Galvanized sheet refers to a thick steel plate coated with a layer of zinc on the surface. Hot dip galvanizing is a frequently used economic development and reasonable anti-rust treatment method, about half of the world's zinc production is used for such processing technology. So what is the classification of galvanized sheet, galvanized steel sheet manufacturer tells you.

According to the manufacturing, production and processing methods, it can be divided into the following types:

① Hot dip galvanized China color corrugated steel sheet manufacturers. Infiltrate the cold-rolled steel sheet into the molten zinc bath

A cold-rolled steel sheet with a layer of zinc adhered to its surface. At this stage, the key is to use continuous hot-dip galvanizing process technology, that is, the thick steel plate is continuously immersed in the molten zinc plating bath to make a galvanized steel plate;

② Fine grain strengthened galvanized steel sheet. These thick steel plates are all manufactured by hot dip method, but they are heated to 500 ℃ immediately after being out of the tank to convert them into aluminum alloy plastic films of zinc and iron. This type of galvanized sheet has excellent adhesion of architectural coatings and weldability;

③ Electro-galvanized steel sheet. The production of this kind of galvanized steel plate by electroplating has excellent process performance. But the coating is thinner and the corrosion resistance is not as good as hot dip galvanized sheet;

④Single-sided plating and two-sided difference galvanized high quality Galvalumed steel sheet. Single and double-sided galvanized steel sheet, that is, hot galvanized products on only one side. In welding, spraying, rust prevention, production and processing, it has stronger adaptability than galvanized sheets on both sides.

In order to get rid of the defects of single and double-sided uncoated zinc, there is another kind of galvanized sheet coated with chromatographic zinc on the other side, that is, the difference between the two sides of the galvanized sheet;

⑤ Aluminum alloy, composite galvanized steel plate. This is a thick steel plate made of zinc and other metal materials such as aluminum, lead, zinc, etc. made of aluminum alloy or even composite type. This kind of thick steel plate not only has extraordinary anti-rust treatment characteristics, but also has excellent spraying characteristics;

In addition to the above-mentioned five types, there are also colorful galvanized Galvanized Corrugated Steel Sheet price, clothing printing spray-coated galvanized steel sheets, polyethylene laminated galvanized steel sheets, etc. But the most common at this stage is still hot dip galvanized sheet. Key manufacturers and import manufacturing countries:

① China's key manufacturers: Wuhan Iron and Steel, Shougang, Anshan Iron and Steel Huangshi City, China Metallurgical Hengtong, Shougang, Pangang, Handan Iron and Steel, Maanshan Iron and Steel, Kaijing of Fujian Province, etc .;

② Overseas key manufacturing state-owned countries such as Japan, France, Ukraine, Netherlands, Japan, etc.
