Metal Fire Rated Doors

A Metal Fire Rated Door is a specially engineered steel door designed to resist fire, heat, and smoke for a specified period (commonly 30, 60, 90, or 120 minutes). It is an essential component of passive fire protection systems used in buildings to prevent the rapid spread of fire and provide safe evacuation time for occupants.

These doors are manufactured using galvanized steel sheets with fire-resistant core materials such as rock wool, mineral wool, or honeycomb insulation. The robust construction ensures stability, integrity, and insulation during fire exposure.

Key Features :-

Fire resistance rating from 30 minutes to 120 minutes depending on design. Constructed with double skin galvanized steel sheets for durability and strength. Fire-resistant core insulation (rock wool, mineral wool, or honeycomb). Shutter thickness typically around 40–46 mm. Powder-coated or painted finish for corrosion resistance and aesthetics. Compatible with fire-rated hardware such as hinges, panic bars, door closers, and locks.

Applications ;-

Metal fire rated doors are widely used in:

- Commercial buildings

- Hospitals and schools

- Industrial plants and warehouses

- Hotels and residential high-rise buildings

- Staircases, corridors, and emergency exits

These doors help compartmentalize fire within a building, reducing the spread of flames and smoke while allowing occupants time to evacuate safely.

Standards & Testing

Metal fire rated doors are generally tested and certified as per standards such as:

IS 3614 (Part 2)

BS 476 Part 20 & 22

These standards evaluate the door’s stability, integrity, and insulation during fire exposure.
