Frequently Asked Questions


What types of metal do you offer?

Protocase manufactures enclosures, parts and components from virtually any metal. Standard stock materials include steel, stainless steel, galvanneal, and aluminum. See our Materials, Components, and Finishes page for more information.

Can I use copper in my design?

We stock copper alloy C110, which is a general purpose copper designated in ASTM Standard B152. C110 has very high conductivity along with exceptional formability, and is thus ideally suited for electrical and electronic applications. Copper is most commonly used in copper bus bars, as well in other applications. View our Copper web page for more information.

Do you work with plastics?

We can work with plastics in terms of our CNC machining, or by installing clear windows on a custom sheet metal enclosure. We do not stock plastic as a material, however, we can special order it for you as required. For more information, please email
