What's difference between Hot dip galvanizing and Cold galvanizing ?

Hot dip galvanized is the ingot melted high temperatures,a number of supplementary material in place,then dipped galvanized metal structure slot,the metal component on a layer of zinc coating.The advantages of hot dip galvanizing corrosion of his ability,adhesion and hardness of zinc coating is better.


Cold galvanized is the zinc salt solution by electrolysis.to the plating on the coating,generally do not have heating,small amount of zinc,the wet environment is very easy to fall off.

Hot dip galvanizing isn't cold galvanized delicate bright appearance,but the thickness of zinc coating of cold galvanizing aspects of hot dip galvanizing is a few times,galvanized corrosion resistance is also several times.
