What Is Galvanized Steel Coil?

Galvanized steel coil is the hot-selling product at Wanzhi Steel. Wanzhi Steel is a famous manufacturer and distributor in China. We mainly produce galvanized steel, galvalume steel, prepainted galvanized steel, etc. Moreover, our factory is located in Boxing County, Shandong Province. You are welcome to visit our factory and galvanized steel production lines. Usually, Galvanized steel coil uses hot rolled or cold rolled steel as raw materials, and through a hot dip galvanizing process to manufacture. Compared with other steel materials, galvanized steel coil is less expensive, has the benefits of long service life, prevents steel from corrosion, has a wide range of applications, provides comprehensive protection, etc.  For further details, please keep reading.

Uses

Galvanized steel coil mainly offers anti-corrosion protection for steel. Coating a zinc layer on the steel surface can isolate the touch between steel and the external environment, reduce the occurrence rate of corrosion, and lengthen the service life of steel. Therefore, GI coils are applicable in construction areas, home appliances industries, transportation areas, automobile industry, and so on. There are some application details for your reference.

• In the construction area: Because of its corrosion resistance and anti-fire properties, you can use galvanized coils to produce roofing sheets, shingles, and security windows.
• In the home appliance industry, Galvanized steel coils have been widely applied. Usually, we use it to manufacture the shell and internal parts of refrigerators, washing machines, microwave ovens, printers, and other household appliances.
• In the automobile area: Our coils can be used to process automobile bodies, doors, roofs, and other parts, as well as automobile shells, exhaust pipes, oil tanks, etc
• In the transportation area: owing to its high strength and excellent corrosion resistance, the galvanised steel coil is often used to make Bridges, highway guardrails, road light poles, and other traffic facilities.

In addition, with the development of industry and construction, galvanized coils are increasingly widely used because of their excellent performance. The demand for galvanized coil has been increased.  Specifically, in the construction of highways, urban rail transit construction, oil and gas pipelines, and other significant infrastructure projects.

Types

According to different production processes, GI steel coil can be divided into hot-dip galvanized steel coil and electro-galvanized steel coil.

Hot dip galvanized steel coil

Hot dip galvanized steel coil is widely used in manufacturing, construction, automobile, and other areas, that is because hot dip galvanized steel coil has a smooth surface, good processing performance, and can prevent corrosion. Furthermore, our GI steel coil is dipping steel into a molten zinc solution for galvanizing. Customers benefit from cheaper manufacturing costs.

Electro-galvanized steel coil

Instead, electro-galvanized steel coils are coating a layer of zinc on the steel surface. It is excellent decorative and corrosion-resistant and is mainly used in IT, construction, home appliances, and other industries.

In general, hot dip galvanized steel coil and electro-galvanized steel coil are all our hot-selling products. In some aspects, they have some differences. About zinc thickness, hot dip galvanized steel coil is more thicker. Therefore it is suitable for outside environments. Regarding corrosion resistance, electro galvanized has lower corrosion resistance than hot dip galvanizing.

Moreover, the electro-galvanized production cost is higher. Considering the above factors, you can select a suitable steel coil when you purchase. For further questions, please don’t hesitate to contact us!

Galvanized Steel Coil Price

Various factors affect the galvanized steel coil price, such as specification, surface structure, tunnage, etc. Regarding surface structure, we have regular spangles, small spangles, big spangles, and zero spangles, and you can elect it based on your requirements. In different regions and manufacturers, the price is also not the same. To save your costs, we recommend you acquire several factories’ prices and choose the cost-effective supplier. In summary, the price of galvanized coils is influenced by several elements, and the specific price needs to be determined according to specifications, brands, transportation locations, and market demand. If you want to know the latest price about steel materials, welcome feel free to contact us.
