Fire doors play an essential part in any building. Fire door require the use of high-quality fireproof hinge. So what are the requirements for high-quality fireproof Hinges?
1. Heat Resistance
Fire doors are generally heavy enough to provide the proper fire protection, and to ensure a smooth movement, it is also required to be attached to the door frame. If the fire resistance of the hinge itself is not strong enough, it will definitely become an obvious defective of the whole door. Therefore, all fire door hinges should be made of premium stainless steel and strong enough to avoid deformation under high-temperature situations.
2. Structural Strength
The appropriate specification of hinges is crucial to their high-performance. Not only should it be able to withstand the weight of a door, but also it should not be deformed under external force. Once deformed, the door will be likely to be unopenable, which is the last situation we’d like to encounter in a fire, as the escape will be consequently impeded. For the architect or the proprietor, it is necessary to make a prudent decision on door hardware selecting when decorating, and the hardware store must meet the international standard.
3. Easy To Disassemble
The hinges for fire door need to be easily disassembled, since once the fire door is deformed and unopenable in an accident, all you are required to do is to disassemble the hinges then run for your lives!
Which tests should a fireproof hinge passed?
The trend of globalization, the ever-changing purchasing behavior, the increasingly fierce competition... In the era of rapid and continuous development, current consumers are purchasing premium goods. In addition to taking cost-effectiveness into account, their expectations are increasingly connected to the safety, quality and ecological requirements. Therefore, we may say that the key for an enterprise to stand out is to acquire relevant certificate.

1. American National Standard Institute (ANSI). Test content: ANSI/BHMA A156.1 Butts and Hinges. This Standard establishes requirements for butts and hinges. Cycle tests, lateral and vertical wear tests, friction tests, strength tests, finish tests, materials and dimensional requirements are included.
