PPGI Coils — Versatile and Colorful Steel Solutions

Jun. 25, 2025
Share

PPGI (Pre-Painted Galvanized Iron) coil is a high-quality steel product produced by coating steel sheets with one or more layers of organic paint, followed by high-temperature baking to cure the coating. The base materials commonly include hot-dip galvanized sheets, hot-dip aluminum-zinc sheets, and electro-galvanized sheets. The applied coatings provide excellent corrosion resistance, aesthetic appeal, and superior workability.
