The prepainted steel sheet in coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, an galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating) or a composite organic film (such as a PVC film), followed by baking and curing.

1) PPGI also known as prepainted galvanized steel coil and color coated steel coil, with a hot dip zinc coated steel sheet substrate.

2) PPGL also known as prepainted galvalume steel coil, with a galvalume steel sheet as a substrate.
