PPGL Prepainted Galvalume Steel Coil
PPGL stands for Pre-Painted Galvalume Steel. The key difference lies in the Galvalume substrate (aluminum-zinc alloy steel). The Galvalume coating is composed of 55% aluminum, 43.4% zinc, and a small amount of silicon. Compared to pure galvanized steel, it offers greater weather resistance and high-temperature oxidation resistance, making it suitable for highly corrosive environments or high-end architectural applications.
The substrate is an annealed cold-rolled steel coil.
Chromated paint is used for cleaning the surface of the cold-rolled coil.
After Chromated, the next is zinc coated. The coil becomes a galvalume steel coil now.
After zinc coated, the next is Chromated again, for cleaning the galvalume steel coil surface again.
The primer coating is used for increasing the adhesion of the top coating. When cold roll forms, the paint will not fall off.
The top paint coating metal is PE or PVDF.

GNEE STEEL can customize the color according to your sample, the following colors are just examples.
