Staircase from profile pipe(not round) is durable and has good wear resistance. Unlike wooden stairs, metal is more durable, although it may be heavier. The profile pipes themselves are already heavy, so you need to monitor the weight of the ladder as you work and try not to make it heavier, or better yet, reduce its weight. You can do this using the tips that can be found in this article.

Before starting work, it is necessary to make measurements, according to which the staircase will be built in the future.

What you need to know before starting:

1. Dimensions of the staircase opening;
2. Calculation required quantity material;
3. Turning the stairs;
4. Number of steps.

A staircase opening is a free space in the ceiling between the first and second floors. The very first thing you need to do is calculate the dimensions of this opening.

The amount of material is determined after all measurements, based on an already drawn up drawing.

Rotating the stairs is necessary when the dimensions or other features of the room do not allow the stairs to be placed straight, without bending at an angle.

It is also important to determine the number of steps on the future staircase. It is convenient to do this, knowing that the length of one step should be approximately 30 centimeters, the width from 90 to 125, and the distance between steps in height that is comfortable for a person is 15 centimeters. In special cases, the width of the steps can reach 180 centimeters, but such huge stairs will require additional fastening.

Also, when making calculations, remember that the average human step is 60 - 64 centimeters.

Installation of stairs from a profile pipe: drawing and necessary tools

Without a good drawing you will not be able to make a quality staircase. If you have never dealt with circuits before, then it is better to seek help from a professional.

What is taken into account when drawing up a drawing:

1. Size of staircase opening;
2. Rotation, width and height of the stairs;
3. Number of steps.

You can also add future artistic decoration stairs if you plan to embellish it a little.

Calculating the inclination of the staircase steps will allow you to design a convenient and safe structure. Our information on how to choose the angle of inclination of the steps next material: .

After you have made the drawing and bought all the materials, you need to prepare everything necessary tools that will be needed during the work process.

Tools that will be useful when creating a staircase:

1. Welding and electrodes for it;
2. Grinder saw and discs for working with metal;
3. Hammer, drills;
4. Hammer.

In order not to get confused in the process of creating a staircase large quantities different parts, we advise you to number them.

Preparing a staircase frame from a profile pipe: tips

The frame is the basis of the future staircase, so it is necessary to think it through to the end, and then weld it with high quality.

Remember that when making a frame, welding will be required in any case. And that means the ability to handle it. If you do not have such skills, then you will have to resort to the help of a welding specialist.

The frame base is most often a pipe with a diameter of about 60 millimeters.

Frame manufacturing stages:

1. Calculate the number of steps, their height and width;
2. Proceed with the installation of the profile pipe. It will be mounted on wall anchors, which must first be installed. Additionally, the ladder must be secured on the other side using bookmarks.
3. Weld the corners to the pipe. Make sure that their measurements exactly coincide with those specified in the drawing, otherwise the final result will be of poor quality, and the staircase will be crooked and unsafe.
4. If necessary, railings can also be installed towards the end of the work.

How to weld a staircase from a profile pipe: further finishing

After you have finished making the staircase frame, you need to move on to its further finishing.

What to do after installing the frame:

1. Make steps;
2. Install railings;
3. If necessary, decorate the stairs.

Please note that a staircase made from a profile pipe is a heavy structure in itself. Therefore, you can lighten the weight a little by making the steps not from heavy metal, but from light wood.

With the proper approach, the combination of a metal frame and wooden steps will create an additional high cost effect.

Railings can also be made of wood, but do not forget that the wood must be of high quality. As a rule, oak, beech or ash are used in the manufacture of stairs.

You can decorate the stairs at the final stage. For example, if you choose the option with wooden railings, then you can resort to artistic carving or burning.

Staircase to the second floor from a profile pipe: advantages and disadvantages

After you have become familiar with the process from a profile pipe, it is worth thinking about the advantages and disadvantages of such a design.

Advantages of stairs made of profile pipe:

1. Good strength and wear resistance;
2. Long service life;
3. Relatively fast production time;
4. You can create a staircase from a profile pipe alone, without the help of craftsmen;
5. Possibility to create a staircase of any shape;
6. Price for necessary materials not tall.

As you can see, such a staircase really has a lot of advantages. Its service life is noticeably longer than that of wood, and it is not as heavy as stone. However, there are also disadvantages.

