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 separation areas, stairwells, vertical shafts, and other locations with certain fire resistance. In addition to the functions of a regular door, fire doors also have the role of preventing the spread of fire and smoke, capable of stopping the spread of fire for a certain period of time to ensure the evacuation of personnel.
