Zinc Plating


Zinc coatings prevent corrosion of the protected metal by forming a physical barrier, and by acting as a sacrificial anode even if this barrier is damaged. When exposed to the atmosphere, zinc reacts with oxygen to form zinc oxide, which further reacts with water molecules in the air to form zinc hydroxide. In turn, zinc hydroxide reacts with carbon dioxide in the atmosphere to yield a thin, impermeable, tenacious and quite insoluble dull gray layer of zinc carbonate which adheres extremely well to the underlying zinc, so protecting it from further corrosion.

Benefits and Uses

Zinc Plating is one of the most versatile surface-finishing processes available. Zinc plating is used for a variety of engineering and functional applications. One of the main uses of zinc plating is to improve the corrosion resistance of steel parts. When applied, zinc works to prolong the life of the base metal. The corrosion protection of zinc plating can also be enhanced through a variety of chromate/passivate and seal dip applications. Results in Excellent Corrosion Resistance.

Whether you are walking through a hardware store, looking under the hood of your car, or mowing the grass, you will find zinc plating at work protecting steel from corrosion in the products we use every day. Zinc plating has found wide acceptance as a surface finish throughout all consumer, industrial, and commercial products. Zinc Plating is very common in our daily lives. “Zinc Plating 101”
