Serving Minnesota

PE-led engineering for Minnesota industry

Minnesota's industrial base includes Iron Range mining operations, chemical manufacturing, and a large food and beverage processing sector. These facilities require engineering partners with ASME code expertise and experience with steam systems, refractory, and pressure vessel work.

Grey Engineering Enterprises serves Minnesota clients with steam plant engineering, pipe stress analysis, ASME pressure vessel fabrication, and refractory and acid brick installation. Our experience at Iowa mining and chemical processing facilities is directly applicable to Minnesota's similar industrial environment.
