Color Coated Prepainted Galvanized Steel Customized Colour For Roofing Panels
Buy high-quality PPGI steel coil for roofing sheets, wall panels, and appliances. Durable color coating, strong corrosion resistance, and custom specifications. Fast delivery from factory.
PPGI steel coil is a prepainted galvanized steel product designed to provide both structural strength and long-term surface protection. By applying multi-layer organic coatings on zinc-coated steel, PPGI delivers enhanced corrosion resistance, weather durability, and decorative performance.
Unlike bare galvanized steel, PPGI eliminates the need for additional painting processes, saving both labor and time for end users. It is especially suitable for roofing and wall systems where long service life, stable color performance, and easy installation are required.

PPGI stands for Prepainted Galvanized Iron. It is a coated steel product made by painting galvanized steel, offering both corrosion protection and decorative appearance.
PPGI uses galvanized steel (zinc coating), while PPGL uses galvalume steel (aluminum-zinc coating). PPGL generally provides better corrosion resistance, while PPGI is more cost-effective.
The lifespan depends on the coating type and environment:
- PE: 8–10 years
- SMP: 10–15 years
- PVDF: 20+ years
Yes, we offer full customization including:
- RAL color matching
- Thickness & width
- Coating thickness
- Surface finish
Yes, PPGI is widely used for roofing sheets due to its durability, corrosion resistance, and aesthetic appearance.
