Commercial Fire-Rated Garage Doors

Overhead Doors

Designed to close automatically in an alarmed event, our fire-rated doors are available for service door and counter applications in commercial projects.

Overhead Door Corporation offers a wide array of rolling steel doors to meet the most demanding fire safety standards, unusual opening sizes and discerning aesthetic requirements. Designed to close automatically in the event of a fire or alarmed event, our fire-rated doors are available for service door and counter applications in commercial, industrial, institutional and retail projects.

All doors comply with NFPA-80, and are listed for both masonry and non-masonry applications — including installation to wood or steel jambs within drywall. The Fire Sentinel® time-delay release device provides an added measure of safety to control the doors’ closure. Our FireKingTM Fire Doors feature an innovative floor reset hoist system, designed to eliminate the need to release a fire door’s spring tension on fire drop mode and allows one person to reset the door from the floor.
