First, the fire rating of aluminum veneer is A2 level

The main components of aluminum veneer products are AA1100H24 and AA3003H24 and other high-quality aluminum alloy sheet processing! 1100 is pure aluminum with a content of up to %99.9, while the aluminum content of 3003 is 97% plus %3 of manganese. The melting point of aluminum is 660.4 ° C, and the melting point of additional manganese metal is as high as 1245 ° C, which greatly enhances the structural strength and fire resistance of the board surface. The fluorocarbon baking varnish on the surface of the product is also a high temperature resistant material with a melting point of up to 380 ° C.

Secondly, fireproof materials can be placed in the middle of the aluminum veneer or aluminum curtain wall, and the overall level of [combustion performance classification of building materials and products] GB8624-2006 A2 level.

The comprehensive conclusion is that the fire resistance of aluminum veneers used as decorative objects is close to perfect. Sufficient to meet the fire safety needs of public places.

Second, the description of the fire rating:

Class A: Completely non-combustible building materials.

Class A1: Non-combustible, no open flames.

Class A2: Non-combustible, a small amount of smoke.

Grade B1: The material has a flame retardant effect. It is difficult to catch fire when exposed to an open flame or at a high temperature. After the fire source is removed, the combustion stops immediately.

Grade B2: Combustible building materials: has a certain flame retardant effect. In case of fire or high temperature, it will immediately start to burn.

Class B3: Extremely flammable, the fire is very dangerous.

How high is the fire rating of the curtain wall aluminum veneer?

The fire rating of the aluminum veneer is A2 grade. The main components inside the aluminum veneer are AA1100H24 and AA3003H24, of which 1100 is pure aluminum with a content of up to 99.9%, while the aluminum content of 3003 is 97% plus 3% of manganese, aluminum The melting point is 660.4 ° C, and the additional manganese metal melting point is as high as 1245 ° C, which greatly enhances the strength and fire resistance of the aluminum veneer.

In summary, the fire rating of aluminum veneers is A2 grade, because the raw material of aluminum veneers is metal aluminum, metal aluminum can meet the fire protection requirements of most buildings, and we can also add inside the aluminum veneers. Install some fireproof materials such as rock wool, which can further enhance the fire performance of aluminum veneer materials.
