Hot Dip Galvanized Steel Coil, commonly referred to as HDG coil, is a premium steel product where a base steel coil is submerged in a bath of molten zinc to create a robust, corrosion-resistant coating. This process, known as hot-dip galvanizing, provides superior protection against rust and environmental damage, making it a fundamental material for demanding construction and industrial applications. At ChinaCNU Steel, with over 15 years of expertise, we specialize in exporting high-quality hot dip zinc steel coil from our factory in Qingdao to global markets.
Our HDG coils are manufactured to meet international standards, offering a range of specifications to suit diverse project requirements. The table below details our standard product parameters.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, DX52D, DX53D | 0.12 – 3.0 | 600 – 1500 | 60 – 275 | EN 10346, ASTM A653 |
| SGCC, SGCH | 0.15 – 2.5 | 700 – 1250 | 80 – 220 | JIS G 3302 |
| Q195, Q235 | 0.25 – 4.0 | 800 – 1500 | 100 – 250 | GB/T 2518 |
Note: Custom specifications for DX51D galvanized and other grades are available upon request.
The exceptional durability and corrosion resistance of hot dip galvanized steel coil make it suitable for a vast array of industries. Key applications include:

Pricing for hot dip zinc steel coil is influenced by factors such as raw material costs (zinc and steel), coil specifications, and international market trends. We offer transparent FOB Qingdao pricing, providing you with a clear cost basis for your logistics. For the most accurate and competitive factory price for your specific HDG coil requirements, we provide a free, no-obligation quote tailored to your project’s grade, dimensions, and volume.
Hot-dip galvanized (HDG) coil involves immersing steel in molten zinc, creating a thicker, metallurgically bonded coating ideal for outdoor and high-corrosion environments. Electro-galvanizing uses an electrical process to apply a thinner, smoother zinc layer, often used for aesthetic applications. For structural durability, hot dip galvanized steel coil is the superior choice.
DX51D is a common European standard grade (EN 10346) for hot-dip galvanized steel. It signifies a steel grade suitable for forming, with a minimum yield strength, designed for direct use where the zinc coating provides the primary corrosion protection. DX51D galvanized coil is widely used in construction and general manufacturing.
From our Qingdao factory, the total lead time—including production and shipping—typically ranges from 15 to 25 days. The exact timeline for shipping HDG coil to Africa or the Middle East depends on the destination port and current vessel schedules, which we manage efficiently based on our extensive export experience.
We support secure international payment methods, primarily by T/T (Telegraphic Transfer) and L/C (Letter of Credit). Terms are confirmed with your formal quote and purchase order, ensuring a smooth and trustworthy transaction for buyers worldwide.
