Fire doors are doors that can meet the requirements of fire resistance, integrity, and heat insulation for a certain period of time. They are installed as fire partitions between fire zones, emergency stairwells, vertical shafts, and other fire-resistant barriers. In addition to the functions of a standard door, fire doors also serve to prevent the spread of fire and smoke, effectively stopping the spread of fire for a period of time to ensure the safe evacuation of personnel.
Use of Fire Doors: Commonly used in various buildings as removable fire-separation components. Fire doors meeting the standards should possess good high-temperature resistance, heat insulation, and smoke-proof properties. Additionally, they should automatically close after personnel have passed through during a fire, ensuring their effective fire-separation function.
