Zinc Plating Thickness Guidance

What thickness should I use for ...?

The thickness of zinc plating that you should use depends on the environment that the component is in. We have produced some recommendations based on what we find is suitable for most of our customers. The corrosion resistance of the zinc depends on two things:

The protection from the zinc plating is proportional to the thickness of the zinc plating - so thicker zinc means more protection for the base metal. Thickness has almost no effect on the resistance to "white rust" because this involves the coating itself corroding.

Note: In the most corrosive environments,particularly those with a risk of salt spray, zinc plating alone will probably be insufficient. It is suggested that you have the part zinc plated and then paint any exposed areas. We do not recommend powder coating.

Your Purchase Order

Please tell us what thickness you require on your purchase order. We suggest that you specify using the ISO 2081 system (as in table above).
