Fire doors are doors that, within a specified time frame, meet the requirements for fire resistance, integrity, and insulation. They are installed in fire compartments, emergency stairwells, vertical shafts, and other fire-resistant partitioning elements. In addition to the functions of a standard door, fire doors also serve to prevent the spread of fire and the diffusion of smoke, effectively halting the progression of fire for a certain period to ensure the safe evacuation of personnel.

Fire door usage: Commonly used as movable fire-separation components in various buildings. Qualified fire doors should possess excellent high-temperature resistance, heat insulation, and smoke-proof performance, and should have the ability to automatically close after personnel pass through during a fire, ensuring their effective fire-separation function.
