Galvanized channel steel, also called hot-dip galvanized channel steel and hot-dip galvanized channel steel, is an effective method of metal anti-corrosion and is mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts into molten zinc liquid at about ~ ℃, so that the zinc layer is attached to the surface of the steel components, thereby achieving the purpose of anti-corrosion. Nowadays, the main method used for galvanizing the surface of channel steel is hot dip galvanizing. Hot-dip galvanizing is developed from the older hot-dip method. It has a history of 20 years since France used hot-dip galvanizing in industry. However, in recent years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has developed on a large scale. Among various coating methods for protecting steel substrates, hot dip galvanizing is an excellent one. It is when zinc is in a liquid state, and after a very complex physical and chemical reaction, the steel is not only plated with a thicker layer of pure zinc, but also a zinc-iron alloy layer is formed. This plating method not only has the corrosion resistance characteristics of electroplated zinc, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that cannot be compared with electroplated zinc. Therefore, this plating method is particularly suitable for strong corrosive environments such as various strong acid and alkali mist.
Principle of hot-dip galvanizing
The hot-dip galvanizing layer is formed by zinc in a high-temperature liquid state in three steps. The iron-based surface is dissolved by the zinc liquid to form a zinc-iron alloy phase layer. The zinc ions in the alloy layer further move toward the matrix. Diffusion forms a zinc-iron mutual miscibility layer and the surface of the alloy layer is surrounded by a zinc layer.
