The ZJ Difference

— PRECISION MANUFACTURING —
<ZJ Industries Copper Products

Family-Owned. American-Made.
Three Generations Deep.

Since 1991, we've been doing things differently. While other manufacturers expanded into warehouses and added layers of management, we stayed lean. We stayed family.

"You'd think we have a team of 100 employees, but we're a little bigger than a baker's dozen of dedicated craftspeople. That's the magic: small footprint, massive output."

When you work with ZJ, you're not just another transaction. You're sitting down for a cup of coffee with people who genuinely care about solving your manufacturing challenges. Our customers become part of the family.

With over 90 years of combined experience between our team, we've seen it all. From automotive assembly lines to cutting-edge data centers, we adapt, we innovate, and we deliver—every single time.
