Stairs on metal frame: manufacturing features

Stairs on the metal frame are the most durable among all the others. For their manufacture it is necessary to have a welding machine and have the skills to work with it. If all the work is done correctly, and after they are finished processing the steel elements with anti-corrosion compounds, the structure will not need repair for several decades.

Structural features of steel staircases

Before you begin, you must select the type of frame. It can be screwed or spiral, closed, open, rotary, march or arcuate ladder. Among other things, it is necessary to decide whether the construction will have a platform. If you intend to use a steel frame as a base, then it must be made taking into account the presence or absence of the skin. In the choice of options for the decor, you can not limit yourself, since the metal construction is able to withstand not only the loads during operation, but also the weight of the finish made of any material.

Tools and materials

Stairs on a metal frame, as a rule, are made using certain materials and tools. Among them:

• welding machine;
• Sander;
• Electrodes for welding;
• Pipe, corners, channel, profile;
• primer;
• Protection against rust.

Technological process

Stairs on the metal frame, photos of which are presented in the article, can be made of steel elements, which are most suitable for a certain design. On their appearance, do not worry, because after the completion of work, their surface will be covered with paint. As a carrier base, it is possible to use channels, pairing of which is done in pairs. These parts of the stairs should be attached to the corners, which will form the basis of the steps. Instead of corners sheet metal can be applied, however it is necessary to take into account that it assumes more impressive labor costs, since it is difficult to process and fasten.

As the most suitable width for a ladder march, you can use a range of 0.8-1 m. While the railing should not be below 90 cm. Steps should be given a height of 20 cm and their width should not exceed 30 cm. In the role The allowable bias of the well-established indicator in 38-45 ⁰ . The distance between the march and the wall of the room should not exceed 5 cm.

Making a skeleton for a spiral staircase

Stairs on the metal frame can be made on the basis of a screw structure. To create such a frame, use a pipe that acts as the main pillar, while the steps should be made of a larger diameter pipe. The latter must be cut into individual sleeves, the length of each of which is 260 mm. The sleeves should sit well on the central pillar, while avoiding backlashes and misalignments. If it is not possible to select pipes of the correct diameter, then it is necessary to use o-rings.

Making the ladders on the metal frame, the next step is to weld the rings into the sleeves, after which it is recommended to make a grinding using a manual milling cutter.

In order to make steps of an identical size, it is preferable to make a special conductor for them. For this purpose it is necessary to prepare wooden slats and a mandrel for a pipe. Reiki are glued together, in the end they must have the size and shape of the step.

The mandrel for the pipe can be made from chipboard blanks. Using this conductor, you can weld the steps by inserting tubes and installing them at the desired angle. After that, you can proceed to weld the steps to the sleeves. Completion of the described process should be accompanied by cleaning of the formed roughnesses in the area of the joints. The next step is to start assembling the frame. The sleeves should be put on the central rack, and only then the entire structure can be mounted in its place.

Strengthening the ladder

Before the lining of the ladder on the metal frame is made, it is possible to carry out work on its hardening. To do this, the lower rack area can be concreted. After the steps have been installed, they must be set at the required angle and mate, using oversized racks. Now the surface needs to be prepared. To do this, the base is covered with a primer and painted, only after this the skin begins.

Wood carcass lining

The ladder on the metal frame by its own hands can be sheathed, for which it is recommended to use wood. For the site, wooden shields should be prepared . The uppermost riser should be fixed to the concrete floor by means of anchors. Heads of fasteners after the process must be treated with putty. In order to make it comfortable to mount the risers, each element must be pulled to the wall using a flexible tourniquet. When adjusting the sizes of steps and risers, it is necessary to leave the minimum grooves. Wooden staircases on the metal frame look noble and serve a very long time. If you do not want the steel elements to be visible, you can even make the railings wooden. Balusters for them are sold in the department of construction products. But you can make them yourself. However, in the latter case, the master must have the appropriate skills.
