Due to their structural bearing capacity steel stairs offer an almost unlimited variety of design options. Therefore, the design of steel stairs in modern architecture no longer concentrates only on functional aspects; steel stairs have increasingly become a creative element of interior design. Because of its high structural capacity steel complies with the stringent static requirements even if the cross sections used are relatively small. Moreover, steel has properties that allow it to be shaped by (cold) rolling. Since 2014 MetallArt steel stairs have been marked with the legally required CE label.
Using the relevant technical know-how and modern machinery steel stairs can be designed as curved or spiralled constructions.
