# How to build a metal staircase to the second floor with your own hands in a private house: Instruction + Photo and Video

Some people do not want to build a one-story house and are building a multi-storey one, and it will be impossible to move around the house without stairs. Ladders come in a variety of shapes and materials. The stairs that are between the floors are made of wood, metal and concrete.

## Do-it-yourself metal staircase to the second floor

In the article we will tell about a staircase made of metal, which will be located between the floors. But the properties that metal has make it possible to manufacture stairs of any design and at the same time strong, lightweight, beautiful, even airy stairs.

The construction of a simple staircase to another floor with one flight is not difficult, if you have some skills. But a staircase with several flights is more difficult to make, but you can learn everything, if you wish.

Ladders can be wooden, metal or concrete.

The design and calculations for stairs located between floors from any materials are no different.

They have the usual requirements:

• In a private house, the smallest staircase width is 900 centimeters.

• The normal step height is 160 - 180 millimeters.
• The minimum allowed step depth is 270 millimeters.
• The railing on the stairs should withstand the lateral pressure of about one hundred kilograms.
• The distance between the handrail posts should be 150 millimeters and, if there are children in the family, this distance should be 120 millimeters.

Ladders are of the following types:

• On kosoura. On one stringer, that is, on an I-beam or channel. They play the role of a support, they are placed in the middle of the structure and the steps are attached. These stairs look airy, light, but withstand the load with dignity.
• On the string.

• On the bolts.
• Screw.

There are stairs :

• one-flight and two-span;
• straight and with a turn.

If you do not have special skills in building stairs, then start with a simple option, then there is a single-march design.

## Required calculations

In organizations that are engaged in development projects, use special computer programs, with the help of these programs they design 3D models of structures.

In a 3D model, it is very easy to change the parameters of different parts.

After approval of the final version, the computer program prepares the specification and drawings of the metal staircase.

But in our case, the calculations will have to be done without the help of a computer program. We will consider a simple version of a direct one-march construction.

The basic requirements for the depth and height of the steps are already known.

It is necessary to make measurements between the points, that is, from the beginning to the end of the stairs from the floor of the first floor and the height between the floor of the first and second floors. Now we determine the length of the stairs, we must remember that the average angle of inclination is from thirty to forty-five degrees.

To calculate the length of the stairs, you need to remember the geometry, that is, about a right-angled triangle. Indeed, in a right-angled triangle, the square of the hypotenuse is equal to the sum of two squares of the legs.

We calculate the available parameters and extract the square root and get the length of the stairs.

Next, a suitable number of steps must be calculated.

## Materials and tools required for work

For the construction of an interfloor metal staircase, in order to build an interfloor metal staircase, we need the following tools and materials.

Tools :

1. welding machine;
3. grinder ;
4. welding mask, gloves and special glasses;
5. drill with metal drills;
6. grinding discs;
7. stable table made of metal;
8. vice;
9. clamp;
10. pencil;
11. tape measure and square;

Materials:

1. Primer;
2. White - spirit;
3. Paint for metal
4. Also for two kosour use a square pipe from a profile.
5. In order to weld the step supports, reinforced corners are required.
6. The steps and risers themselves are made of four-millimeter steel and trimmed with wood.

### Work performance

Stages of work:

• Cutting blanks;
• Making fillets, that is, nodes for connecting steps;
• Welding support corners;
• Installation of stringers;
• Welding steps and railings;
• Grinding;
• Primer and painting;

First of all, angles are made from the corners for fastening the steps, that is filly.

It is impossible to make a mistake so that there are no various distortions and flaws that will ruin the stairs.

In the same way, filly must be the same and must be exactly opposite each other. Fillets are made from a corner by cutting a sample and joining the corners together.

As a result, L-shaped nodes are obtained with shelves down and inward.

For our design, fourteen pairs of these nodes are needed, and in each of the pairs one support will be left, and the second right. Then we weld the brackets to connect the steps and the horizontal bar between each of the pairs of corners.

We also make the horizontal crossbar from the corner. The structure is reinforced with kerchiefs, we weld them from the bottom of the steps towards each of the stringers.

Along the edge of the square pipe from the profile, we make markings and, according to the marking, we weld the filly to the edge of the kosour, the second kosour is attached to the first kosour with fillets and transfer the marking.

We check the level and then weld the stringers with the lower end to the support platform. If the houses have a concrete foundation, then the support platform is installed in concrete. We attach the upper end to the support post, the support post is fixed to the ceiling between the floors with steel anchors. Then once again the filly must be checked by level.

In the event that the staircase is made near the wall, then to give the structure, rigidity, one stringer is welded to the brackets that are fixed to the wall.

Finishing work consists in welding the steps to the filly, you can also fix them with bolts, but in this case it is necessary to sheathe the steps with wood. Also, the steps can be installed wooden, on the filly using screw connections.

### Tips for installation

It seems that the construction of an interfloor staircase is not such a difficult task, but this work requires precision, accuracy and care ...

1. The upper step is mounted at a short distance from the wall, it is very important that between the wall and the step there is a gap so that the wallpaper sheet passes.
2. The railing is always welded to the side of the staircase so as not to change its width.
3. All parts in the welding places are ground, that is, all seams, notches and burrs, then metal particles are swept away with a metal brush. After that, the metal staircase is primed and painted.
4. Wooden steps are installed after the paint is completely dry.

5. High-quality welding works are the guarantor for the ladder's long service life. And the anti-corrosion coating will protect the metal from damage for a long time.
6. Over time, a metal staircase can be finished with different materials and due to finishing it will not look bulky.
7. If you are suddenly not confident in your abilities, or do not know how to do some kind of work, then it is best to use the services of professional workers.
8. The main factor in choosing a metal staircase is cost savings.

9. A ladder, first of all, should be comfortable, not too steep and not very sloping.

In the article, we described how to make a metal staircase to the second floor.

Of course, it is up to you and no one else to decide what material to make a staircase from, but a staircase made of metal turns out to be visually light, so we recommend this particular design.

We hope this information was useful to you. We wish you good luck, patience and inspiration!
