PPGI & PPGL (prepainted galvanized steel & prepainted galvalume steel) also known as pre-coated steel or color coated steel coil,It is a product made of hot-dip galvanized steel sheet, hot-dip galvalume steel sheet, electro galvanized steel sheet, etc. After surface pretreatment, one or several layers of organic coating are applied on the surface, and then baked and solidified. The color coated steel coil is light in weight, beautiful in appearance, and has good anti-corrosion performance, and can be directly processed. The color is generally divided into gray, sea blue, brick red, etc. It is mainly used in advertising, construction,decoration, home appliances, electrical appliances, Furniture industry and transportation industry. The coatings used for color coated steel coils are based on the environment in which the resin is selected, such as polyester silicon modified polyester,polyvinyl chloride plastisol, polyvinylidene chloride, and the like.
The coating of the color-coated steel sheet not only protects but also increases the decoration, and the color is
durable and not easy to fade. The surface of different types of color-coated boards can also be embossed and
printed with different types of colors and surface structures.
Color-coated steel sheet also has a very advantageous advantage in terms of architecture and interior decoration,
which can play a role in fire prevention. The coating surface can maintain gloss even under high temperature baking,
and there is no change in surface color.
In terms of processing, the surface coating of high-quality color-coated steel sheets does not fall off after bending or stamping, and the coating quality is far more uniform, more stable, and more ideal than single-body spraying on the
