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.

Due to tooling costs and similar considerations, variations of hinge sizes and fixing methods are not easily accommodated on a steel door. Steel door manufacturers generally provide their own steel hinges, which otherwise comply with these requirements, as part of the fire-resisting steel door-set and these are covered by evidence of performance.

Fire rated doors are doors that meet the requirements for fire resistance stability, integrity and insulation for a certain period of time. The use of matching door hardware can maximize the effectiveness of the fire door. So we need door hardware that also has a fireproof effect. In order to play the role of normal opening and closing of the fire door in the event of fire, the fire door hinge must be certified to install the fire door.

The building inspection services help identify critical fire, life safety and security building improvements needed to achieve code compliance with the ultimate goal of achieving fire, life safety and security of the building.

Fire rated doors can meet fire resistance stability, integrity and insulation for a certain period of time. It is a fireproof partition with certain fire resistance, such as in fire compartments, evacuation stairwells, and vertical shafts. In addition to the function of ordinary doors, fire doors have the function of preventing the spread of fire and the spread of smoke, which can prevent the spread of fire for a certain period of time and ensure the evacuation of personnel.
