RediStair® is a patented slab-to-slab cantilever truss stair system that combines two independent precast concrete stringers with a site-cast intermediate landing, forming a cantilever truss supported by the upper and lower building slabs. Reinforcement continuity into the slabs provides a continuous load path. This approach eliminates the need for landing support seats, corbels, or welded components. The system serves hotels, apartments, condominium towers, student housing, parking garages, and other commercial projects.
