Frequently Asked Questions

What is zinc plating and how does it work?

Zinc plating is an electrochemical process that deposits a layer of zinc onto steel surfaces. Parts are immersed in a plating bath and exposed to direct current, creating a protective coating that prevents corrosion.

What are the benefits of zinc plating?

Zinc plating provides corrosion protection, extends the life of steel components, and offers a cost-effective finishing solution. It is widely used in automotive, aerospace, and industrial applications.

What specifications does Rayco meet for zinc plating?

Rayco Metal Finishing performs zinc plating in accordance with ASTM B633 and supports additional industry standards to meet strict compliance requirements.

What types of parts are best suited for zinc plating?

Zinc plating is ideal for steel components that require corrosion protection, including fasteners, automotive parts, firearms components, and precision-machined parts.

How do I know if zinc plating is the right process for my project?

If your application requires corrosion protection for steel components in a cost-effective manner, zinc plating is often the best solution. Rayco can help determine the appropriate finish and specification for your needs.
