G40 Galvanized Prepainted Steel Coil Ppgi Coated Coil 0.12-2mm Thickness

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.
