Fire doors are doors that can meet the requirements of fire resistance, integrity, and insulation for a certain period of time. They are installed as fire separation elements in fire compartments, stairwells for evacuation, vertical shafts, and other areas with certain fire resistance. In addition to the functions of a regular door, fire doors also play a crucial role in preventing the spread of fire and the diffusion of smoke, effectively containing the fire for a period and ensuring the safe evacuation of personnel.

Fire Door Usage: Commonly used as a movable fire separation component in various buildings.
