The main differences between electro-galvanizing and hot-dip galvanizing are the thickness of the coating, the process, the applicable scenarios and the corrosion resistance.
Coating thickness: The coating thickness of electro-galvanized zinc is usually between 5 and 15 microns, while hot-dip galvanized zinc can have a coating thickness of 60 to 300 microns.
Process: Electrozinc plating uses electrolysis to electrochemically deposit a thin film on a metal surface, while hot-dip galvanizing involves dipping metal products into molten zinc and relying on a chemical reaction to form an alloy.
Applicable Scenarios: Electro-galvanizing is suitable for smaller metal products such as screws and nuts, while hot-dip galvanizing is suitable for metal products of all sizes, including larger steel structures.
Corrosion resistance: Hot-dip galvanizing has strong corrosion resistance and is suitable for a variety of strong corrosive environments such as strong acids and fogs, while electro-galvanizing has relatively weak corrosion resistance and is suitable for occasions that do not require high corrosion resistance or have decorative requirements
