The Difference Between Hot Dipped Galvanized and Cold Galvanizing



Galvanizing: also called hot dip zinc and hot galvanizing, is an effective way of metal corrosion protection, mainly used for metal structure industry facilities. around 500 ℃ after rust removal of steel in zinc melt liquid, make the zinc layer is adhered on the surface of the steel members, thereby the purpose of anticorrosive.

Cold galvanized is aso called electric galvanized, zinc quantity is little, only 10-50 g/m2, is to use electrolysis to make metal or other material adhered on the surface of the parts of a layer of metal film process. Formation uniform, compact, good adhesive force of metal layer can prevent corrosion, the process of improving wear resistance, electrical conductivity, reflective and enhance

The difference between hot dip galvanized and cold galvanizing:

 1, anticorrosive, hot dip galvanized is dozens of times of cold galvanizing.

2, vary in their manner of operation: hot dip galvanized is in 450-480 degrees of molten liquid zinc in zinc plating, plating is cold at room temperature by electroplating of zinc plating or other methods.

3, galvanized layer thickness is different, hot dip galvanized thickness is much larger than cold galvanizing.

 4, surface smoothness, cold galvanized than galvanized smooth good-looking appearance. Price is higher than

5, the price is different, hot dip galvanized cold galvanizing.

6, cold galvanized can only side plating, hot dip galvanized for plating.

7, adhesion, adhesion of cold galvanizing is inferior to hot dip galvanized.

8, fee standards is different, hot dip galvanized according to the thickness of the material fee, cold most of the plating charge according to square meters.

 Hot galvanizing technology mainly use range: industry, construction, electric power, chemical industry, machinery manufacturing, petroleum, municipal facilities, agricultural facilities, communication facilities, fire facilities, railway, highway and transportation facilities and other fields.