Disadvantages of stairs made of profile pipes:

1. The metal frame weighs quite a lot, especially if the staircase is large. Because of this, when finishing the stairs it is necessary to use materials such as wood and plastic.
2. In order to create such a staircase, you need skills and experience working with a welding machine.

Do not forget that the stairs must be periodically treated with an anti-corrosion coating.

How to install a staircase from a profile pipe with your own hands (video)

A staircase made from a profile pipe is heavy and requires additional periodic processing. But the price for its production is noticeably lower than for other types of stairs, and its service life is longer. Properly made homemade structures will last a long time.

Reliable staircase made of profile pipe (photos of structures)

Stairs made on a metal frame are considered the strongest and most durable. In addition, the use of metal as the basis of the structure makes it possible to create unique compositions with incredible turns, large spans and other non-standard design solutions. Therefore, such a staircase can fit into any interior. We will tell you about the advantages metal structures, varieties of stairs made of profile pipes and provide instructions for the manufacture and installation of the structure.

Advantages and Disadvantages

A staircase frame made from a profile pipe has many advantages over structures made from other materials:

• high strength;
• long service life;
• speed of manufacturing a staircase base from a profile pipe;
• the ability to implement any form of structure by using different fastening elements;
• low cost of building materials.

However, metal structures have several disadvantages:

• Due to the significant mass of the frame, lighter and less durable materials such as wood, plastic and glass have to be used as the remaining elements of the staircase.
• For the production of strong and beautiful design All basic connections must be made using welding machine, that is, experience with this equipment is required.

Species

In addition to the usual attached metal products, there are marching, bolt and spiral staircases. Let's look at each type in more detail:

• An extension ladder is the most simple design, which includes two parallel supports with steps perpendicularly installed between them.
• Marching staircases differ more complex design, which involves installing steps on beams installed at a certain angle. This type of profile pipe product is mainly made by the owners of private houses. The supporting elements of the structure can be bowstrings or stringers.
• Spiral staircases. In this case, the steps have the shape of a triangle or a sector of a circle. On one side they are attached to the central support beam, and on the other – connected by railings. Such a structure is rarely made with one’s own hands. This is due not only to the inconvenience of using a steep design, but also to the complexity of its manufacture.
• Bolt stairs. Here the steps are attached using powerful bolts (bolts) directly to the wall. On the opposite side, the ends are connected by balusters and railings. To install such a structure, a strong wall is required. If this is not the case, then you should pay attention to other options for staircase structures.

Thus, the most suitable for self-made are attached and marching structures made of profile pipes. Let's find out how to make these devices with your own hands.

Gallery: Types of stairs made of profile pipes

The structure can only be installed if there is a strong wall. The spiral staircase is difficult to manufacture, but takes up little space. The flight staircase can be installed both inside and outside the house. An extension staircase made from a profile pipe is highly durable and easy to manufacture.

Design calculation

1. The number of steps is determined as the ratio of the height of the future staircase to the height of the riser.
2. The length of the stringer is calculated in accordance with the Pythagorean theorem (the square of the diagonal is equal to the sum of the squares of the legs, that is, the vertical and horizontal projections of the future structure).
3. The load on the support beams can be calculated using the formula: G=1.1*mс+1.4*ml, where G is the maximum load on the stringer, mс is the mass of the steps; ml is the mass of all people who can be on the stairs at the same time.
4. Section metal profile determined by the formula: S=5.2*a*G*L/E, where S is the profile section; a – step width; L – stringer length; E – elastic modulus of the material (for steel E=2,000,000 kgf/cm2).
5. The width of the stairs should be from 80 to 120 cm.
6. The optimal angle of inclination of the structure is 45°.
7. The maximum height of the steps is 20 cm, the minimum is 12 cm. Optimal depth treads – 30 cm.
8. The height of the handrails for adults should be 95 cm, and for children - 60 cm.

