First of all, compare the materials used. The fire door has a simple structure and is mainly composed of four parts: the door closer, the material of the door panel (there are 06 and 08, etc.), the door frame material, and the fireproof panel. Class A fire doors are generally made of 08 material with better quality. The normal service life is 5-8 years. The iron material of the door panel is thicker. For fire doors of the same thickness, the weight of class A fire doors is greater than that of class B fire doors.
