Everything About Galvanized Steel Coil
Regarding galvanized steel coils, we need to know that its steel is a carbon flat steel product with a galvanized layer on the surface. This coating increases the corrosion resistance of steel coils or plates.
 
Dip galvanized steel sheets and coils are carbon steel made using a hot-dip galvanizing process. The end result of this process is a layer of zinc on each side of the steel plate or coil that adheres tightly to the steel by forming an iron-zinc alloy bonding layer.

This bonding layer is formed through a diffusion process when heated steel comes into contact with molten zinc. GNEE can provide hot-dip galvanized steel sheet and coil to meet your ASTM requirements with customer-driven surface finish options.

The most common method for galvanizing steel coils is the hot dip galvanizing process.

Galvanized steel coils are mainly produced by the continuous galvanizing process, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel coils. This kind of steel coil is made by hot-dip method. After coming out of the tank, it is heated to about 500℃ immediately to form an alloy film of zinc and iron, which has good paint adhesion and weldability.

During the hot-dip galvanizing process, coils of carbon steel are immersed in an acid bath to remove the scale. Once the steel has been cleaned and descaled, it is continuously immersed in a bath of molten zinc to create a metallurgical bond and a protective coating with controlled coating weight. The weight of the coating increases the corrosion resistance of the steel.

The zinc liquid in the hot-dip galvanizing process contains trace elements such as aluminum. The presence of these traces optimizes coating adhesion and increases the ductility of galvanized steel, galvanized steel coils and galvanized steel cut coils, allowing the material to be formed into hundreds of products we use every day.

How to seal-pack galvanized steel coils?

The zinc steel coil should first be wrapped with anti-rust paper and plastic film, install inner and outer peripheral buffer corner protectors, and then install the inner peripheral protective plate (the standard is a direct layer of inner peripheral protective plate, but it is best to add one inside Layer inner peripheral buffer guard plate), then install the outer peripheral buffer material guard plate, then install the outer peripheral guard plate (metal) and the end round guard plate, then install the inner and outer peripheral metal corner protectors, and finally tie them firmly with straps, circumferentially and There are no less than three radial roots.