Required materials and tools

For self-production ladder from a profile pipe you will need:

• Two steel pipes square section with sides of 40 mm. Do not use profiles longer than 2.5 m as racks, as this will reduce the strength of the structure.
• Sections of profile pipe about 30 cm long. If the staircase is small, then the length of the rungs can be reduced. The number of elements is selected depending on the length of the future structure with the calculation that the distance between steps should be 20 – 25 cm.
• Metal corners (two for each crossbar).
• Square plates with an area of ​​160 sq. mm.
• Measuring tape and marker.
• Corner grinder with a metal disc.
• Sandpaper.
• Primer for metal surfaces.
• Varnish or paint for metal.
• Profile for creating stringers;
• Profile for constructing a frame for steps;
• Blanks for steps (you can make it yourself from wooden planks or purchase finished product);
• Self-tapping screws for metal;
• Grinder with a disc for cutting metal;
• Screwdriver;
• Welding machine;
• Sandpaper;
• Construction level and metal corner;
• Concrete solution;
• Powerful anchor bolts;
• Primer and paint for metal surfaces.

Work order

The length of the crossbars must correspond to the estimated width of the stairs

The procedure is as follows:

1. Place on a flat floor metal supports. We place them strictly parallel to each other at a distance of 0.3 meters.
2. We make marks on the racks in accordance with the selected step location. In this case, the extreme marks should be at a distance of 15 – 20 cm from the ends of the supports.
3. In the marked places, perpendicular to the legs of the stairs, we weld corners that will serve as supports for the rungs.
4. We take two pre-prepared sections of pipe 30 cm long and weld them to the corners, one being grabbed at the top and the other at the bottom of the future staircase. The result is a rectangular frame.
5. Similarly, we fasten the remaining crossbars along the entire length of the structure.
6. To prevent moisture from getting inside the product, we weld plates to the ends of the stairs.
7. All metal connections carefully clean it with a grinder and sandpaper so that there are no sharp corners.
8. Apply a layer of primer to the product, followed by varnish or paint.

Helpful Hint: When the paint is dry, put rubber caps on the legs. This will increase the grip of the ladder on the surface.

Installation

After installing the support beams, the comb-shaped frame is installed

The sequence of constructing a single-flight staircase on a metal frame is as follows:

1. In accordance with the calculated data, we cut pipes for the support beams.
2. We install the support beams in a pre-selected location. We fasten them below and above anchor bolts. It is advisable to concrete the base load-bearing structure. The beams must be positioned strictly parallel to each other.
3. We take the profiles for the frame for the steps and cut them into segments to create a ridge.
4. We weld the pipe sections to the support beams, forming a comb-shaped frame for the steps. When installing each component, it is necessary to control the angle of inclination using building level. Maintain parallelism of structural elements.
5. After execution welding work clean all seams and sharp corners sandpaper.
6. We cover the staircase frame with primer and paint.
7. After the paint has completely dried, we attach the blanks for the steps to the stringers. To do this, we use metal screws and a screwdriver.

On last stage wooden or plastic steps are attached to the stringers

This concludes the process of installing a single-flight staircase on a profile pipe frame.

If you have basic construction skills, then assembling and installing a high-quality staircase from a profile pipe will not be an impossible task for you. And by adhering to the above rules and recommendations, you can build a strong and durable structure.

In those structures where high reliability and durability are required, the elements are made of metal parts.

A DIY staircase made from a profile pipe, made at home, is no exception.

Main types of stairs

A stepladder is a ladder that can stand on its own using any suitable support (a wall, for example).

The stepladder can be one-sided or two-sided. The structure has a frame to which the steps are attached, and the additional elements that the stepladder is equipped with are handrails and legs.

The height of such a structure made from a profile pipe is calculated by determining the interval between the floor and the last step. The calculation is made based on an interval of 20-25 cm. Due to the presence of various functional features a stepladder can be:

• Classical;
• Universal;
• Transformer.

Designs belonging to the universal type combine the functionality of a regular ladder and stepladder.

Can be folding or telescopic. The presented stepladder has a frame consisting of several sections, with each section consisting of 5-7 steps.

Telescopic structures differ in that their sections can be pulled out gradually. They are fixed using special latches or hooks.

The transformable stepladder can work in several positions. Such products made from profile pipes are very compact, lightweight and can easily fit even in the trunk of a car.

The frame of staircase products is assembled using metal profile pipes that serve as load-bearing posts; the steps can be made of wood or a material less durable than the frame.

All connections of the structure made of profile pipes are connected to each other using bolted connections.

This allows, if necessary, to make quick replacement any damaged item. Some stepladders are not dismountable - welding is used to create them.

