Automatically Closing Fire Resistance Powder Coated Infill Steel Hinged Emergency Exit Doors

Steel fire doors are a type of door used as part of a passive fire protection system inside buildings to prevent the spread of fire or smoke between sections. The wing of a fire door is a swinging door panel that also complies with the regulations marked fire, smoke seal, door fittings and the structure holding the fire door assembly. The edges of fire doors should usually have fire seal marks, which can be assembled from a strip that expands when exposed to heat. Most fire doors must always be closed, but some are designed to remain open under normal circumstances and to close automatically in the event of a fire.
The movement of the door should never be restricted by a door stop or other obstacle. The appliance and the smoke seal of the fire door must be checked regularly, such as the door closer and the handle.
