While normal doors will require two hinges, wooden fire doors must be equipped with a minimum of three fire certified hinges. However, steel fire doors should have at least four hinges depending on the certification of the door. But your fire door may require more.
Fire door hinges should also be placed 200 millimetres from the top and bottom of the door with a third hinge being fixed an equal distance between them. If a fire door requires four hinges, they should be equally spaced apart and placed at the bottom and the top of the door.
