Hot Dip Galvanizing And Electroplating Plant

We are Making, Exporting and Supplying Hot Dip Galvanizing And Electroplating Plants in Shijiazhuang, Hebei, China. Many friends want to know, galvanization processing includes hot galvanization and electrogalvanization, which is better? What's the difference? In response to this question, galvanzing plant manufacturer, Anno, will give you a simple answer.
The zinc coating of electrogalvanizing is more pure, while the impurity of zinc coating is more, which makes the zinc coating of hot galvanizing process easy to produce microbattery action, and this kind of situation is not easy to appear in electrogalvanizing process. In this case, the corrosion of electrogalvanizing is better than that of hot galvanizing.
Hot dip galvanizing and electroplating, which is more corrosion resistant?
However, the zinc coating in hot galvanizing process consists of pure zinc layer and ferrozinc alloy layer. The electroplating process only has pure zinc layer. Because there are more ferrozn alloy layers, the thickness of zn layer in hot-dip galvanizing process is much thicker than that in electrogalvanizing process. This makes the corrosion resistance of hot-dip galvanizing better than that of electroplating.
