PPGL steel coil starts with galvalume substrate. After chemical degreasing and surface conversion treatment, it receives one or more layers of organic coating, followed by baking and curing. The organic film not only adds protection to the existing alu-zinc layer but also seals the surface against corrosion. As a result, PPGL offers approximately 50% longer service life than standard galvalume steel coil.
We continuously refine our manufacturing processes and service quality, while investing actively in R&D for premium PPGI, PPGL, and GI/GL coils. Our business philosophy is "superior quality at fair prices." For inquiries on wholesale prepainted galvalume coils, please reach out.

Lightweight, attractive, and rust-resistant, the Color Coated Steel Coil (including Gi Gl PPGI) is ready for direct forming. Its organic coating works together with the underlying zinc layer to prevent corrosion more effectively — offering roughly 1.5 times the service life of conventional galvanized strip.
PPGL steel coil finds broad use across advertising, construction, home appliances, electrical equipment, furniture, and transportation. The coating system—selected from options like polyester, silicon-modified polyester, PVC plastisol, or PVDF—varies according to the intended service environment, allowing users to match performance to application needs.
Our company is committed to continuous product and service enhancement. We actively invest in R&D for premium China-made prepainted galvalume coils, including PPGL and GI/GL PPGI products. We operate on the principle of “good quality at fair prices.” For wholesale discounts on color coated zinc-aluminium sheets, please contact us. We look forward to a successful partnership and a brighter future together.
