Fire doors are doors that can meet the requirements of fire resistance, integrity, and heat insulation for a certain period of time. They are installed as fire-rated partitions between fire compartments, evacuation stairwells, vertical shafts, and other areas with certain fire resistance. In addition to the functions of a standard door, fire doors also have the ability to prevent the spread of fire and smoke, allowing for the containment of fire for a certain duration and ensuring the safe evacuation of personnel.
