Why TERRAZZCO Terrazzo Self-Supporting Stairs?

Self-supporting stairs are an interesting architectural solution that improves the aesthetics of any institutional, commercial or industrial space. Self-supporting terrazzo stairs are free-standing which gives them a lighter elegant appearance. The treads are supported by stair stringers without any supporting wall. These stair treads are built to fit various stair designs including straight and curved staircases.


For safety, abrasive channels are cut into the surface of the stair tread and filled with TERRAZZCO Brand epoxy resin and silicon carbide. This produces an anti-slip tread.


Concord Terrazzo professionals offer fully customizable solutions for architects and designers. Designers can craft a beautiful staircase for locations like schools, hospitals, or any architectural project using cost-effective and environmentally-friendly terrazzo materials.
