Engineered to resist fire and smoke, fire doors capitalize on intumescent strips and seals that expand under high temperatures, forming a tight seal to thwart the passage of flames and gases.

These doors undergo rigorous testing and certification processes, ensuring their reliability and compliance with safety standards. Fire door assemblies are evaluated based on their fire resistance rating, which denotes the duration they can withstand fire while preserving their integrity.

The Inner Workings of Fire-Rated Steel Doors

Fire doors operate through a meticulously defined process that activates in the event of a fire:

Detection of fire or smoke: Fire alarms, smoke detectors, or other fire detection systems initiate the alarm sequence.

Activation of the fire door closing mechanism: Upon detection, an automatic mechanism triggers the closure of the fire door, sealing off the affected area.

Halting the spread of fire and smoke: By confining the fire to its origin, fire doors impede the progression of flames and the release of toxic gases, granting occupants more time to evacuate safely.

Ensuring unhindered evacuation routes: Fire doors assume a pivotal role in preserving clear evacuation routes, enabling occupants to escape swiftly while enabling emergency responders to access the building.

The Significance of Proper Installation and Maintenance:

To optimize the effectiveness of fire-rated steel doors, the significance of proper installation and regular maintenance cannot be overstated. Professional installation guarantees the correct fitting of fire doors, accompanied by the necessary components, thereby minimizing the risk of failure during a fire emergency.

Regular inspections and maintenance procedures prove indispensable in identifying any potential issues or damage that could compromise the performance of fire doors. Addressing common problems such as damaged seals, misaligned hinges, or worn-out door closers promptly ensures the integrity of fire doors remains intact.
