  • 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.
