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.

Fire door is one of the measures for building fire separation. It plays an important role in preventing the spread and spread of smoke and fire and reducing the loss.Some items of building hardware are essential to ensure that the fire resisting door stays closed in its frame in a fire emergency.
