Steel stringer stairs for modern architecture

Stairs are being used less and less for their intended purpose in architectural sketches these days. Instead, planners are making it their task to stage a staircase in the living space.

No other material is better suited to the construction of stringer stairs than steel: raw and light at the same time, because the structural load-bearing capacity allows delicate and filigree-looking cross sections of the load-bearing stringers to be achieved.

Steel stringer staircases have always been considered the classic in staircase construction, both for straight and curved constructions - made of flat steel or box stringers, depending on the structural requirements. The treads welded between the stringers can be made of flat steel, as trough treads or folded treads. Wooden tread coverings harmonize perfectly with the steel supporting structures. The combination of steel with glass treads is also a successful variant.

Steel stringer stairs are also suitable for using the box stringer of the supporting structure as a mount for glass railings. Stairs with parapet-high steel stringers, which are in line with the current architectural trend, also belong to this category - this type of steel stringer staircase is also referred to as a parapet stringer staircase.

A closed, smooth steel soffit lining is ultimately considered a design element of modern architecture and is welded in between the stringers according to the course. This creates an almost sculptural character, particularly with curved steel stringer stairs.
