Sectional
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.

Frequently Asked Questions
Here are the common questions that you may want to know.
Does Pre-painted Galvanized Coil Have a Protective Film?
The protective film is a transparent or colored plastic film coated on the surface of the pre-painted galvanized steel coil. The purpose is to prevent scratches on the painted surface paint during cold roll forming.
Our plastic film thickness is 30 microns, 40 microns, 50 microns, 60 microns, and 80 microns.
Prepainted Galvanized Steel Coil(PPGI Coil) HS Code
The HS Code for prepainted galvanized steel coil(PPGI Coil) with a thickness of <1.5mm and a width of 600mm and above is 721070.
Note: If importing from China, please check the import tariff of your local country.
Price of Pre-painted Galvanized Steel Coils
The price of ppgi coils varies depending on the raw material of steel, the weight of zinc of the galvanized substrate used, the type of coatings used, the thickness of the top coat and back coat, the width and thickness of the steel coil to influence the price.
Paint Thickness
The top finish coating is larger than 20μm to prevent the intrusion of corrosive media. Due to the different anti-corrosion mechanisms of primer and finish coating, not only the total coating thickness should be guaranteed, but also the thickness of primer (>5μm) and finish coating (>15μm).
PVDF pre-painted steel coil requires a thicker coating. It provides a longer service life. The requirements for the backside paint coating depend on the application, and the sandwich panel only requires a layer of primer. The formed steel plate requires two coats. The thickness is at least greater than 10 μm.
