Galvanized plate refers to a steel plate plated with a layer of zinc. Galvanizing is an economical and useful anti -corrosion method adopted. About half of the global zinc production are used for this process. Galvanized steel plate is a method of preventing steel plates from overview of steel plates and delaying its service life. It is used as a layer of metal zinc on the steel plate. This type of thin steel plate is called galvanized plate. 

What are the galvanized plates and the fields of use and processing methods can be divided into the following categories: 

① Hot immersion galvanized plate. Immersed the thin steel plate into the dissolved zinc groove to make it overview a thin steel plate that adheres to a layer of zinc. At present, the important adoption of continuous galvanized processes is produced, that is, the steel plates that are rolled into a rolled roll are continuously immersed in a zinc grooved galvanized steel plate; 

② Alloy galvanized steel plate. This kind of steel plate is also made of heat immersion method, but after the groove is out, it immediately heated it to about 500 ° C, making it the film of zinc and iron alloy. This type of galvanized plate has the closeness and welding of the exquisite coatings; 

③ Electro -galvanized steel plate. Make such galvanized steel plates with electroplating method. However, the plating is thinner, and the corrosion resistance is not as good as the heat -soaking method. 

④ A single -sided galvanized steel plate, which is only galvanized. In terms of welding, coating, rust -proofing, processing, etc., it has better conformity than double -sided galvanized plates. In order to surrender the errors of single -sided unspolling zinc, there is another kind of galvanized plate with thin layer of zinc, that is, double -sided galvanized plates; 

⑤ Alloy and composite galvanized steel plate. It is a steel plate made of zinc and other metals such as lead, zinc, and even compound plated.
