Prepainted Galvalume Steel Coil (PPGL)
High-Performance PPGL Coils with Custom Colors and Long-Lasting Protection from Hengze Steel
Prepainted Galvalume Steel Coil (PPGL) Manufacturer
Hengze Steel is a trusted manufacturer of high-performance Prepainted Galvalume Steel Coil (PPGL), engineered for superior corrosion resistance and long-lasting color retention. Our PPGL coils are widely used in roofing, wall cladding, and other demanding construction applications.
PPGL combines the durability of galvalume substrate (55% aluminum, 43.4% zinc, 1.6% silicon) with a high-quality paint finish. This advanced coating system provides enhanced protection against harsh weather, UV exposure, and chemical corrosion, significantly outperforming standard galvanized steel.
We use premium-grade materials like DX51D+AZ and Q195 for base metals, with PE (polyester) coating being the most cost-effective and commonly used option, offering up to 10 years of service life. For customers requiring higher durability, we also offer SMP and PVDF coatings.
At Hengze, we support custom surface designs such as wood grain, matte finishes, and custom RAL colors, allowing your projects to combine functionality with visual appeal.
Our PPGL coils are tested according to international quality standards, and we provide SGS-certified reports and support third-party factory inspections to ensure product consistency and performance.
