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-dividing elements in fire compartments, stairwells, vertical shafts, and other areas with certain fire resistance. In addition to the functions of a regular door, fire doors also have the capability to prevent the spread of fire and smoke, allowing for the containment of fire for a period of time to ensure the safe evacuation of personnel.

Use of fire doors: Commonly used in various buildings as closable fire separation components. Fire doors that meet requirements should possess good high-temperature resistance, heat insulation, and smoke penetration prevention capabilities. Additionally, they should automatically close after personnel have passed through during a fire, ensuring the effective separation of fire.
