According to the method of fixing the steps and the type of supporting structure, there are such metal stairs:
– With mono stringer: a classic staircase, the main element of which is a load-bearing beam (string) with grooves for the steps.
– With side stringers (channels): the traditional way of fixing the steps, they are laid on top of an inclined beam (stringers). There can be from one to three such beams. Universal stairs on struts are suitable for installation in all types of premises.
– On the bolts: an ergonomic option for creating modular structures in the style of high-tech, which involves fixing the steps to the hinged balusters (huge bolts).
By type, staircase metal structures are:
- prefabricated;
- welded;
- forged.
By form:
- curved;
- straight;
- twisted;
- elliptical.
As a rule, the basis of any design is a metal frame. Our masters design it based on the size of the stairwell and the dimensions of the future structure; they also take into account the method of attachment: to the wall or additional support. Then they calculate the strength and select the appropriate range (screws, pipes, strips, channel bars).
Art Metal specialists will help you to prepare the base for each of the above options, select the right design, as well as provide all the necessary technical documentation.
