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.
COSASTEEL 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.

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.
Superior Durability: Our prepainted galvanized steel coil is designed to withstand the conditions. The galvanization process ensures exceptional resistance to corrosion, while the high-quality paint coating provides an extra layer of protection against the elements.
Wide Range of Uses: Whether you are in the construction or cold storage industry, our steel coils are the perfect solution for a wide range of applications.
Aesthetic Appeal: Available in a variety of colors and finishes, our prepainted galvanized steel coil allows you to achieve the perfect look for your project. The vibrant, long-lasting colors ensure that your products not only perform well but also look stunning.

Here are the common questions that you may want to know.
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.
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.
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.
Choosing PPGI coils needs to consider the natural environment, use environment, design life, and structural characteristics of the building to match the appropriate steel grade, specifications, Metallic coating, and coating.
The performance of PPGI coil mainly includes the mechanical properties of the material (tensile strength, yield strength, elongation), Metallic coating performance (Metallic coating type, thickness, and adhesion), and coating performance (coating species, color, gloss, durability, Processability, etc.)
The main consideration for the selection of pre-painted galvanized steel coils in different regions is the local wind and snow load and corrosive environment.
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.
