Prepainted steel coil, also known as PPGI coil or color coated steel, is a high-performance building material manufactured by applying a continuous layer of paint and protective coatings over a galvanized steel substrate. This process, performed by a professional painted galvanized coil manufacturer, creates a product with superior durability, corrosion resistance, and aesthetic appeal. At ChinaCNU Steel, we produce premium prepainted steel coils in a wide array of colors and finishes, engineered for long-lasting performance in demanding architectural and industrial applications. Our coils combine the strength of steel with vibrant, protective coatings to meet global project specifications.
Our prepainted steel coils are manufactured to exacting standards, offering versatility for various project requirements. Below are the standard specifications we offer, with customizations available upon request.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, DX52D, DX53D | 0.12 – 1.2 | 600 – 1250 | 60 – 275 | ASTM A755, EN 10169, JIS G 3302 |
| S280GD, S350GD | 0.3 – 1.0 | 800 – 1200 | 100 – 180 | EN 10169 |
| SGCC, SGCH | 0.15 – 0.8 | 610 – 1220 | 60 – 120 | JIS G 3302 |

GI coil (Galvanized Iron coil) is a steel coil coated with a layer of zinc for corrosion protection. PPGI coil (Prepainted Galvanized Iron coil) takes this a step further; it is a galvanized steel coil that has subsequently been painted with a colored coating system. This adds aesthetic value, additional corrosion resistance, and specific functional properties like scratch resistance or heat reflectivity, making it a finished product ready for fabrication.
We offer standard paint systems including Polyester (PE), Silicon Modified Polyester (SMP), and Polyvinylidene Fluoride (PVDF). These come in a vast range of standard colors from the RAL color chart. Custom colors can also be matched for large-volume projects. The choice of paint system depends on the required durability and environmental exposure of the final application.
For standard specifications, our typical production and preparation lead time is between 15 to 25 days after order confirmation and receipt of payment. This timeframe includes production, quality inspection, and packing. The exact lead time will be confirmed with your order based on the current production schedule and the specific requirements of your painted galvanized coil.
To ensure our PPGI coils arrive in perfect condition, we use a multi-layer packing method. Each coil is wrapped with waterproof craft paper, then protected with steel or plastic end caps and side protectors. They are then securely strapped to a wooden pallet or placed inside a reinforced wooden crate. This packing is designed to withstand the rigors of long-distance ocean freight and handling.
