Fire doors are very important in our public places, because they not only ensure our safety, but also effectively eliminate potential fire hazards. What is the classification of fire doors? Today we will learn about the classification of fire doors

fire doors are very important in our public places, because they not only ensure our safety, but also effectively eliminate potential fire hazards. What is the classification of fire doors? Today we will learn about the classification of fire doors

classification of fire doors 1. According to the classification of thermal insulation fire doors

class a fire doors: also known as thermal insulation fire doors, they can meet the requirements and fire-resistant materials at the same time within the specified time, and maintain integrity. The fire resistance rating is 0.5 h (Class C), 1.0 (b), 1.5 h (a) and 2.0 h, 3.0 H

class B fire door: also known as a part of heat insulation fire door, the fire resistance and heat insulation requirements are 0.5 h, and the fire integrity rating is 1.0 - 1.5 h, h, h, 2.0 to 3.0 H

class C fire door: also known as thermal insulation fire door, there is no requirement for fire resistance and heat insulation. Within the specified time, the refractory material can only meet the requirements of fire resistance integrity, and the integrity fire resistance rating is 1.0 - 1.5 h, h, h, 2.0 - 3.0 H

classification of fire doors 2. Fire resistance time of fire doors

thermal insulation fire doors (Class A) thermal insulation refractory materials maintain a sensitivity of 0.50 h fire integrity ≥ 0.50 ha0.50 (Class C) thermal insulation refractory maintains sensitivity 1.00 h fire resistance integrity ≥ 1.00 ha1.00 (class B) thermal insulation refractory maintains sensitivity 1.50 h fire resistance integrity ≥ 1.50 ha1.50 (Class A) thermal insulation refractory maintains sensitivity 2.00 h fire integrity ha2.00 2.00 or higher thermal insulation refractory maintains sensitivity 3.00 h fire integrity ha3.00 3.00 or higher

insulated fire door (b) ≥ 0.50 h fire resistant insulation refractory materials maintain integrity hb1.00 1.00 or higher fire resistance integrity hb1.50 1.50 or higher fire resistance integrity hb2.00 2.00 or higher fire resistance integrity hb3.00 3.00 or higher

insulated fire door (c) fire integrity hc1.00 1.00 or higher fire integrity hc1.50 1.50 or higher fire integrity hc2.00 2.00 or higher fire integrity hc3.00 or higher

I'll introduce the classification of fire doors here. I hope it can help you. More decoration information is available. Please look forward to it
