Fire rating of aluminum-plastic panels

Sep 10, 2021

Fireproof aluminum-plastic composite panels are classified as B1: refractory building materials



Here is the Classification of combustion performance of fireproof materials.

Class A: Noncombustible building materials: materials that have little or no combustion.


ClassB1: non-combustible building materials: non-combustible materials have good flame retardant effect.It is difficult to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly, and the combustion stops immediately after the fire source is removed.


ClassB2: combustible building materials: combustible materials have a certain flame retardant effect.Open fire in the air or under the action of high temperature will immediately catch fire, easy to lead to the spread of fire, such as wooden columns, wooden frames, wooden beams, wooden stairs, etc..


B3类:易燃成矿ding materials: no flame retardant effect, easy to burn, great fire risk.
