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 partitions between fire compartments, emergency stairwells, vertical shafts, and other fire-resistant separation elements. In addition to the functions of a regular door, fire doors also have the capability to prevent the spread of fire and smoke, effectively stopping the spread of fire for a period of time to ensure the evacuation of personnel.

Fire Door Usage: Commonly used as movable fire separation components in various buildings. Compliant fire doors should possess excellent heat resistance, insulation, and smoke-proof properties, and should automatically close after personnel pass through during a fire, ensuring their fire separation function is effectively utilized.
