Our thermoplastic stairs are flexible, strong, and built to withstand the elements. Not only is the strength built into the stair itself, every stair has a support system which is also set in concrete. The stairs are vacuum-formed from a single piece of ABS. Many shapes and styles are available in our Quaker Step Line, including contour, cantilever, in-wall ladder, leisure bench and corner. Thermoplastic Step models are available in White and Solid Gray (Solid Gray only offered in Cantilever).
Controlled Flexibility: All-plastic channels are permanently bonded to the underside of each tread, providing controlled flexibility. These patented, heavy-duty channels mean optimum strength while still allowing the stairs enough flexibility to withstand freezing and thawing.
Lock Down Bleacher System: The molded bottom shoes easily flip to the horizontal position and the stair is ready for installation. Precision-engineered leveling support posts and bottom shoes are permanently hinged at the factory to the Ridg-A-Dized support channel, strategically located under each tread. Leveling and support posts, along with the support shoes, are pre-drilled for rebars. Install rebar through holes, cover with concrete, and the stair is ready for final leveling before concrete hardens. Result: Level stairs with bleacher-type stability, strength, and support.Learn More
