Advantages of electro galvanized steel:
1. Thin coating: The zinc layer in electro galvanized steel is thinner than that in hot-dip galvanizing, typically ranging from 5 to 20 micrometers. As a result, the surface is smooth and does not alter the dimensions or shape of the steel.
2. Uniformity: The zinc coating is uniform and can be applied to the surfaces of objects with complex shapes, such as screws and nuts.
3. Low Cost: The production cost of electro galvanized steel is relatively low because it does not require heating and cooling, unlike hot-dip galvanizing.
4. Environmental friendliness: The electro galvanized steel process does not produce exhaust gases or wastewater, resulting in a minimal environmental impact.

Disadvantages of electro galvanized steel:
1. Poor corrosion resistance: The zinc coating in electro galvanized steel is thinner than that in hot-dip galvanizing, so its corrosion resistance is relatively poor; it is particularly prone to rusting in humid and corrosive environments.
2. Poor wear resistance: The zinc coating in electro galvanized steel is thinner than that in hot-dip galvanizing, resulting in relatively poor wear resistance; it is prone to scratches and abrasion.
3. Limited scope of application: Electro galvanized steel is typically used for steel products in indoor settings and mildly corrosive environments, such as furniture, appliances, and automotive parts.
