ChinaCNU Steel is a leading manufacturer and exporter of high-quality DX51D galvanized steel coil from Qingdao, China. This product is a cold-rolled steel coil that has been coated with a protective layer of zinc through a continuous hot-dip galvanizing process, offering excellent corrosion resistance and formability. Primarily conforming to European standard EN 10346, DX51D GI coil is a fundamental material for various manufacturing and construction applications, prized for its smooth surface and consistent coating. Our factory produces DX51D with precise zinc coating weights, including the common DX51D Z100 zinc class, ensuring durability and performance for global buyers.
Our DX51D galvanized steel coils are produced to meet stringent international standards. The table below details the key specifications for our DX51D GI coils, which are central to understanding the product’s capabilities and ensuring it meets your project’s DX51D specs Europe requirements.
| Grade | Standard | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Surface Finish |
|---|---|---|---|---|---|
| DX51D | EN 10346 | 0.15 – 3.0 | 600 – 1500 | Z60 – Z275 (e.g., DX51D Z100) | Regular Spangle, Minimal Spangle, Smooth |
| DX51D+Z | EN 10346 | 0.3 – 2.5 | 800 – 1300 | Z140 – Z200 | Regular Spangle, Minimal Spangle |
We can also supply coils with various surface treatments, such as chromated, oiled, or passivated, upon request. All our DX51D galvanized steel coil production is controlled to ensure precise mechanical properties, including yield strength and elongation, suitable for deep drawing applications.
The versatility of DX51D galvanized steel coil makes it suitable for a wide range of industries. Its excellent corrosion protection and formability are key for:
When sourcing your DX51D GI coil, partnering with a reliable factory is crucial. Here’s why global buyers trust ChinaCNU Steel as their DX51D GI coil factory:
The price for DX51D galvanized steel coil fluctuates based on global raw material costs (zinc, steel), coating weight (e.g., Z100 vs. Z200), dimensions, and order volume. As a factory, we provide transparent FOB Qingdao pricing. For the most accurate and competitive quote tailored to your specific DX51D specs, please contact our sales team with your detailed requirements. We offer free quotes and are committed to helping you find the best value solution for your project.
Both are grades under EN 10346, but DX52D offers improved ductility and is more suitable for severe forming operations compared to DX51D, which is designed for normal forming. The choice depends on the specific forming requirements of your application, such as when manufacturing complex deep drawn components.
The “Z100” refers to the total zinc coating weight on both surfaces of the steel sheet. Specifically, DX51D Z100 means the coil has a minimum total coating mass of 100 grams per square meter (e.g., 50g/m² per side). This is a standard coating class that provides a good balance of corrosion protection and cost for many applications.
Yes, absolutely. Our factory can further process DX51D GI coils into pre-painted galvanized steel (PPGI) by applying color coatings on the galvanized surface. This provides enhanced aesthetics and additional corrosion resistance, making it ideal for architectural building panels and premium appliance exteriors.
We use robust, weather-resistant packaging to protect the coils. Each coil is wrapped with multiple layers of waterproof paper and a final outer cover of steel wrapper or plastic film. They are then securely fixed on wooden pallets or in steel cradles to prevent movement during transit. This method is standard for protecting galvanized steel coil for export and has proven effective for shipments worldwide.
