The main method for galvanizing the surface of the channel steel is hot-dip galvanizing. The galvanized channel steel is an effective metal anti-corrosion method and is mainly used in metal structure facilities of various industries. In fact, the rust-removed steel part is immersed in the zinc liquid that is melted at a temperature of about 440 to 460° C. so that a zinc layer is attached to the surface of the steel member, so that the purpose of corrosion protection is achieved. For those who have this need, it is very necessary to have a theoretical weight scale for galvanized channel steel . Here I briefly introduce the relevant knowledge of galvanized channel steel for everyone, understand the theoretical weight of galvanized channel steel and galvanized channel steel.
Galvanized channel steel introduction
Hot-dip galvanized channel steel can be divided into hot-dip galvanized channel steel and hot-blow galvanized channel steel according to different galvanizing processes. The rust-removed steel pieces are immersed in zinc liquid that is melted at about 440-460°C to make steel. A zinc layer adheres to the surface of the component, which serves the purpose of corrosion protection.
The main method of galvanizing the surface of the channel steel is hot-dip galvanizing. Hot-dip galvanizing was developed from the older hot-dip coating method. Since France applied hot-dip galvanizing to the industry in 1836, it has been 170 years old. However, in the past 30 years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has achieved large-scale development.
Hot dip galvanizing is a very good one in various coating methods for protecting steel substrates. It is in the liquid state of zinc, after a rather complex physical and chemical effects, not only the thick pure zinc layer on the steel, but also a zinc-iron alloy layer. This plating method not only has the corrosion resistance characteristics of electrogalvanizing, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that electro-galvanizing cannot match. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali mist and other strong corrosion environment.
Galvanized channel principle
Hot dip galvanized layer is formed in three steps at high temperature liquid state:
1. The surface of the iron base is dissolved by the zinc liquid to form a zinc-iron alloy phase layer;
2. The zinc ions in the alloy layer are further diffused into the matrix to form a zinc-iron mutual soluble layer;
3. The surface of the alloy layer is surrounded by a zinc layer.
Galvanized channel steel features
(1) A thick, dense layer of pure zinc covers the surface of the steel, which prevents contact between the steel substrate and any corrosion solution and protects the steel substrate from corrosion. In the general atmosphere, the surface of the zinc layer forms a very thin and dense zinc oxide layer surface, which is hardly soluble in water and therefore plays a protective role for the steel substrate. If zinc oxide and other components of the atmosphere form insoluble zinc salts, the corrosion protection is more ideal.
(2) It has an iron-zinc alloy layer, which is densely bonded and exhibits unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;
(3) Due to strong bonding, zinc-iron mutual solubility, with strong wear resistance;
(4) Since zinc has good ductility, the alloy layer adheres firmly to the steel base, so the hot-dip coating can be subjected to cold punching, rolling, wire drawing, bending, and other molding without damaging the plating layer;
(5) After the hot-dip galvanizing of the steel structure, it is equivalent to an annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during steel welding, and facilitate the turning of the steel structure.
(6) The surface of the hot-dip galvanized part is bright and beautiful.
(7) The pure zinc layer is the most plastic layer of galvanized layer in hot-dip galvanizing. Its nature is close to that of pure zinc and it is ductile, so it is rich in flexibility.

Galvanized channel steel process
Hot dip galvanized channel steel process: raw material inspection → pickling → cleaning → zinc-assisted → drying → galvanizing → cooling → passivation → cleaning → finished product inspection → inspection packaging.
Galvanized channel steel prices
Galvanized channel steel price is about 3,500 yuan a ton. The main method of galvanizing the surface of the channel steel is hot-dip galvanizing. Hot-dip galvanizing was developed from the older hot-dip coating method. Since France applied hot-dip galvanizing to the industry in 1836, it has been 170 years old.
