PPGL
Product Introduction
| Item | Specification |
|---|---|
| Product Name | Pre-painted Galvalume Steel (PPGL) |
| Base Metal | Low-carbon cold-rolled steel (Typical grade: DX51D, DX52D, or ASTM A1008) |
| Core Coating Type | 55% Al-Zn alloy coating (Galvalume, per EN 10346 / ASTM A792) |
| Standard Compliance | EN 10169 (Europe), ASTM A755 (North America), GB/T 12754 (China) |
| Typical Thickness Range | 0.25 mm – 1.2 mm (base metal + coatings) |
| Element | Symbol | Content (Maximum / Typical, wt%) | Remarks |
|---|---|---|---|
| Carbon | C | ≤ 0.12% | Reduces brittleness; ensures ductility |
| Manganese | Mn | ≤ 0.50% | Improves strength without excessive hardening |
| Silicon | Si | ≤ 0.05% | Minimizes surface defects in coating |
| Phosphorus | P | ≤ 0.025% | Controls corrosion sensitivity; avoids embrittlement |
| Sulfur | S | ≤ 0.025% | Reduces hot cracking risk during processing |
| Aluminum | Al | 0.02% – 0.06% | Deoxidizes molten steel; refines grain structure |
| Iron | Fe | Balance | Main matrix component of the base steel |
| Property | Test Standard | Unit | Typical Value (DX51D) | Typical Value (DX52D/ASTM A1008) |
|---|---|---|---|---|
