Some items of building hardware are essential to ensure that the fire-resisting door stays closed in its frame in a fire emergency.

When use in a fire-resisting door assembly, the door leaf should be hung on single-axis hinges in accordance with local and national regulations. Hinges fitted to fire-resisting doors should be able to achieve the intended fire rating, also the hinge should be able to allow the door closing device, when fitted to a fire-resisting door assembly, to close the door leaf reliably from any angle to which it has been opened, overcoming the resistance of a latch or any seals when fitted.

The normally closed fire doors in public passages will affect the ventilation and lighting, and the passage is inconvenient. If the management is not good, it will lead to the failure of the door closer and the hoisting hardware, which is not conducive to the normal use of the fire doors. The maintenance and maintenance of the fire rated metal doors should be strengthened in the use process.
