Product Description

Hot Dipped Galvanized Steel Coil has excellent performance, possessing ideal comprehensive properties of corrosion resistance, formation and coating. It is produced by passing the steel sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristic.


Galvanized steel (GI) are mainly used in building, automobiles, metallurgy, electric equipments and more.

  • Building – roof, door, window, roller shutter door and suspended skeleton

  • Automobiles – vehicle shell, chassis, door, trunk lid, oil tank, and fender

  • Metallurgy – steel sash blank and color coated substrate

  • Electric equipements – refrigerator base and shell, freezer, and kitchen equipment

What Are the Benefits of Hot Dipped Galvanized Steel Coils?



As mentioned, galvanized steel coils are a cost-effective solution for many industrial applications, but cost is only one of many benefits. Sinowell Metal produces hot dipped galvanized steel coils that are:

  • Durability. Hot dipped galvanized steel products enjoy a long life expectancy. It’s not uncommon for products to last more than fifty years in some applications. Even with exposure to weather or other environmental conditions, hot dip galvanized steel coils are designed with longevity in mind. Their corrosion-resistant properties enable them to function optimally for decades.

  • Strength. When it comes to toughness, hot dipped galvanized steel metal coils are dependably strong. The metallurgical relationship between zinc and steel makes for outstanding strength as well as durability.

  • Practical. Sinowell Metal galvanized steel products will arrive ready for use, making them an incredibly practical solution for today’s industries. Our products will arrive requiring no additional treatments or testing. You can introduce our galvanized steel right to your line.

  • Reliable. Since Sinowell Metal produces hot dipped galvanized steel coils to meet the most stringent ASTM standards and other applicable certifications, our customers can rely on their performance. Sinowell Metal has built its reputation on its professionalism and high-quality production; we stand behind our reliable galvanized steel products.
