A round steel tube with a diameter of 42mm was fixed laterally at the inner stringer of the design stairs. It serves as handrail for the design stairs.
Another significant detail of the design stairs is the structural supporting underside cladding consisting of steel sheet. Matching the stairs flight MetallArt welded precisely designed steel sheets on the bottom part, evenly between the stringers of the design stairs. The surface of the steel cladding was supplied with a primary coat to be finished with a lacquering on site.
Directly at the head of the design stairs MetallArt installed a bridge which corresponds to the construction of the tread steps. It is however equipped with additional transverse ribs and steel sections between the stair stringers (number and dimension of the sections according structural needs). Another all-glass railing with laminated safety glass panes completes the bridge. It has however a uniform height and a top-attached stainless steel handrail.
