What follows describes each of them and their uses.

1.Yellow zinc plating

This particular zinc coating is most seen in the automobile industry and offers a middle level protection against rust and corrosion. This plating is ideal for use outdoors due to its substantial anti-corrosive properties.

2. Blue/clear zinc plating

This type of zinc plating generally offers a lower level of corrosion protection, however it has the advantage of being more environmentally friendly than its counterparts. Blue or clear zinc plating is largely used for machine parts, washers, screws and for ornamental purposes due to its attractive finish.

3. Black zinc plating

Black zinc is a metal plating using either black oxide, actual black plating, or both. With a finish ranging from olive drab to pure black, this zinc coating will provide a more intense rust resistance, particularly when black oxide is used. Due to its dark finish, it is often used decoratively.

4. Acid zinc plating

Acid zinc plating is different from the other metal electroplating methods as it doesn’t introduce cyanide into the plating bath. This method is more effective for hard-to-place surfaces, with a superior covering power.
