Galvanized sheet is made of steel plate with a layer of zinc on the surface. It is an economical and effective rust prevention method often used. About half of the world’s zinc production is used in this process. It can play the role of anti-corrosion to a certain extent.
Galvanized steel sheet is also called hot-dip galvanized steel sheet. The steel sheet is immersed in the dissolved zinc bath to make its surface adhere to a layer of zinc. At present, it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate.
Hot dip galvanized non alloy steel plate can be used for general purpose or deep drawing and biting. The higher the zinc content of the coating, the stronger the corrosion resistance, and the less the zinc content, the better the mechanical properties.
Hot dip galvanized alloy strip can be used for structure, stamping and cold forming. This material has good weldability and adhesion, but it is easy to peel during treatment.
Electro galvanized steel plate: the steel plate is galvanized by energizing, but the zinc plated in this way is relatively thin and the corrosion resistance is relatively poor.
Expansion: stainless steel uses trace elements to change the composition of steel, so as to achieve anti-corrosion effect. Electro galvanized sheet is plated on conventional steel plate at the expense of zinc. 200 degrees and 300 degrees have no effect on the metal, but there will be slight changes according to the surrounding environment, but it will take a long time.
