Fire doors are generally heavy enough to provide the proper fire protection, and to ensure a smooth switch, it is also required to be hinged to the door frame. If the fire resistance of the hinge itself is not strong, it will definitely become the short board of the whole door. Therefore, all fire door hinges must be made of high quality stainless steel and must be strong to avoid deformation under high temperatures.
The appropriate specification and correct selection of hinges is crucial to their performance. It must achieve a reliable strength, not only requires the weight of a door to be able to withstand the normal time, but also requires no serious deformation or damage under the impact of external force. Otherwise, once it is deformed, it will easily lead to the whole door not being opened, and if such a thing happens in a fire, it will inevitably affect the escape of the person. For the architect or the owner, it is necessary to fully consider these door hardware when decorating, and the door ironmongery must be meet the international standard.
