Galvanized channel steel is an effective metal corrosion protection method and is mainly used in metal structure facilities in various industries.
Hot-dip galvanizing channel steel can be divided into hot-dip galvanizing channel steel and hot-dip galvanizing channel steel according to different galvanizing processes. The rust-removed steel piece is immersed in zinc liquid melted at about 440~460 °C to make steel. The surface of the component is attached with a zinc layer to protect the surface.
The main method used for galvanizing the surface of channel steel is hot-dip galvanizing. Hot-dip galvanizing has evolved from older hot-dip methods, and since France applied hot-dip galvanizing to industry in 1836, it has been 170 years old. However, in the past 30 years, with the rapid development of cold rolled strip, the hot dip galvanizing industry has achieved large-scale development.
Hot-dip galvanizing channel steel process: raw material inspection → pickling → cleaning → zinc assist → drying → galvanizing → cooling → passivation → cleaning → finished product inspection → inspection packaging.
