Why Contractors and Building Owners Choose Steel Masters NYC
Steel Staircase Types We Fabricate
Steel Masters NYC fabricates every type of commercial and residential metal staircase. Indoor commercial staircases include closed tread diamond plate, open tread grating, and concrete-filled stair pan configurations for egress, basement access, and mezzanine applications. Outdoor steel staircases use galvanized steel for corrosion resistance with open tread grating or diamond plate treads and welded pipe railings. Fire egress staircases are fabricated for multi-story commercial and residential buildings requiring rated egress paths. Architectural and floating staircases are custom-designed for restaurants, lofts, retail spaces, and rooftop applications where design and function are both priorities. Multi-landing staircases handle long floor-to-floor runs with one or more intermediate landings — standard for warehouses, factories, and multi-story commercial buildings. All configurations include welded pipe railings, wall railings, or both as required.
