stairplane® staircases are handcrafted using high-grade aluminium, which is design-neutral and can be combined with wood, stone or industrial floors. Aluminum is the third most abundant element on earth after oxygen and silicon – it won’t age badly and will still look modern and timeless for decades.

High-grade aluminum is used in everything from computers and phones (Apple) to windows and doors (Alumil), in luxurious automobiles (Porsche, Jaguar), timeless furniture (the Eames chair) and on famous buildings (Empire State Building) designed by world class architects. The modern skyscraper could not be built without aluminum, in fact, the Empire State Building was the first building to use massive amounts of aluminum in its construction in 1930. Aluminum is also used for airplanes, and since some of our treads look like airplane wings, we proudly present you stairplane®!
