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.

Production Process

Substrate Type

1.Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)

The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet;

2.Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)

Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn);

3.Electroplated zinc color coated sheet

The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.

Coating Type

Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost.

Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.

High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.

Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and high cost.

Application of PPGI & PPGL

Color-coated steel sheets are widely used in construction, industry, household manufacturing, product packaging, interior decoration and other fields.
