ASTM Standard PPGI Coil for Roof Panels
ASTM A755 prepainted galvanized steel coil is manufactured for commercial roof panel production with reliable coating performance and dimensional stability. The Z180 zinc coating provides additional corrosion resistance, while the painted surface enhances durability and appearance. It is commonly used in commercial buildings, industrial facilities, warehouses, and architectural roofing systems.
What Is PPGI？
Product Definition：
PPGI (Pre-painted Galvanized Steel Coil) is a high-performance composite material manufactured by applying a durable organic paint system onto a galvanized steel substrate in a continuous coil-coating line-. The substrate is made of cold-rolled steel sheet that has been hot-dip galvanized with a layer of zinc to provide corrosion resistance-. After surface pretreatment (degreasing, cleaning, chemical conversion), a primer and topcoat are applied and cured, resulting in a product that combines the strength of steel with the aesthetics of paint-.
Key Characteristics：
| Feature | Description |
|---|---|
| Corrosion Resistance | Zinc coating (40-275 g/m²) provides sacrificial protection to the steel base- |
| Aesthetic Versatility | Available in a wide range of RAL colors, gloss levels, and decorative finishes (wood grain, embossed) |
| Durability | Paint systems (PE, SMP, HDP, PVDF) offer excellent weathering, UV, and chemical resistance- |
| Formability | Can be roll-formed, stamped, bent, and deep-drawn without damaging the coating |
| Cost-Effective | Eliminates the need for post-fabrication painting, reducing production time and cost |
| Lightweight & High Strength | Combines structural strength with low weight, reducing transportation and installation costs |
| 100% Recyclable | Environmentally friendly material with excellent recyclability |
Why Choose PPGI Over Bare Steel or Post-Painted Steel？
| Factor | PPGI | Bare Steel | Post-Painted Steel |
|---|---|---|---|
| Corrosion Resistance | Excellent (zinc + paint) | Poor | Good |
| Aesthetic Consistency | Excellent (factory-controlled) | N/A | Variable |
| Production Efficiency | High (ready-to-use) | Low (requires painting) | Medium |
| Long-Term Cost | Lower (no repainting) | High (frequent maintenance) | Medium |
