The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

Hot dip galvanizing is to remove oil from the workpiece, pickling, dipping, drying after dipping into the dissolved zinc solution for a certain time, can be brought out. Hot dip galvanizing is an effective way to prevent corrosion of metal. It is mainly used for metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anti-corrosion. The galvanized layer is more firm.
