Some design ideas for metal stairs include metal rippling ribbon stairs, steel stairs that resemble a giant backbone and floating folded triangular facets. The latter contains triangular steps made out of steel with a glass side in which to anchor them.
The rippling ribbon stairs are made from a single piece of sheet metal that runs back and forth to create the rippling ribbon effect. The metal is painted white on one side and black on the other to enhance the look. Only one side is attached to the wall with external side joists. In another creative design, steel is molded into a segmented backbone frame complete with ribs that serve as part of the railing. Timber and glass steps are set onto the frame to complete the design.
