Product Conformation | |
Our fire-resistant aluminum composite panel is made of fireproof plastic core with two layers of aluminum sheets. It is one kind of new decorative material. Thanks to the fireproof elements we add, its fireproof feature can reach Class B1 grade with the test of GB8624, which means it is hard to be fired. It is green material, as there is no harmful gas is produced during burning. |
