How the hot-dip galvanizing channel is produced ?

Hot-dip galvanized channel steel is a kind of profile, andits sales volume is also very considerable. The hot-dip galvanized channelsteel is a long strip of steel with a groove shape, so how is it produced?

The hot-dip galvanizing channel process includes: rawmaterial inspection—pickling—cleaning —zinc assisting—drying—galvanizing—cooling—passivation—cleaning—inspection of finished products—inspection and packaging. The main method ofgalvanizing the surface of hot-dip galvanized steel is hot-dip galvanizing.

Hot-dip galvanizing is developed from the older hot-dipmethod. With the rapid development of cold rolled strip, the hot-dipgalvanizing industry has developed on a large scale. Hot dip galvanizing is avery excellent one in various coating methods for protecting steel substrates.It is a state in which zinc is in a liquid state. After a relativelycomplicated physical and chemical action, not only a thick layer of pure zincis blocked on the steel, but also a zinc-iron alloy layer is formed.
