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. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print,camouflage, brick.

Service life(years)

1)  Epoxy primer, good adhesion, water resistance, alkali resistance, chemical corrosion resistance, poor single toughness.
2)  Polyester primer, good adhesion, good flexibility, sensitive to humid environment, chemical resistance is not as good as epoxy primer.
3)  Acrylic primer, good adhesion, good toughness and high pretreatment requirements.
4)  polyurethane primer, chemical resistance, abrasion resistance, durability, toughness

1)  Polyester resin, good adhesion, molding and outdoor durability.
