Stairs on a metal frame are the most durable among all the others. For their manufacture, you must have a welding machine and have the skills to work with it. If all the work is done correctly, and after completion, the steel elements are treated with anti-corrosion compounds, then the structure will not need to be repaired for several decades.
Design features of steel stairs
Before starting work, you should select the type of frame. It can be a spiral or spiral, closed, open, rotary, mid-flight or arched staircase. Among other things, it is necessary to decide whether the structure will have a platform. If you intend to use a steel frame as a basis, then it must be made taking into account the presence or absence of sheathing. In the choice of decor options, you can not limit yourself, since the metal structure 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;
- grinder;
- electrodes for welding;
- pipe, corners, channel, profile;
- primer;
- rust protection.
Technological process
Stairs on a metal frame, the photos of which are presented in the article, can be made of steel elements that are most suitable for a particular design. You should not worry about their appearance, since after completion of work their surface will be covered with paint. As a carrier base, you can use channels, which are paired in pairs. Corners should be attached to these components of the stairs, which will form the basis of the steps. Instead of corners, sheet metal can be used, however, it must be taken into account that it involves more impressive labor costs, as it is difficult to process and fasten.
As the most suitable width for a flight of stairs, you can use a range within 0.8-1 m. Whereas the railing should not be lower than 90 cm. Steps should be given a height of 20 cm, and their width should not exceed 30 cm. As an acceptable slope, the figure of 38-450 has proven itself well. The distance between the march and the wall of the room should not exceed 5 cm.
Making a frame for a spiral staircase
Stairs on a metal frame can also be made on the basis of a screw structure. For creatingsuch a frame, a pipe should be used, which will act as the main pillar, while the steps should be made from a pipe of a larger diameter. The latter must be cut into separate sleeves, the length of each of which is 260 mm. The sleeves should sit well on the central rack, while it is necessary to exclude backlash and distortions. If it is not possible to select pipes of the required diameter, then o-rings must be used.
When making stairs on a metal frame, the next step is to weld the rings into the sleeves, after that it is recommended to grind using a manual milling cutter.
In order to make steps of identical size, it is preferable to make a special jig for them. Why should you prepare wooden slats and a pipe mandrel. The slats are glued together, in the end they should have the size and shape of a step.
The mandrel for the pipe can be made from chipboard blanks. Using such a jig, you can weld the steps by inserting the tubes and setting them at the desired angle. After that, you can proceed to welding the steps to the sleeves. The completion of the described process should be accompanied by the cleaning of the resulting roughness in the area of the seams. At the next stage, it is recommended to start assembling the frame. The sleeves must be put on the central post, and only after that the whole structure can be mounted in its place.
Strengthening stairs
Before the sheathing of the stairs on the metal frame is made, you cancarry out work to improve it. To do this, the lower area of \u200b\u200bthe rack can be concreted. After the steps are installed, they must be set at the required angle and paired using oversized racks. Now the surface needs to be prepared. To do this, the base is primed and painted, only after that the sheathing begins.
Sheathing the frame with wood
A ladder on a metal frame with your own hands can be sheathed, for which it is recommended to use wood. Wooden shields should be prepared for the site. The topmost riser should be fixed to the concrete floor with anchors. Fastener heads after the process must be treated with putty. In order to comfortably mount the risers, each element must be pulled to the wall using an elastic band. When adjusting the dimensions of steps and risers, it is necessary to leave minimal grooves. Wooden stairs on a metal frame look noble and serve for a very long time. If you do not want the steel elements to be visible, you can even make the railing wooden. Balusters for them are sold in the building supplies department. But you can make them yourself. However, in the latter case, the master must have the appropriate skills.
