A fire door is a door with a fire-resistance rating (sometimes referred to as a fire protection rating for closures) used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a structure and to enable safe egress from a building or structure Fire rated steel doors expand into their frame under heat, sealing off a room where a fire has broken out to prevent the spread of smoke and flames. Fire rated doors play an important role in emergency fire procedures and can be installed to help your building comply with fire safety legislation. We offer these from 45-180 minutes fire rated doors. This means the door will perform as intended for up to 180 minutes. Fire rated doors are best used internally to secure rooms where fire risk is high or to secure rooms containing combustibles or other contents susceptible to fire.
