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 partitions in fire compartments, evacuation stairwells, vertical shafts, and other locations with certain fire resistance. In addition to the functions of ordinary doors, fire doors also play a crucial role in preventing the spread of fire and smoke, effectively stopping the fire's progression for a period of time to ensure safe evacuation.

Fire Door Usage: Commonly used as movable fire separation components in various buildings. Qualified fire doors should possess excellent heat resistance, insulation, and smoke-proof properties.
