The following small series of Shandong channel steel manufacturers for you to introduce. Channel steel is very simple to rust in air and water. According to the calculation of relevant parts, the loss caused by corrosion accounts for about one tenth of the total steel output value every year.
In order to make the channel steel have a certain corrosion resistance and give the decorative appearance of the products together, the galvanized method is generally used for the surface treatment of the channel steel. Among the various surface treatment processes of the channel steel, galvanizing is a widely used external surface treatment method with very high performance price ratio. Because zinc is not easy to change in dry air, but in humid air.
Channel steel manufacturers can produce a very fine galvanized film on the surface. After galvanizing, the appearance of channel steel will be very beautiful, and it has strong corrosion resistance. The common surface treatment process of channel steel is not only plated with thicker zinc layer, but also generates a kind of zinc after appropriate disordered physical and chemical effects in the liquid state of zinc- Ferroalloy layer.
This plating method not only has the corrosion resistance characteristics of zinc plating, but also has the strong corrosion resistance which cannot be compared with zinc iron alloy layer. Therefore, this plating method is especially suitable for various strong acid, alkali fog and other strong corrosion environment. In general atmosphere, the surface of zinc layer forms a very thin and dense zinc oxide layer, which is difficult to dissolve in water Steel plays a certain role in maintenance.
The above is about the appearance of channel steel treatment process, hope to help you, if you have other questions, welcome to consult Shandong channel steel manufacturers http://www.jnlhjscl.com Website
