Fire-resistant rolling door

Implementation Standard GB14102-2005 (Fire-resistant Rolling Shutter)

Fire resistance limit over 4 hours, smoke leakage not exceeding 0.2m²(m²/min)

Fire resistance performance: average temperature on the non-fire side not exceeding 140°C
Maximum single-point temperature rise not exceeding 180°C

Product features: long fire resistance time, meets the requirements for non-fire side lifting, smooth opening and closing operation, low noise, good sealing performance, suitable for various buildings with extremely high fire protection requirements

Special-grade inorganic fabric features: 1. The curtain is made of non-metallic materials treated with special processes and sewn, featuring flexible texture and high tensile strength. Its corrosion resistance and moisture resistance are more unique compared to steel rolling shutters (with sprinkler systems), offering better fire performance.
2. As the curtain is made of non-metallic materials, it has a small thickness and occupies less space, increasing the effective usable space in the same building and reducing the requirements for building height.
3. The curtain weighs no more than 5kg per square meter, only one-fifth of steel curtains, reducing the effective load requirements on the building.
4. No water curtain protection is needed, eliminating water supply pipelines and control equipment, reducing firefighting water consumption, and significantly lowering project costs.
5. Flexible operation and low noise.
