Information Summary:
① Alloyed galvanized steel sheet. This type of steel sheet is also manufactured by hot-dipping, but immediately after it comes out of the tank, it is heated to about 500°C to produce an alloy film of zinc and iron. This type of galvanized steel sheet has good paint adhesion and weldability.
② Hot-dipped galvanized steel sheet. A thin steel sheet that is dipped into a molten zinc bath so that a layer of zinc adheres to its surface. At present, the main use of continuous galvanizing process production, that is, the coil of steel plate continuously immersed in molten zinc bath made of galvanized steel; ④ single-sided plating and double-sided plating.
④ single-sided plating and double-sided differential galvanized steel. Single-sided galvanized steel, that is, only on one side of the galvanized product. It has better adaptability than double-sided galvanized steel sheet in terms of welding, painting, anti-rust treatment and processing.
(iii) Electro-galvanized steel sheet. Manufacturing this galvanized steel sheet by electroplating method has good processability. However, the coating is thin, and the corrosion resistance is not as good as hot-dip galvanized sheet.
In order to overcome the shortcomings of single-sided uncoated zinc, there is a galvanized sheet coated with a thin layer of zinc on the other side of the galvanized sheet, i.e., double-sided differential galvanized sheet; ⑤ alloy, composite galvanized steel.
⑤ Alloy and composite galvanized steel sheet. It is made of zinc and other metals such as aluminum, lead, zinc and other alloys and even composite galvanized steel. This kind of steel plate has both excellent rustproof performance and good painting performance;.
In addition to the above five, there are also colored galvanized steel, printed and painted galvanized steel, PVC laminated galvanized steel, etc.. However, the most commonly used is still hot dip galvanized steel.
