What is difference Between Hot Dip Galvanized Steel And Electro Galvanized Steel ?

1.Appearance difference；
2.The surface of electro-galvanized steel is smooth, dense, beautiful and shiny without zinc flower；
3.The surface of the hot-dip galvanized steel is uneven, rough and uneven, shiny and white. Some products have zinc flowers and knocking may because the zinc-iron alloy layer to fall off in small pieces ;
4.Application range difference；
5.Electro-galvanized is suitable for small parts；
6.Hot dip galvanizing is more suitable for large parts ;
7.Zinc coating thickness and weight difference；
8.The thickness of the electroplated zinc layer is about 10um, the zinc layer is thin, and the adhesion is weak; the minimum galvanized amount is 15g / m2 and the maximum is 100g / m2；
9.The thickness of the hot-dip galvanized zinc layer is about 60um, the zinc layer is thick, the adhesion is strong, and the zinc layer is not easy to fall off; the minimum amount of galvanizing is 40-60g / m2 on both sides and the maximum is 600g g / m2 ;
10.Corrosion resistance and zinc coating structure difference；
