UL Standards Steel Fire Rated Single Swing Door

UL Standards Steel Fire Rated Single Swing Door

Fire rated door is a door that can meet the requirements of fire resistance stability,

integrity and thermal insulation within a certain period of time.
It is a fire partition with certain fire resistance, such as fire compartments, evacuation stairwells, vertical shafts, etc.

In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke,

which can prevent the spread of fire within a certain period of time and ensure the evacuation of people.

Fire doors are generally located in the following locations:
(1) Close the evacuation stairs, leading to the aisle; close the elevator room, leading to the front room and the door leading to the aisle from the front room.
(2) Inspection doors for vertical pipeline wells such as cable wells, pipeline wells, flue exhaust ducts, and garbage ducts.
(3) Divide the fire compartment, and control the fire wall and the door on the fire partition wall set up in the building area of the compartment. When it is difficult to set up a fire wall or a fire door in a building, a fire shutter door should be used instead, and it must be protected by a water curtain.
