1, corrosion resistance is different, hot-dip galvanizing is dozens of times of cold galvanizing.
2, the way of operation is different: hot dip galvanizing is zinc in 450-480 degree molten zinc. Cold plating is galvanized or other zinc plating at normal temperature.
3. The thickness of zinc coating is different, the thickness of hot-dip galvanizing is much larger than that of cold galvanizing.
4, the surface smoothness is different, cold galvanized appearance is better than hot galvanizing smooth.
5, the price is different, the price of hot-dip galvanizing is higher than that of cold galvanizing.
6, cold galvanizing can only be plated on one side, hot dip galvanized to be fully plated.
7, adhesion is different, cold galvanizing adhesion than hot galvanizing.
8, the charging standard is different. Hot dip galvanizing charges according to the thickness of the material. Most of the cold plating is charged according to the square meter.
