- Thickness: 0.12 mm-1.20 mm
- Zinc Coating Weight: Z30–Z275 g/m² (both sides)
- Paint Type: PE, SMP, HDP, PVDF
- Steel Grade: DX51D+Z, DX52D+Z, DX53D+Z, SPCC, SPCD, S250GD, S350GD, Q195, Q215, Q235, etc.
1250mm PPGI Coil Structure and Coating Layers
PPGI (Pre-Painted Galvanized Steel) coil is produced from cold-rolled steel through continuous hot-dip galvanizing and coil coating. Its typical structure consists of a steel substrate, zinc coating, chemical conversion layer, primer, and topcoat.
- Steel Substrate: Provides strength and formability.
- Zinc Coating: Protects the steel substrate from corrosion.
- Chemical Conversion Layer: Improves paint adhesion and corrosion protection.
- Primer: Enhances coating adhesion and provides additional corrosion protection.
- Topcoat: Provides color, weather resistance, UV resistance, and surface protection.

PPGI Paint Options and Service Life
PPGI coils are commonly available with four paint systems: PE, SMP, HDP, and PVDF. Each coating type offers different levels of weather resistance, UV resistance, color retention, durability, and typical service life, allowing the coating to be selected according to the application environment and performance requirements.
- PE (Polyester): Good flexibility, color retention, and cost-effectiveness. Typical service life: 5–10 years.
- SMP (Silicone-Modified Polyester): Better weather resistance, gloss retention, and durability than PE. Typical service life: 10–15 years.
- HDP (High-Durability Polyester): Enhanced weather resistance and color retention for outdoor applications. Typical service life: 15–20 years.
- PVDF (Fluorocarbon): Excellent UV resistance, weathering, and color retention for demanding environments. Typical service life: 20+ years.
Surface Finish and Colors
PPGI coils are available in various surface finishes, colors, and decorative patterns. Surface options include glossy, matte, wrinkle, and embossed finishes. Colors can be selected from the RAL color chart or matched to customer samples. Decorative patterns such as marble, brick, floral, striped, tile-like, grass, and sky designs are also available. Wanzhi Group provides customized finishes, colors, and printing options for different project requirements.
