Product Description

Product Description

 

What is Galvanized Steel CoilGalvanized coil, a thin steel sheet that is dipped in a bath of molten zinc to adhere a layer of zinc to its surface. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously dipped in a plating tank with molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500ºC immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Zinc Coating
Usually Zinc Coated can be Z30 - Z275G , The weight of the zinc layer should be provided according to customer requirements
 

Galvanized Steel Coil Production Process

Hot-rolled coils become cold-rolled coils after pickling, phosphating, annealing and other processes,Immerse the steel coil in the molten zinc tank to make the surface adhere to the zinc coated.

Type Of Spangle

Usually there are four types of Spangle .
1) Regular and Big spangle During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with obvious spangle morphology.

2)Small Spangle During the solidification process of the zinc layer, the zinc grains are artificially restricted to form a spangle coating as small as possible.

3)Zero Spangle

By adjusting the chemical composition of the plating solution, there is no visible spangle morphology and a uniform coating on the surface.

Galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils, which are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.

About quality Control
Usually, after all the products finished production, the factory laboratory will take a certain proportion of the products according to the proportion, and carry out the inspection of zinc layer, thickness, width, etc., and also accept any third-party inspection arranged by the customer , such as QC inspection, SGS inspection and so on.
