Product Description

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. Top paint: 10-25μm, back paint: 5-20μm.
Paint materials include polyester (PE) with customizable colors (RAL card) and special patterns like wood grain, flower print, or camouflage.
PPGI: Prepainted galvanized steel coil with a hot dip zinc coated substrate.
PPGL: Prepainted galvalume steel coil with a galvalume steel sheet substrate.
