Fire-Rated Doors

Overhead Door of Columbia 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 uses.

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-relay release mechanism provides an added measure of safety to control the doors' closure. Also available is the Fire Minuteman Chain Reset Hoist, 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.
