Fire doors are doors that can meet the requirements of fire resistance, integrity, and heat insulation for a certain period of time. They are fire-separating elements with certain fire resistance, installed in fire-divided areas, evacuation stairwells, vertical shafts, and other locations. In addition to the functions of ordinary doors, fire doors also play a crucial role in preventing the spread of fire and smoke. They can contain the fire for a period of time, ensuring safe evacuation of personnel.

Use of Fire Doors: Commonly used as movable fire separation components in various types of buildings. Fire doors that meet the requirements should have good heat resistance, insulation, and smoke-proof properties, and should automatically close after personnel have passed through during a fire, ensuring their fire separation function is effective.
