Galvanized Steel Fire Door

Space-Saving & Versatile Design

Vertical or Horizontal Roll-Up: Adapts to tight spaces with minimal overhead clearance.

Custom Sizes & Configurations: Available for large openings (e.g., up to 10m wide × 6m high) and curved tracks.

Additional Safety Features

Smoke Sealing: Inflatable or brush seals expand under heat to block toxic smoke (meeting EN 12101-3 for smoke control).

Safety Sensors: Infrared or photoelectric sensors prevent accidental closure on obstacles.

Sound Insulation: Reduces noise transmission by up to 40 dB, ideal for residential-commercial mixed spaces.

Durability & structural integrity

Heavy-duty materials: constructed with galvanized steel or aluminum alloy slats, reinforced with steel guides for impact resistance.

Corrosion protection: powder-coated or anodized finishes ensure longevity in harsh environments (e.g., warehouses, parking garages).

Wind load resistance: tested to withstand high wind pressures (e.g., en 12424 class 5), ideal for industrial facilities.

Unmatched fire resistance

Certified protection: engineered to meet international standards (e.g., en 16034, ul 10b/c), with fire ratings from 1 to 4 hours (class a per gb14102).

Heat-activated automation: automatically deploys upon detecting heat or smoke, integrating with fire alarm systems for instant response.

Fireproof core: filled with rock wool or ceramic fiber insulation to block flames and reduce heat transfer.
