Pre-Painted Galvanized Iron Steel Coils
Products Description
PPGI (Pre-Painted Galvanized Iron) Steel Coils represent the premium category of coated steel products, combining the corrosion resistance of galvanized steel with the aesthetic appeal and additional protection of factory-applied paint coatings. These coils are manufactured through continuous coil coating lines that apply multiple layers of protection and color in a precisely controlled environment, ensuring consistent quality and performance.

Frequently Asked Questions
Q: What's the difference between PPGI and PPGL?
A: PPGI uses galvanized steel (zinc coating) as base, while PPGL uses galvalume (aluminum-zinc alloy coating). PPGL offers better corrosion resistance at cut edges.
Q: Can PPGI coils be used for outdoor applications?
A: Absolutely. With proper paint system selection (PVDF or HDP recommended), PPGI performs excellently outdoors with 15-30 year lifespans.
Q: What is the minimum order quantity?
A: Standard colors: 20 tons. Custom colors: 50 tons. Sample coils available for testing.
Q: How accurate is the color matching?
A: We achieve ΔE<1.0 for standard colors, ΔE<1.5 for custom matches using spectrophotometer control.
Q: Can you produce special widths or thicknesses?
A: Yes, we offer custom slitting and can produce special thicknesses with minimum order quantities.
