Understanding precise PPGI coil specifications is critical for sourcing the correct pre-painted galvanized iron for your construction or manufacturing project. This page details the exact technical parameters—including PPGI thickness, width, zinc coating, and grade standards—to help you make an informed procurement decision. ChinaCNU Steel, with over 15 years of expertise, manufactures and exports high-quality PPGI coils from our Qingdao factory, ensuring every product meets rigorous international specifications for durability and performance.
Our PPGI coils are manufactured to exacting standards, combining a galvanized steel substrate with a durable painted finish. The specifications below define our standard production range, which can be customized to meet specific project requirements. Refer to this detailed PPGI specs table for key technical data.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, DX52D, DX53D | 0.12 – 1.2 | 600 – 1250 | 60 – 275 | EN 10346, ASTM A755, JIS G3302 |
| S280GD, S350GD | 0.3 – 1.5 | 800 – 1250 | 100 – 180 | EN 10346 |
| SGCC, SGCH | 0.13 – 0.8 | 700 – 1200 | 60 – 120 | JIS G3302 |
Note: The PPGI grade standard determines formability and strength, while the PPGI thickness and width define the physical dimensions. The PPGI zinc coating weight is crucial for underlying corrosion resistance.
PPGI coils are valued across industries for their corrosion resistance, aesthetic appeal, and structural integrity. Key applications include:
Selecting ChinaCNU Steel as your PPGI supplier ensures reliability, quality, and seamless service from inquiry to delivery.
PPGI coil pricing is dynamic and depends directly on the specifications you require—primarily steel grade, dimensions, zinc coating weight, and paint system. As a factory, we offer highly competitive FOB Qingdao prices. For the most accurate and current quote tailored to your project’s PPGI thickness, width, and coating, please contact us with your detailed requirements. We provide free, no-obligation quotations within 24 hours.
While both start with a galvanized substrate, PPGI coil specifications include additional parameters for the paint system—such as paint type (PVDF, HDP, SMP), film thickness, and color retention—on top of the standard GI specs for base metal and zinc coating. PPGI offers enhanced corrosion protection and aesthetic options.
The required PPGI zinc coating weight depends on the environmental corrosivity. For standard building cladding, 100-120 g/m² is common. For more aggressive coastal or industrial environments, a heavier coating of 180 g/m² or higher is recommended to ensure long-term durability of the steel substrate beneath the paint.
Yes, as a manufacturer, we specialize in customizing PPGI thickness and width. While our standard range is listed, we can slit coils to specific narrow widths or produce to unique thickness tolerances upon request, subject to feasibility and order volume.
Our PPGI is produced to meet major international standards that define the mechanical properties and coating requirements. Common standards include EN 10346 (Europe), ASTM A755 (USA), and JIS G3302 (Japan). The specific grade (e.g., DX51D, S350GD) within these standards defines the yield strength and formability.
