How does the aluminum board fireproof?

Aluminum veneers are currently mainstream products in the curtain wall market, and a large number of users use aluminum veneers at the same time. Manufacturers should also pay attention to the quality of aluminum veneer products, especially in response to fire performance.

Aluminium veneers cannot be burned. This is what everyone knows. So if you consider the factors of fire, aluminum single board performance is still very good. However, the fire rating of aluminum veneers is also divided. Normally, the fire ratings of aluminum veneers are all A2 grades. As long as the melting point of aluminum is not exceeded, the varnish on the surface of the aluminum veneer will not be damaged. Therefore, the fire performance of aluminum veneers is very high.

The main reason for the poor fire performance of aluminum veneers is that some unscrupulous merchants produce products that are too thin and use inferior paint, which has a great impact on the fire performance of aluminum veneers.

Explanation of fire rating:

Grade A: Completely incombustible building materials.

Class A1: Not flammable, no open flame.

A2 level: non-combustible, small amount of smoke.

Level B1: The material has a flame retardant effect, and it is difficult to catch fire in the event of a fire or at a high temperature. After the fire source is removed, the combustion stops immediately.

B2 level: flammable building materials: a certain degree of flame retardant effect. In the event of a fire or burning at high temperatures, it will immediately start burning.

Class B3: Extremely flammable, with a high risk of fire.
