Hot-dip galvanized channel steel is a kind of profile, and its sales volume is also very considerable. The hot-dip galvanized channel steel is a long strip of steel with a groove shape, so how is it produced? Next, Yan Xinsen domainYanXin Metal will take you to understand.
The hot-dip galvanizing channel process includes: raw material inspection - pickling - cleaning - zinc assisting - drying - galvanizing - cooling - passivation - cleaning - inspection of finished products - inspection and packaging. The main method of galvanizing the surface of hot-dip galvanized steel is hot-dip galvanizing.
Hot-dip galvanizing is developed from the older hot-dip method. With the rapid development of cold-rolled strip, the hot-dip galvanizing industry has developed on a large scale. Hot dip galvanizing is a very excellent one in various coating methods for protecting steel substrates. It is a state in which zinc is in a liquid state. After a relatively complicated physical and chemical action, not only a thick layer of pure zinc is blocked on the steel, but also a zinc-iron alloy layer is formed. The corrosion resistance of electrogalvanized steel is due to the fact that it has a zinc-iron alloy layer. It also has strong corrosion resistance that cannot be compared with electrogalvanized. Therefore, this plating method is particularly suitable for use in various strong corrosive environments such as strong acid and alkali mist, so that hot-dip galvanizing channel steel quickly occupied the market.
