Zinc coated steel coil, also known as galvanized steel coil, is a fundamental material in modern construction and manufacturing. This product consists of a carbon steel coil that has been coated with a protective layer of zinc through a continuous hot-dip galvanizing process. This zinc coating acts as a sacrificial anode, providing exceptional corrosion resistance and significantly extending the service life of the steel. At ChinaCNU Steel, a premier zinc plated steel coil factory in Qingdao, we produce high-quality zinc steel coils for a global clientele, ensuring durability, reliability, and cost-effectiveness for demanding industrial applications.
Our zinc coated steel coils are manufactured to meet precise international standards and customer specifications. Below is a detailed overview of our standard product range. Custom specifications for grade, coating weight, and dimensions are available upon request.
| 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, SGC400 | 0.25 – 4.0 | 800 – 1600 | 100 – 350 | GB/T 2518 |
The versatility of galvanized zinc coated steel makes it indispensable across numerous sectors. Its primary benefit is rust prevention in harsh environments.
Selecting the right supplier for your zinc plated steel coil is critical. Here’s why global buyers trust ChinaCNU Steel.
For our zinc coated steel coil (GI) and color coated PPGI coils, we offer highly competitive FOB Qingdao pricing. The final cost depends on several factors including current raw material prices, zinc coating weight, steel grade, dimensions, and order volume. We provide transparent pricing and are committed to delivering the best value. Contact us today for a free, no-obligation quote tailored to your specific project requirements.
GI (Galvanized Iron) refers to the base zinc coated steel coil with a silver-gray zinc surface. PPGI (Pre-Painted Galvanized Iron) is a GI coil that has undergone an additional process where a layer of paint or laminate is applied, providing both corrosion resistance and an aesthetic color finish. This makes PPGI ideal for applications like architectural roofing where color is important.
For bulk orders, we commonly accept T/T (Telegraphic Transfer) and L/C (Letter of Credit). Payment terms are typically 30% deposit with order confirmation and 70% balance against copy of Bill of Lading, ensuring security and trust for both parties in international steel trade.
The required zinc coating weight, measured in grams per square meter (g/m²), depends on the environmental severity. For interior or mild environments, 60-120 g/m² may suffice. For outdoor construction or industrial atmospheres, we recommend 140-275 g/m² or higher. Our technical team can advise on the best specification for your specific application and location.
