🟧 Product Overview

PPGI (Prepainted Galvanized Steel Coil) is produced by applying one or more layers of organic paint onto a galvanized steel substrate through continuous coil‑coating technology. The combination of zinc protection + organic coating provides:

• Excellent corrosion resistance
• Long‑lasting color durability
• Superior formability and processing performance
• Decorative appearance suitable for architectural and industrial use

PPGI is widely used in construction, roofing, wall cladding, home appliances, and transportation.
