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 a regular door, fire doors also play a crucial role in preventing the spread of fire and smoke, allowing for the containment of fire for a period of time to ensure safe evacuation of personnel.
