Product Description
Galvanized Steel Coil is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot dip galvanized coil supplied in coil form after coiling. Therefore, Galvanized Steel Sheet (coil) can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil. They are mainly used in the fields of construction, household appliances, automobiles, containers, transportation and household industry. Especially in steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economy and practicality, etc.
Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized steel coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized steel coil is an essential fabrication component.
The requirements of chemical composition of galvanized coil are different in different countries. The national standard is to detect the content of carbon, manganese, phosphorus, sulfur and silicon.
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.

Galvanized Steel Coil Types
According to the processing method, we divide galvanized steel into the following categories:
1. Hot-Dip Galvanized Steel Coil
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Steel Coil
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
