The prepainted steel sheet in coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, and galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating), followed by baking and curing.
The total thickness of the pre-panted galvanized steel coil is composed of the base steel - coating -primer - top paint protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.

PPGI coil is a popular material. It is based on hot-dip galvanized steel sheet or electro-galvanized steel sheet (galvanized layer) and is coated with multiple organic coatings to prevent it from rusting.

Color-coated galvanized sheet PPGL uses hot-dip galvanized sheet, electro-galvanized sheet as the substrate. It is coated with one or more layers of liquid coating after surface pretreatment and roller coating method. After baking and cooling, the surface has good weather resistance, superior processing performance and is rich in colors.

PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting.
