Electrogalvanizing is galvanizing through electrode reaction, while hot-dip galvanizing is immersing raw materials into zinc pot for galvanizing, which is an intermetallic reaction and a physical reaction.

When hot-dip galvanizing, the surface of the raw material is a layer of intermetallic compounds, followed by zinc, while the surface of electro-galvanizing is zinc, and there is no intermediate layer.

Electro-galvanized zinc layer is thinner, hot-dip galvanized zinc layer is thicker

Electrogalvanizing cannot be mass-produced, and the output is low, while hot-dip galvanizing can be mass-produced and the yield is high.

The surface condition and corrosion resistance of electroplating are better than those of hot dip galvanizing

Electrogalvanizing is better than hot-dip galvanizing, so the price is also expensive

The cost of electrogalvanizing is high, so the price is high. When the price of zinc-aluminum alloy for hot-dip galvanizing is high, it is more than 4W/ton......

The anti-corrosion principle of electrogalvanizing and hot-dip galvanizing is the same. It's just that the two processes are different.

After electro-galvanizing - smooth surface. Appearance is bright. However, since the zinc layer is attached to the surface, it will fall off after a long time.

Hot-dip galvanizing - some are not as beautiful as electroplating. However, the zinc layer has penetration, and the use time is longer than that of electroplating.