It is worth noting that the most common and practical material to create the structures described, it is an aluminum or duralumin alloy. The finished product will have the following advantages:

• ease;
• reliability;
• ease of use.

Tools and materials needed for work

To create a stepladder with your own hands, preference should be given to aluminum or metal profile pipes. Such a structure can subsequently be easily transported even on public transport. In addition, this metal is resistant to the harmful effects of corrosion processes and other negative environmental factors.

The profile does not need to be additionally primed or painted, and the service life of the product will depend only on the quality of the assembly. When assembling such a structure, you cannot do without:

• roulette;
• square;
• a simple pencil;
• hacksaws for metal;
• Bulgarians;
• drills;
• screwdrivers;
• hammer;
• metal drills;
• bolts and nuts;
• welding machine.

In addition, you will need such consumables, How:

• belts or chains;
• several rubber heels for the legs;
• metal glue or liquid nails;
• metal sheet from which steps and connectors will be cut;
• metal or aluminum profile pipe.

It is necessary to clarify that it has high electrical conductivity and the finished product is prohibited from being used for repairing high-voltage lines.

However, in everyday life such a need does not occur very often. Aluminum conducts heat well, and outdoors it heats up several times faster than metal.

So, for example, if such a stepladder is left in the sun for several hours in the summer, it will most likely become very hot, which will complicate the work.

A stepladder made from profile pipes is easy to manufacture, and the material is publicly available and has a high margin of safety. A stepladder made from a metal profile pipe requires painting to protect it from corrosion.

Manufacturing procedure

To create a stepladder from profile pipes, it is recommended to follow the following sequence of actions:

1. Prepare metal aluminum or steel pipe and cut 4 pieces of equal length from it.
2. If the pipe is made of metal, then especially large rust should be removed from its surface using a grinder or drill with a special attachment.
3. Securely secure the pipe workpiece in a vice and polish it to a shine with sandpaper or using special means to remove rust.
4. Cut steps with the same length from pre-prepared metal sheets. If necessary, rust deposits are also removed from them.
5. The frame begins to form by welding the steps. If you don’t have a welding machine, you can use angle bolts and nuts.
6. Plugs are welded on top and bottom of the pipe, or rubber tips are put on.
7. Crossbars are welded to the two remaining pipes in their lower and upper parts, the distance from which to the end of the pipe should be 10-15 cm.
8. The frame made of supporting profile pipes is positioned horizontally and a number of holes are drilled in it, into which belts are fastened with bolts.
9. To the part of the staircase on which the steps are not fixed, you need to weld a metal plate perpendicular to the frame. It is necessary to attach two metal plates to the other half of the frame; the upper step is welded to them on top.

In order to ensure reliable fixation, cuts are formed at the level with the support plate, which will serve as a lock.

Making your own stepladder (video)

Manufacturing of other types of stepladders

Some structures cannot always be conveniently transported in a disassembled state. To make the structure solid, the part on which the steps are located is made somewhat longer.

At a distance of 10-15 cm from the highest step, a special gap is drilled and cut in the profile pipe.

The ends of the halves are inserted into it without steps. These parts are soaked in milk and flattened. After this, a through hole is drilled in the frame, and the section of the structure is fixed with a lock nut.

In order to assemble a transforming stepladder, you should initially carry out a design calculation, and then perform the following steps:

1. 8 pipe sections of the same length are cut.
2. Steps are cut from a sheet of metal. The step size can be set to any size.
3. The steps are attached so that on both sides of the sections they are located at the same distance from each other.
4. Fitting is carried out and the sections are connected using locking mechanisms.
5. The stepladder is treated with a primer and coated with paint.

It is worth noting that the load on the locking mechanisms of a transforming stepladder is in most cases quite high, therefore it is necessary to form the welding connecting seam between the structural elements with the utmost quality.

To create a transforming ladder, you will need the same set of tools and materials as for the classic analogue of the design, but instead of belts, stop mechanisms will be used.

The technology for assembling a sliding stepladder is practically no different from the installation algorithm of the two previous types.

All load-bearing sections are made according to the transformer principle and are connected to each other via sliding mechanisms. In this case, the outermost two sections are connected to each other according to the principle of a conventional stepladder.

