Usually the supporting bar is made of round tube (steel or stainless steel). But also bar constructions made of rectangular tube or as triangular bar provide an impressive appearance.
No matter whether you prefer wood, stone or glass as step covering – center rail stairs are an optical eye-catcher in every combination and are suitable for all coverings. A successful contrast is created by constructions in which the strength of the stringer is highlighted with the lightness of glass. Light woods also form a perfect “partner” to the dominating steel bar.
In the case of single stringer stairs, the supporting structure – as already defined in the name – consists of only one stringer. Due to this construction method they always present themselves as an impressive eye-catcher in the middle of living rooms or in modern staircases. Like a sculpture, single stringer staircases fit into every living scene as a design element. This appearance is especially characterized by a step construction, especially the setting steps.
