The core function of fire doors
Jan 23,2026
Block the fire
By using refractory materials such as steel and wooden fire-resistant core boards and special structures, flames can be prevented from penetrating within a specified time and the spread of fire can be delayed.
Isolate smoke
Equipped with fireproof sealing strips, the door gap can be expanded and sealed during a fire to prevent the spread of toxic smoke and reduce the risk of personnel poisoning.
Ensure the safety of evacuation routes
Commonly used in key areas such as stairwells, elevator lobbies, and refuge floors to ensure unobstructed escape routes.
