Steel stairs & glass railing for Prediger showroom

The staircase construction presents ambitious architecture with characteristic appearance and connects both floors of the showroom at a central position. In keeping with the upmarket portfolio of the lighting specialist Prediger, the steel staircase with its curved all-glass railing and smooth underside cladding matches the sophisticated interior design of the store. As a self-supporting construction, it leads to the upper floor without static supports or wall-side fastenings. The resulting forces are absorbed solely by the floor and ceiling.

The all-glass railings, consisting of a composite of thermally toughened safety glass panes bonded with PVB film, not only offer maximum transparency but also simple aesthetics and guarantee the necessary fall protection for the steel staircase. On the inner and outer run of the glass railings, the supporting structures act as load-bearing stringers and also serve to hold the curved glass panes. These protrude freely from the supporting structure and were attached and visually sealed using a testable casting technique.

The realisation of staircase constructions with parapet-high glass railings is subject to complex technical regulations and structural specifications and therefore requires the utmost precision and expertise during both production and assembly.
