PPGL
From top to bottom, it consists of the top coating layer, primer coating, pre-treatment coating, Al -Zn coating, base metal, Al-Zn coating, pre-treatment coating, primer coating, and top coating. The base metal is the most inner part, which often uses cold rolled steel, which is covered with Al-Zn coating. This is the GL sheet. Then PG sheets will be cleaned and degreased to form a layer of passivated metal chromate on the surface, which makes it easy to paint. A primer is a preparatory coating on materials to ensure better adhesion and also provide additional protection. While the finish coat makes the surface smooth and good-looking. Generally, the top coating is thicker than the back coating.
