Mid-State Engineering is now a RōBEX Company. Exceptional solutions, streamlining processes with state-of-the-art automation and engineering.

It’s all under one roof, a single precision-minded team delivering you the very best. Our engineers create the designs in one room, then hand them over to the metal fabricators and the electricians in the next.

It’s unique in our industry and it’s the thing that makes our work seamless. We bid on a job, we build it under one roof, we deliver on it done right.

We create solutions for global brands with the highest standards for precision and quality. We also create solutions for businesses that aspire to be global who may be taking their first steps into the world of automation.

While our competitors bid on jobs and piece together patchworks of subcontractors, you’ll have confidence when you make a single phone call to us knowing that we can deliver the solution you need from top to bottom.

Our in-house mechanical and electrical engineers work closely with our design engineers and fabrication department to ensure the integration and automation you demand fits your processes precisely.
