UL Fire-Rated
NAAMM HMMA Compliant
60 minute fire rated temperature rise doors are engineered to withstand fire exposure for one hour while limiting heat transfer through the door assembly to protect egress routes. Fabricated with temperature rise cores in 18 to 12 gauge steel, these UL fire-rated doors suit commercial, institutional, and life-safety installations.




A 60 minute fire rating indicates that a door assembly has undergone rigorous testing to withstand fire exposure and structural failure for a full hour. When combined with a temperature rise core, the door limits radiant heat transfer through the opening, helping protect egress routes, stairwells, and occupants during commercial building evacuation.
