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 in fire-separated areas, evacuation stairwells, vertical shafts, etc., and serve as fire-resistant barriers. In addition to the functions of a regular door, fire doors also play a crucial role in preventing the spread of fire and smoke, effectively containing the fire for a period to ensure safe evacuation of personnel.

Fire Door Usage: Commonly used as a movable fire separation component in various types of buildings. Required fire doors should have excellent heat resistance, thermal insulation, and smoke penetration prevention capabilities. Additionally, they should automatically close after personnel pass through during a fire, ensuring their effective fire separation function.
