The difference between hot dip galvanizing and electroplating
1. Hot galvanizing process:
The iron parts are cleaned and then treated with solvent and immersed in zinc solution. The iron reacts with molten zinc to form an alloyed zinc layer.
The process is: degreasing - washing - pickling - plating Dry - hot dip galvanizing - separation - cooling passivation.
2. Electroplating stainless steel sheet process:
Chemical degreasing → hot water washing → washing → electrolytic degreasing → hot water washing → washing → strong corrosion → washing → electro-galvanized iron alloy → washing → washing → light → passivation → washing → drying.
3. The difference between them:
Hot : thick zinc layer , strong corrosion resistance, high prices.
Electroplating: thin zinc, poor corrosion resistance, low prices.
