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 separation elements in fire divisions, evacuation stairwells, vertical shafts, and other locations with certain fire resistance. In addition to the functions of ordinary doors, fire doors also play a crucial role in preventing the spread of fire and smoke, allowing for the containment of fire for a certain duration to ensure the safe evacuation of personnel.

Use of fire-resistant doors: They are common closable fire-separating components in various buildings. Fire-resistant doors that meet requirements should have good heat resistance, thermal insulation, and smoke-proof performance, and should be equipped with an automatic-closing function after personnel pass through during a fire, ensuring their fire-separating function is effective.
