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 separators 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, allowing them to stop the spread of fire for a certain period and ensure the evacuation of personnel.

Additionally, they should automatically close after personnel have passed through during a fire, ensuring their effective fire separation function.
