Galvanized steel channel hot rolled manufacture
Galvanized steel channel is a long steel with a groove-shaped section. Hot-dip galvanized channel steel can be divided into hot-dip galvanized channel steel and hot-blown galvanized channel steel according to the different galvanizing process. It is the steel after derusting. The parts are immersed in the molten zinc at around 440~460℃ to make the surface of the steel parts adhere to the zinc layer, thereby achieving the purpose of anti-corrosion. Among various coating methods for protecting steel substrates, hot-dip galvanizing is a very good one. It is when the zinc is in a liquid state, and after quite complex physical and chemical actions, the steel is not only plated with a thicker pure zinc layer, but also a zinc-iron alloy layer is formed. This plating method not only has the corrosion resistance characteristics of electro-galvanization, but also has a zinc-iron alloy layer. It also has strong corrosion resistance unmatched by electro-galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali mist and other strong corrosive environments.
