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 Diagram
Hot Dip Galvanized Steel
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color coated sheet. In addition to the protective effect of hot-dip galvanized sheet, the organic coating on the surface also plays a role of insulation protection and rust prevention, and its service life is longer than that of hot-dip galvanized sheet.
Hot Dip Galvalume Steel
The hot-dip galvalume steel sheet is used as the newly coated substrate, and the corrosion resistance of the hot-dip galvalume steel sheet is 2-5 times that of the hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490 °C will not cause severe oxidation or scale formation. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, which is an ideal building material to save energy.
Electro Galvanized Steel
The electro-galvanized sheet is used as a substrate, and the product obtained by baking with organic coating is an electro-galvanized color-coated sheet. Due to the thin zinc layer of the electro-galvanized sheet, the zinc content is usually 20/20 g/m2, so this product is not suitable for use Make walls, roofs, etc. outdoors. However, because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration and so on.
Coating Type of PPGI & PPGL
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.
Main Features of PPGI & PPGL
1.Good durability and long life compared with galvanized steel.
2.Good heat resistance, less discoloration at high temperature than galvanized steel.
3.Good thermal reflectivity.
4.Processability and spraying performance similar to galvanized steel.
5.Good welding performance.
6.Good performance-price ratio, durable performance and extremely competitive price.
Application of PPGI & PPGL
PPGI & PPGL sheets are widely used in construction, industry, household manufacturing, product packaging, interior decoration and other fields.
