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.

Prepainted Galvanized Steel Features:

(1) It has good durability and corrosion resistance compared with galvanized steel sheets;
(2) It has good heat resistance and is less prone to discoloration at high temperatures compared to galvanized steel sheets;
(3) has good heat reflectivity;
(4) It has similar processing properties and spraying performance as galvanized steel sheets;
(5) Has good welding performance.
(6) It has good performance and price ratio, durable performance and very competitive price.
