The Structural Components Of A Fire Door

Fire doors are generally installed in the following locations:

 

Doors enclosing evacuation stairwells and leading to corridors; doors enclosing elevator shafts and leading to vestibules, and doors connecting vestibules to corridors.

 

Inspection doors for vertical shafts such as cable shafts, pipe shafts, smoke exhaust shafts, and refuse chutes.

 

Doors in firewalls and fire-resistant partitions that divide fire compartments and control the building area of ​​each compartment. When it is difficult to install firewalls or fire doors in a building, fire-resistant rolling shutters should be used instead, and they must be protected by a water curtain.

 

Doors in partitions separating dwelling units that require fire and smoke protection according to regulations (such as GB 50016-2014 "Code for Fire Protection Design of Buildings") or specific design requirements.
