Hot Dipped Galvanized and Cold Galvanized

     Hot dip galvanized, also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion. It is the rust removal of steel immersed in about 500 ℃ melting molten zinc, zinc attached to the outer layer of steel components, which plays a preservative purposes.

　　　 Coled galvanized,also called electric galvanized.The zinc quantity it contains is little that only need 10-50g/m2 .Cold galvanized is a process that making a metal or other materials attached to a layer of metal film parts appearance by the application of electrolysis.

The Difference between Above

　　　Anticorrosive Property: Hot dip galvanized is dozens of times of cold galvanizing

　　　Mode of Operation : Hot dip galvanized is in 450-480 degrees in molten zinc liquid of zinc plating;Cold is at room temperature after electroplating plating or other method of zinc plating.

　　　Galvanized Layer Thickness:  Hot dipped galvanized thickness is much larger than cold galvanizing.

　　　Appearance Lubrication Degree: Cold galvanized surface is more  lubrication and beautiful than hot dip galvanized .

　　　Adhesive Force: Hot dipped  galvanizing adhesion is better than Cold galvanized.

     Hot galvanizing technology mainly use range: industrial, building, electrical equipment, chemical equipment, machinery, petroleum, municipal equipment, agricultural equipment, communications equipment, fire equipment, railway, highway traffic equipment, etc.
