From the material distinction, fire rated doors can be divided into steel fire doors and wooden fire doors, and from the perspective of practical application, fire doors can also be divided into normally closed fire doors and fire rated emergency exit doors.

Public places with a load of people like shopping centers and movie theaters are where most of this type of doors are used in.

A. Push Panic Crossbar
B. Panic Bar
C. Vertical Rod Panic Bar
