The taxonomy of basic steel plate for color coating.

1. Cold-rolled color coated board. The color plate produced from the cold-rolled substrate has a smooth and beautiful appearance, and has the processing performance of the cold-rolled plate; however, any fine-scaled drawing of the surface coating exposes the cold-rolled substrate to the air, so that the rust is generated at the exposed iron quickly. . Therefore, these products can only be used for indoor materials.

2.Hot-dip prepainted galvanized steel(PPGI). The product obtained by coating the organic paint on the hot dip galvanized steel sheet is a hot dip galvanized coated sheet. Hot-dip galvanized steel coated plate has the protective effect of zinc, the organic coating on the surface also plays the role of insulation protection and rust prevention, and the service life is longer than that of hot-dip galvanized sheet.

3.Prepainted galvalume steel(PPGL), according to the requirements, can also be used as hot-dip galvanized steel coated substrate.
