Pre-painted G40 Galvanized Steel Coil Zibo Ppgi Steel Coil Prepainted Steel
Prepainted galvanized steel coil is a kind of color coated steel coil (PPGI coil). It uses
galvanized steel as the base metal. The zinc layer offers strong corrosion resistance. P
-lus with painting, it is more durable than galvanized steel.
Key properties
♦ Corrosion Resistance
Base metal (GI/GL) provides rust protection, while the organic coating adds an extra barrier.
Service life: 10–30 years (depending on environment and coating type).
♦ Aesthetic Flexibility
Available in various colors (RAL, Pantone), gloss levels (high-gloss/matte), and textures (wood
grain, stone effect).
♦ Formability
Can be cut, bent, and stamped, but coating flexibility varies (PVDF resists cracking better than
polyester).
♦ Weather Resistance
High-quality coatings (e.g., PVDF) resist UV fading, chalking, and chemical exposure.
♦ Eco-Friendliness
Some coatings use chromium-free or water-based formulas.
Key Advantages
✅ Cost-Effective – Factory-applied coating reduces on-site painting costs.
✅ Lightweight – Lighter than concrete/stone, ideal for large-span structures.
✅ Quick Installation – Pre-fabricated panels speed up construction.
✅ Low Maintenance – Smooth surface enables self-cleaning with rainwater.
✅ Multifunctional – Can be combined with insulation (sandwich panels) for thermal/acoustic benefits.
Common Thickness & Applications
