Galvanized Steel Coil Corrosion Resistance

Aug 07, 2017

Galvanized steel coil is the thin steel plate immersed in the melting of the zinc tank, so that the surface adhesion of a layer of zinc steel plate. Galvanized steel coils can be divided into hot-rolled galvanized coil and cold-rolled galvanized coil, they are mainly used for construction, home appliances, automobiles, containers, transportation and home industry and other fields. Galvanized Steel Coil Especially in steel construction, automobile manufacturing, steel warehouse manufacturing and other industries.

Galvanized steel coil is characterized by: strong corrosion resistance, good surface quality, Galvanized Steel Coil benefit from deep processing, economical and practical. Product standards: the implementation of corporate standards / GB.

Galvanized Steel Coil Classification and use

According to the production and processing methods can be divided into the following categories:

① hot-dip galvanized steel plate. The steel sheet was immersed in a molten zinc bath so that a thin layer of zinc was adhered to the surface thereof. At present, the main use of continuous galvanizing production process, that is, into a roll of steel plate is continuously immersed in the melting of zinc plating made of galvanized steel;

② galvanized steel plate. The steel plate is also made by hot-dip method, Galvanized Steel Coil but immediately after the tank, it is heated to about 500 ° C to produce zinc and iron alloy film. This galvanized sheet has a good coating of the adhesion and weldability;

③ galvanized steel plate. The galvanized steel sheet produced by electroplating has good processability. But the coating is thinner, corrosion resistance is not as hot dip galvanized sheet;

④ single-sided plating and double-sided galvanized steel plate. Single-sided galvanized steel, that is, only one side of the galvanized products. In the welding, painting, Galvanized Steel Coil anti-rust treatment, processing, etc., than double-sided galvanized sheet better adaptability. In order to overcome the shortcomings of single-sided non-coated zinc, there is a coated with a thin layer of zinc on the other side of the galvanized sheet,

⑤ alloy, composite galvanized steel. It is made of zinc and other metals such as lead, zinc alloy and even composite plated steel plate. This steel plate has both excellent rust resistance and good coating performance.

In addition to the above five, there are color galvanized steel, printing coated galvanized steel, PVC laminated galvanized steel and so on. But the most commonly used is still hot-dip galvanized sheet.

Galvanized steel plate can be divided into general use, roof, Galvanized Steel Coil building with the outer side of the board, structural use, ridge board with, with the deep drawing and other galvanized steel.
