Fire safety systems rely on reliable compartmentalization, and doors play a critical role in that process. The fire proof steel door is designed to act as both a daily access point and a protective barrier during emergencies.
The door panel consists of double-layer steel sheets with fire-resistant core materials. Depending on requirements, fire ratings can be configured to meet different standards. This allows the fire proof steel door to slow down heat transfer and contain flames within designated areas.
A key feature is the use of intumescent seals. When exposed to high temperatures, these seals expand to close gaps around the door, helping block smoke and toxic gases.
The hinge and closing systems are designed for fire conditions. Automatic closing mechanisms ensure the door returns to a closed position during emergencies, even if left open during normal use.
Operationally, the door remains stable and easy to use in daily situations. Opening speeds are controlled to ensure smooth movement without compromising sealing.
The fire proof steel door can be connected to fire alarm systems, allowing automatic response when smoke or heat is detected.
Safety features also include manual override options, ensuring the door can be operated during power failure.
Because of its protective function, the fire proof steel door is widely used in stairwells, corridors, industrial buildings, and fire-rated partitions.
