The Difference between Electric Galvanizing And Hot Galvanizing

Hot dip galvanizing, also known as hot dip zinc and hot dip galvanizing, is an effective way of metal anticorrosion, mainly used in various industries of metal structure facilities.  It is to immerse the steel parts after rust removal into zinc solution melted at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anticorrosion.  

Electrogalvanizing, also known as cold galvanizing in the industry, is the process of using electrolysis to form uniform, dense and well-combined metal or alloy deposition layer on the surface of the workpiece.  Compared with other metals, zinc is relatively cheap and easy to coat a metal, a low value corrosion resistance electroplating, is widely used to protect steel parts, especially against atmospheric corrosion, and used for decoration.
