Fire Rated Double-leaf Door
A Fire Rated Double-leaf Door is a type of door assembly consisting of two door panels (leaves) designed to provide fire resistance, typically rated to withstand fire for durations such as 90 minutes or 120 minutes, depending on specifications. These doors are built with materials like galvanized steel or stainless steel, often 1.2 mm thick shutter sheets, with internal fire-resistant insulation such as mineral wool or rock wool. The door frame is also fabricated for fire integrity and stability, sometimes using double rebates for better sealing.
Key features
- Fire rating: Usually up to 120 minutes (2 hours) for single-leaf fire doors.
- Material: Galvanized steel or metal with a shutter thickness around 45-46 mm.
- Frame: Steel frame profiles with galvanization and powder-coated finish.
- Hardware: Fire-rated door closers, stainless steel hinges, panic bars (for emergency exits), and locking mechanisms suitable for fire safety.
- Testing Standards: Compliance with standards such as BS 476, IS 3614, or relevant fire safety certification.
- Size: Common maximum sizes for single-leaf doors are approximately 1200mm width by 2100-2400mm height.
- Additional Options: Doors may feature vision panels with fire-rated glass to maintain visibility while ensuring fire resistance.
Such doors are used widely in commercial, industrial, public buildings, and emergency exit routes to ensure safe evacuation and property protection during fire incidents.
Fire Rated Double-leaf Door is a safety door designed to withstand fire exposure for a pre-defined time, helping to contain fire and smoke and providing safe egress paths during emergencies.
