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-separated areas, evacuation stairwells, vertical shafts, and other locations with certain fire resistance. In addition to the functions of ordinary doors, fire doors also have the role of preventing the spread of fire and smoke, which can stop the spread of fire for a certain period of time and ensure the evacuation of personnel.

Fire Door Usage: Commonly used as a closable fire separation component in various types of buildings. Fire doors that meet the requirements should have good heat resistance, insulation, and smoke-proof properties, and should automatically close after personnel pass through during a fire, ensuring their fire separation function is fully utilized.
