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.
