Prepainted Galvanized Steel Coil (PPGI)

 

Our Prepainted Galvanized Steel Coil(PPGI) – the ultimate solution for durability, aesthetics, and versatility. Engineered to perfection, our steel coils are coated with top-quality paint, ensuring long-lasting color retention and superior corrosion resistance.

 

GNEE STEEL is a prepainted steel coil manufacturer. Direct purchase from the factory is cheaper than traders. We can accept factory inspection and SGS inspection reports of steel coils.

 

Prepainted Galvanized Steel Coil is a paint applied to the surface of the steel coil after it has been galvanized. Such coatings include polyester, silicon-modified polyester, polyvinylidene fluoride (PVDF), etc. This coating not only adds color and aesthetic appeal but also provides an extra layer of protection.

Thickness Range: 0.2mm to 1.2mm
Width Range: 600mm to 1250mm
Coating: Zinc coating ranging from 60g/m to 275g/m
Paint System: Polyester, SMP, PVDF
Color Options: RAL color chart available for custom color matching
Paint Thickness Top paint:10-30mic, Back paint: 5-25 mic
Surface Finish: Glossy, matte, or textured

Sectional

Prepainted Galvanized Steel Coil (PPGI)

Base Metal (Galvanized Steel): The core of the coil is galvanized steel, which is steel coated with a layer of zinc to provide corrosion resistance.

Chemical Treatment Layer: This layer is applied to the galvanized steel to improve adhesion of the subsequent coatings and to enhance corrosion resistance.

Primer Coating: A primer coating is applied on top of the chemical treatment layer. This layer further enhances adhesion and provides an additional barrier against corrosion.

Topcoat (Finish Coat): The topcoat is a colored paint layer that provides both aesthetic appeal and additional protection.

Back Coat (Optional): On the underside of the coil, a back coat may be applied.
