Fire doors are a special type of door with fire-resistant functions, primarily used to prevent the spread of fire and smoke, ensuring the safety of personnel and property. Their core features include:
Fire Resistance: Fire doors are classified into different grades based on their fire resistance rating (e.g., Class A, Class B, Class C), with fire resistance times ranging from 0.5 hours to 3 hours, depending on the door materials and structural design.
Various Materials: Common fire door materials include steel, wood, steel-wood, and glass fire doors. Steel fire doors have high strength and good fire resistance; wooden fire doors are aesthetically pleasing but require special fire-retardant treatment; glass fire doors balance light transmission and fire resistance.
Sealing Performance: Fire doors are typically equipped with fire-resistant sealing strips, which expand when heated to effectively block the spread of smoke and toxic gases.
Automatic Closing Function: Most fire doors are equipped with door closers to ensure automatic closure in the event of a fire, preventing the spread of fire.
Durability: Fire doors must pass rigorous national standard tests (such as GB12955-2008) to ensure stability and reliability under long-term use.
Wide Range of Applications: Suitable for high-rise buildings, shopping malls, hospitals, factories, warehouses, and other locations with high fire protection requirements.
Customization Services: Sizes, colors, and opening methods (hinged, sliding, etc.) can be customized according to customer needs.
Matching Hardware: Requires the use of specialized hardware such as fire-resistant locks and fire-resistant hinges to ensure overall fire resistance.
Strict Installation Requirements: During installation, attention must be paid to filling the gaps between the door frame and the wall with fire-resistant material to ensure overall sealing.
Easy Maintenance: Routine maintenance only requires periodic checks of the door closer, sealing strips, and other components; no special maintenance is required.
