A door usually needs standard hinges to connect the door slab and frame.What are the requirements for hinges on a fire door?


Ball bearing-type hinges with steel base material are the allowable standard for rated hinges. NFPA80 includes criteria for the use of hinges or pivots that do not meet the requirements listed in the standard, for example, hinges of a different material, size, or bearing type. Continuous hinges and spring hinges must be tested and labeled for use on a fire door. 


Spring hinges are self-closing hinges. A spring mechanism in the barrel allows the hinges to automatically close a door. With field-adjustable closing power, the spring hinge line consists of standard commercial grade door hinges. It can replace the door closer on fire-rated doors.
