Using Hot Galvanized Steel Coil as the substrate, color coated steel coil is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used including polyester, silicon modified polyester, high-durability, corrosion-resistance and formability.
Color coated steel coil/sheet (PPGI & PPGL) is widely used in:
Home Appliances, such as the side door plate of refrigerators, shell of DVDs, air conditioners and washing machines.
We are a PPGI & PPGL manufacturer/supplier in Shandong, China. Our PPGI (Prepainted Galvanized Steel) & PPGL (Prepainted Galvalume Steel) are available in a variety of specifications.
We could also provide the product life length lasts for decades as customers commanded.
Class G-90 (Z-275) for galvanized; Class G-60 (Z-180) can be used for pre-painted although G-90 (Z-275) is preferred
