Processing method of galvanized steel plate

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

① Hot dip galvanized steel plate. The sheet steel is dipped into the melted zinc tank so that the surface is adhered to a layer of zinc sheet steel. Now the first choice of continuous galvanizing process production, that is, the steel plate into a roll of continuous immersion in the melting of zinc plating tank made of galvanized steel plate;

② alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to produce a zinc and iron alloy film. This galvanized sheet has excellent coating tightness and weldability;

③ Electric galvanized steel plate. The galvanized steel plate made by electroplating has excellent workability. But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet;

④ Single-side plating and double-side difference galvanized steel plate. Single-sided galvanized steel plate, that is, galvanized products only on one side. It has better adaptability than double-sided galvanized sheet in welding, coating, rust prevention and processing. In order to overcome the defect of uncoated zinc on one side, there is a galvanized sheet coated with a thin layer of zinc on the other side, namely double-sided differential galvanized sheet;

⑤ Alloy, composite galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc alloy and composite plating of steel plate. This steel plate not only has excellent rust prevention function, but also has excellent coating function;
