If you are looking for a reliable PPGI steel coil manufacturer in China, you’ve come to the right place. At ChinaCNU Steel New Materials Co., Ltd., we specialize in producing high-quality Pre-Painted Galvanized Iron (PPGI) coils and sheets for customers worldwide.

What is PPGI Steel Coil?

PPGI (Pre-Painted Galvanized Iron) steel coil, also known as color coated galvanized steel coil, is produced by applying organic coatings (polyester, PVDF, SMP) onto hot-dip galvanized steel substrate. It combines the corrosion resistance of galvanized steel with the aesthetic appeal of colored surface treatment.

PPGI vs PPGL: What’s the Difference?

PPGI uses hot-dip galvanized steel (zinc coating) as substrate, while PPGL (Pre-Painted Galvalume) uses Galvalume steel (aluminum-zinc alloy coating). PPGL offers superior heat and corrosion resistance, making it ideal for industrial roofing in harsh environments. Both are available from our factory.
