PRODUCT DESCRIPTION
Galvanized Steel coils have different surface conditions due to different treatment methods in the coating process, such as ordinary zinc coils, fine zinc coils, flat zinc coils, zinc-free coils, and phosphating-treated surfaces. Galvanized coils should have a good appearance and must not have defects harmful to the use of the product, such as no plating, holes, cracks and scum, excessive plating thickness, scratches, chromic acid dirt, white rust, etc.
According to the production and processing methods, it can be divided into the following categories:
a) Hot-dip Galvanized Steel Coil. The thin Steel Coil is dipped into the molten zinc bath to make the thin steel coil with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the coiled Steel Plates are continuously dipped in a galvanizing bath with molten zinc to make galvanized Steel Coils.
b) Alloyed galvanized steel coil. This kind of steel coil is also made by hot dip method, but it is heated to about 500℃ 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;
c) Electrogalvanized steel coil. The galvanized steel coil manufactured by electroplating has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized coils.
d) Single-sided and double-sided galvanized steel coils. Single-sided galvanized steel coil, that is, a product that is galvanized on only one side. It has better adaptability than double-sided galvanized coils in terms of welding, painting, anti-rust treatment, and adding. In order to overcome the shortcomings of one side without galvanizing, there is another kind of galvanized coating with a thin layer of zinc on the other side.
Coil, that is, double-sided differential galvanized coil.
e) Alloy, composite galvanized steel coil. It is a steel coil made of zinc and other metals such as lead and zinc alloy or even composite plated. This kind of steel coil not only has excellent antirust performance, but also has good coating performance.
In addition to the above five types, there are also colored galvanized steel coils, printed and coated galvanized steel coils, polyvinyl chloride laminated galvanized steel coils, etc. But the most commonly used one is still hot-dip galvanized coil.
According to the application, galvanized steel coil can be divided into general use, roof use, building outer panel use, structure use, tile ridge board use, stretching use and deep drawing use.
The reason why the surface of the galvanized coil is coated with a layer of zinc on the surface of the steel is actually because the Steel Plate is easily oxidized by water and other oxides in the air, thereby being corroded. The coating with a layer of zinc is actually to better protect the steel. Galvanized coils have two major advantages, one is adhesion and the other is weldability.
It is precisely because of these two advantages that it is widely used in construction, industry, automotive industry and commerce. Another important feature is corrosion resistance, which can have a good effect on the manufacture of home appliance shells.
