When zinc is used in a simple electroplating method without further processing, it changes color over time in the presence of air and becomes dark gray. To avoid this problem, a kind of shiny zinc with a white chromate or lacquer finish is used and this is used when the final product has a decorative application. Our collection is one of the Top notch galvanized sheet Distribution centers and distributes this product all over the country and has attracted many buyers.
What is the cost of galvanized sheet?
Although this decorative insert is less durable than nickel-chrome, it provides better protection of thin nickel-chrome coatings against corrosion, with the difference that it is much cheaper in many cases. Galvanized sheet coating methods: Passing the part to be coated through a bath of molten zinc metal called hot dip galvanizing technique.
The use of coating methods called cold galvanizing or electro galvanizing. In hot-dip galvanized sheet metal, the connection between the part and the metal must be a solid and durable connection, that is, an intermetallic compound is formed between the part and the coating metal. The durability of this coating depends on the type of method and the degree of accuracy in doing so and the quality of the coating. Hot dip galvanizing is a method of protection made by placing the part in a molten bath. Currently, different types of sheet metal can be hot dip galvanized.
This process, despite its simple explanation, is a complex and difficult process. Due to the immersion of the sheet in the molten zinc bath, a series of chemical reactions take place and finally this process ends after the alloying process. In hot dip galvanizing, different variables depend on how the process is carried out, the formation of alloy layers, the thickness of each layer, etc. Effects. These factors include the chemical composition of the base metal, the composition of the melt bath, the quality of the zinc ingots used, the bath temperature, the dipping time, the dipping speed, the flux used, etc.
In order to perform hot galvanizing process, the surface of the sheets must be thoroughly prepared. For this purpose, first the surface of the sheet is degreased, then it is acid-washed and then washed again, and finally the part is immersed in a suitable flux and the part is preheated.