When designing any metal structures, the question arises - what kind of rolled metal and what cross-section should be used to ensure the reliability of the structure under the influence of expected loads. Methods can be found accurate calculations or use software resources that allow you to calculate almost any structure. However, this is almost always only possible for professionals who know how to use software, knowledgeable about technology production of metal structures and having knowledge of rolled metal products.

Very often, when constructing small and uncomplicated objects, for example, stairs to the second floor, you have to choose rolled metal based on experience, as they say “by eye”. In order to somehow justify your choice, and at the same time instill confidence in both yourself and the customer, we offer the simplest (“for beginners”) calculation option.

Let's say we need to build metal frame stairs to the second floor.

Let it be: the length of the stairs is 3m. , tilt angle 30 0, estimated load: 200 kg. – weight of the structure and 500 kg. – additional load. It is necessary to select a profile pipe for the load-bearing beam (string)

The calculation is carried out with a certain degree of approximation. Figure 1 shows a diagram of the staircase beam,

Fig.1 where:

L – beam length,

q – angle of inclination of the stairs

In our case: F = 500kg.

L = 300cm.

q = 30 0

P = 200kg.

For simplicity of calculation and, taking into account that in the end the staircase to the second floor will be quite rigid, allowing the load to be distributed, we will reduce the existing diagram (Fig. 1) to a diagram with a uniformly distributed load,

Fig.2 where: b is the horizontal component of the beam,

For our case: b = L *cos q = 300*cos 30 0 = 260 cm.

Q = F +P = 500kg.+200kg. = 700kg.

G= Q/ b = 700kg/260cm. = 2.7kg/cm.

Under the influence of loads, the pipe will begin to sag. With minor deflections, after removing the load, the pipe will return to its original state. If the load exceeds the permissible one, deformation (irreparable deflection) of the pipe may occur. In order to avoid deformation, it is necessary to compensate for the bending moment (arising from the action of the load) by the resistance moment of the pipe. In our case, the formula for the bending moment is:

M= q* b 2 /8 Substituting the data we get: M = 22815 kg.cm.

The moment of resistance of the pipe depends on the material of the pipe (stair beam) and is calculated by the formula:

W= M/ R, where: R – calculated metal resistance

pipes, for steel St.3 – R = 2100.

Substituting the values M And R , we get that W = 10.86cm3

The moments of resistance of profile pipes are calculated and tabulated, which can be found in the relevant Internet topics. Using the tables, we need to take pipes with W greater than that obtained in our calculations (> 10.86). The moment of resistance is greater than the value 10.86 for pipes 70x70, 80x80, etc. If we take a pipe 50x100, then on the side 100W = 24 cm3, i.e. almost two and a half times more than in our calculation. Thus, for the beam (string) of our stairs to the second floor, a 50x100 profile pipe is quite suitable. Rolled metal for the load-bearing elements of stairs should be taken with a three to fivefold margin against possible loads. Additionally, it is necessary to check the deflection of the beam (strings, stringers of the stairs). In the case of a uniformly distributed load, the deflection is determined by the formula:

f = 5 Gb 4/384 EI Where: f — maximum deflection

G – uniformly distributed load

b – horizontal projection of the beam

E – modulus of elasticity (tabular data)

I – moment of inertia (tabular data).

For our case G = 2.7 kg/cm., b = 260cm., E (for steel St.3) = 20.4*10 5 kg.cm 2 (reference data), I (for a pipe 50x100) = 137cm. 4 (tabular data). As a result:

f = 0.6 cm.

The deflection is insignificant, but at the beginning we simplified the problem and brought it to the option of a uniformly distributed load. In reality, the load will be concentrated and the deflection can be three times greater. On the other hand, we calculated only one beam (string, stringer). If we take classic version with two, for example, stringers, then the deflection will decrease again. In general, if the deflection is not permissible, then you should make supports, connect several pipes, or look for other options.

In conclusion, it must be emphasized that we did not try to make accurate calculations, but tried to prove that the 40x80 or 50x100 pipes used in the construction of stairs are quite the correct option.

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 the most aesthetically inclined.

These skills are good for building outdoor stairs. For interior spaces cottages, dachas and other multi-storey premises are suitable for interfloor stairs made of profile pipes, which 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 is a specific example of 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. Despite all this, not many people like it screw designs or almost vertical.

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 a pipe of the required length and a similar one, but 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.

See also the video of the assembly of the structure.

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