Channel steel is easy to rust in air and water. According to relevant statistics, the annual loss caused by corrosion accounts for about one tenth of the entire steel production. In order to make the channel steel has a certain corrosion resistance, and at the same time give the decorative appearance of the product, so it is generally used in the way of galvanized surface treatment.(galvanized channel steel )
Galvanizing is a surface treatment method with high performance and price ratio. Because zinc is not easy to change in the dry air, and in the humid air, the surface can generate a very dense galvanized film, after galvanized treatment of channel steel surface will be very beautiful, but also has strong corrosion resistance.
In the liquid state of zinc, after quite complex physical and chemical processes, not only a thicker zinc layer is plated on the channel steel firmware, but also a zinc-iron alloy layer is formed. This plating method not only has the corrosion resistance characteristics of electric galvanizing, but also has the incomparable strong corrosion resistance of electric galvanizing because of the zinc and iron alloy layer. Therefore, this plating method is especially suitable for a variety of strong acid, alkali fog and other strong corrosion environment.
There are many channel steel manufacturers, it is recommended that you must polish your eyes when buying, do not blindly pursue low prices, choose a reliable manufacturer is much more important than the price!
