structures of this class;
  • good performance and durability;
  • the use of well-established technologies that significantly reduce time and labor costs;
  • the ability to vary the configuration of staircases using modern elements decor;
  • quite reasonable price.

Note!

The technologies used in the production of the profile allow it to be painted in any color (by powder coating method). At the same time, you can choose a color that optimally matches the interior of the room you are furnishing.

Note that silver, gold and black colors are currently considered the most fashionable.

Also note that this design provides the ability to prepare a straight march, allowing you to change the direction of its installation by 90 and 180 degrees.

Organization of work

When installing the base (frame) of a staircase structure, profile pipes are installed and fixed on the platform in pairs, after which steps from the material chosen by the developer are mounted to them.

The procedure for preparing the staircase frame may look like this:

  • preliminary marking and cutting of profile blanks,
  • installation of frames for steps,
  • production of steps,
  • their installation and welding.

Note!

This procedure for organizing work requires the mandatory use of welding equipment, as well as possession of skills in handling it.

Manufacturing procedure


As an example, we invite you to consider the technique of making stairs with steps made of wood and a frame made of profile pipe. The frame base of this design is a profile pipe with a diameter of 60 mm in combination with a corner with a standard size of 40x40 mm.

The process of arranging such a structure includes the following operations:

  1. First of all, the required number of steps is calculated, as well as their main dimensions (height and width).
  2. After this, you can proceed to pouring a concrete platform, which acts as the base of the entire structure and provides the required angle of inclination. The level of this platform is the zero level on which the first step of the staircase will be placed.
  3. Immediately after this, you can proceed to the installation of a profile pipe, which, on one side, is welded to the tabs in the platform, and on the other, attached to anchors tightly fixed in the wall.
  4. After this, metal corners are welded to the pipe, all dimensions of which must be maintained with the specified accuracy.
  5. Upon completion of the main work, railings (railings), which can be made of either wood or metal, are mounted on the side of the staircase frame.

Design Features


Note that by installing railings on the side of load-bearing frame you will be able to increase the working width of the flight of stairs. It should also be taken into account that between ready-made design and the wall must leave a passage sufficient not to interfere with the current repair work. To avoid vibrations that sometimes occur when moving along stairs, it is recommended to limit the length of the racks in its spans.

In addition, to make a staircase from profile pipes with your own hands, you will definitely need auxiliary materials, among which the most commonly used are glass, wood, stone and even ceramics. The use of any of these materials not only increases the operational advantages of any staircase structure, but also provides it with a completely modern and attractive appearance.

Note!
Structures of this class are used not only as staircases in multi-story buildings, but also often form the basis of the building’s porch.
