Hot-dip galvanized channel steel can be divided into hot-dip galvanized channel steel and hot-blown galvanized channel steel according to different galvanizing processes. The rust-removed steel parts are immersed in molten zinc liquid at about 440~460°C to make the steel A zinc layer is attached to the surface of the component to prevent corrosion.
The main method used for surface galvanizing of channel steel is hot dip galvanizing. Hot-dip galvanizing was developed from the older hot-dip method. It has a history of 170 years since France applied hot-dip galvanizing to industry in 1836. However, in the past 30 years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has developed on a large scale.
Galvanized channel steel is a common metal material widely used in construction, bridges, vehicles and other fields. Its excellent mechanical properties and corrosion resistance make it a very popular steel.
