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 separation elements in fire divisions, evacuation stairwells, vertical shafts, etc., and possess a certain degree of fire resistance. In addition to the functions of a regular door, fire doors also serve to prevent the spread of fire and smoke, stopping the spread of fire for a certain period and ensuring the evacuation of personnel.
