Product Description The prepainted steel plate 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. Unrolling → Stitching machine → Entrance loop → Pretreatment → Initial coating → Bake → Cool down → Fine coating → Bake → Embossed film → Export loop → Inspection station → Cut → Coiling 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. * Usually, the paint coating material is polyester (PE) and the color of the back paint is white grey.
