Fire-Resistant Roll-Up Doors

Steel Fire Shutters: Constructed from 0.8–1.2mm galvanized steel panels with inorganic insulation cores. Used in industrial settings (e.g., warehouses, garages) where structural integrity and >3-hour fire resistance (per GB 7633/EN 1634) are non-negotiable. Superior Inorganic Fabric Shutters: Employ dual-layer curtains woven from stainless-steel-reinforced glass fibers (e.g., high-silica cloth) coated with fire-retardant polyurethane/silicone. These achieve UL 94 V-0 flame propagation ratings while remaining flexible—ideal for atriums or curved installations.
