Just like a properly operating fire damper, is a key component in the compartmentalization of a building to stop the spread of deadly fire,
Smoke, and toxic fumes and gases. For the fire door to operate successfully the entire fire assembly must operate,
And the fire door is just one part of the overall fire assembly.
The assembly is composed of the fire door, frame, fire exit hardware, door closers, hinges, locks, door bolts, and other door
Components that when combined provide varying degrees of fire protection that is contingent on the door fire rating (e. G. 45 minutes, 90 minutes).

Vertically sliding; Chutes; And overhead rolling fire doors. Anti-fire steel door
