In addition, B1 grade fireproof aluminium composite panel is made of fireproof core material and aluminum composite panel on both sides. According to ASTM E84-08, EN13501-1 testing standards, the fireproof board can reach B1 level, it is a green material, which will not produce toxic gas when burning. It has many properties, wide board surface, good flatness and good processability. Widely used in outdoor buildings, indoor walls, ceilings, columnar exterior decorative panels, bottom panels, signboard panels, advertising panels, furniture and other places.

The difference between Class A and Class B fireproof aluminium composite panel mainly lies in its fireproof grade and performance.

Class A fireproof aluminium composite panel has the highest fireproof grade, and its core material adopts inorganic material, which does not produce toxic smoke when burning and meets the national class A fireproof standard. At the same time, A-class fireproof aluminium composite panel also has good environmental performance and decorative properties, widely used in high-level hotels, hotels, KTV, banks and other places of indoor and outdoor decoration.

Compared with Class A fireproof aluminium composite panel, Class B fireproof aluminum composite panel has a slightly worse fireproof performance, but still has good flame retardant properties, in line with the national fire standards of Class B. Class B fireproof aluminum composite panel has a relatively low price, and it is suitable for places that do not have a high fireproofing requirement, such as offices and shops.
