Prepainted Galvalume Steel Coil(PPGL) is a type of steel product that has been coated with a layer of aluminum-zinc alloy (Galvalume) and then pre-painted with a layer of protective paint.

PPGL Coil uses DX51D+AZ, q195, and galvalume steel sheet as the substrate, PE coating is our most commonly produced, it can be used for up to 10 years. We can also customize the color of the PPGL steel coil, such as wood grain, or matt.
