Ladders 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 their 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 must select the type of frame. It can be a spiral or spiral, closed, open, pivoting, marching or arcuate staircase. Among other things, it is necessary to decide whether the site will have a structure. If you intend to use a steel frame as the basis, then it is necessary to manufacture it taking into account the presence or absence of cladding. You can not limit yourself to the choice of decor options, since the metal structure is able to withstand not only the load during operation, but also the weight of the finish made of any material.
Tools and materials
Ladders on a metal frame, as a rule, are made using certain materials and tools. Among them:
- welding machine;
- Sander;
- electrodes for welding;
- pipe, angles, channel, profile;
- primer;
- rust protection.
Technological process
Ladders 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 the supporting base, you can use channels, the pairing of which is done in pairs. On these components of the stairs must be attached corners that 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, since it is difficult to process and fasten.
A range of 0.8-1 m can be used as the most suitable width for the flight of stairs . While the railing should not be lower than 90 cm. The steps should be given a height of 20 cm and their width should not exceed 30 cm. In the role allowable bias well-established figure in 38-45 0 . The distance between the march and the wall of the room should not exceed 5 cm.
Manufacturing of a frame for a spiral staircase
Ladders on a metal frame can also be made on the basis of a spiral structure. To create such a frame, a pipe should be used, which will act as the main pillar, while the steps should be made of a pipe of a larger diameter. The latter must be cut into individual sleeves, each of which is 260 mm long. Sleeves should sit well on the central rack, while it is necessary to exclude backlashes and distortions. If it is not possible to choose pipes of the desired diameter, then it is necessary to use o-rings.
When making stairs on a metal frame, the next step is to weld the rings into sleeves, after which 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 conductor for them. Why should you prepare wooden slats and a mandrel for the pipe. Reiki stick together, in the end they must have the size and shape of the steps.
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 installing them at the desired angle. After you can proceed to welding the steps to the sleeves. The completion of the described process should be accompanied by a cleaning of the resulting roughness in the seam area. At the next stage, it is recommended to start assembling the frame. Sleeves should be worn on the central rack, and only after that the whole structure can be mounted in its place.
Strengthening the stairs
Before sheathing the stairs on the metal frame, it is possible to carry out work on its hardening. To do this, the lower area of the rack can be concreted. After the steps are installed, they must be set at the required angle and pair using the oversized bar-racks. Now the surface still needs to be prepared. To do this, the base is covered with a primer and painted, only after that the lining begins.
Wood paneling
The ladder on the metal frame with your own hands can be sheathed, for which it is recommended to use wood. Wooden boards should be prepared for the site . The top riser should be fixed to the concrete floor using anchors. The fastener heads must be putty after the process. In order to comfortably mount the risers, each element must be pulled to the wall using an elastic harness. When adjusting the sizes of steps and risers, it is necessary to leave minimal grooves. Wooden stairs on the metal frame look noble and last 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 department of construction products. But you can make them yourself. However, in the latter case, the master must have the appropriate skills.
