A thick steel plate coated with zinc

November 8, 2022

What is the classification of galvanized steel plate discussed

 

Galvanized sheet is a thick steel plate coated with zinc. Hot dip galvanizing is an economical and reasonable antirust treatment method, and about half of the world's zinc production is used for this kind of processing technology. So what are the galvanized plates classified, galvanized steel plate manufacturers say to you.

 

According to the manufacturing and production processing mode can be divided into the following types:

 

① Hot dip galvanized steel plate. Penetrate the cold rolled steel plate into the melted zinc groove

 

A cold rolled steel plate that is coated with zinc. At the present stage, the key selection of continuous hot dip galvanizing process manufacturing, that is, the plate of thick steel plate continuously immersed in the melting of zinc plating groove to make galvanized steel plate;

 

② Fine crystal reinforced galvanized steel plate. This kind of thick steel plate is made by hot dip, but immediately after the tank, it is heated to about 500℃, so that it is converted into zinc and iron aluminum alloy plastic film. This kind of galvanized sheet has excellent architectural coating tightness and welding properties;

 

③ Electric galvanized steel plate. The production of galvanized steel plate by electroplating has excellent technical properties. But the coating is thin and the corrosion resistance is not as good as that of hot-dip galvanized sheet.

 

④ Single and double plated and double difference galvanized steel plate. Single and double galvanized steel, that is, hot galvanized goods only on one side. In electric welding, spraying, rust prevention, production and processing and other aspects, it has stronger adaptability than two-sided galvanized sheet.

 

In order to get rid of the defect of single and double sides without zinc coating, there is a galvanized sheet coated with zinc chromatography on the other side, that is, two-sided differential galvanized sheet;

 

Aluminum alloy, composite galvanized steel plate. This is a thick steel plate made of zinc and other metal materials such as aluminum, lead, zinc, and even composite plating. This kind of thick steel plate not only has extraordinary anti-rust treatment characteristics, but also has excellent spraying characteristics;

 

In addition to the five kinds, there are also colorful galvanized steel plate, clothing printing spraying galvanized steel plate, polyethylene laminated galvanized steel plate and so on. But at present the most common is still hot dip galvanized sheet. Key manufacturers and importing countries:

 

① Key manufacturers in China: WISCO, Shougang, Angang Huangshi, MCC Hengtong, Shougang, Panzhihua Steel, Handang, Masteel, Fujian Kaijing, etc.;

 

(2) Overseas key manufacturing state-owned Japan, France, Ukraine, the Netherlands, Japan, etc.
