PRODUCT DESCRIPTION HDGI is hot-dip galvanized steel sheet, which is coated with a layer of zinc on the surface of steel. In fact, the steel plate is easy to be oxidized by water and other oxides in the air, thus being corroded. Zinc is actually intended to better protect steel plates. Galvanized steel sheet has two main advantages, one is adhesion, the other is weldability. Because of these two advantages, it is widely used in construction, industry, automobile industry and commerce. Another important feature is corrosion resistance, which has a good impact on the manufacturing of household appliance shells. According to production and processing methods, it can be divided into the following categories: Hot dip galvanized steel sheet. The thin steel plate is immersed in the molten zinc bath to make its surface adhere to the zinc layer. At present, it is mainly produced by continuous galvanizing process, that is, rolling steel plate and molten zinc are continuously immers…
