Industrial and Commercial Contracting Since 1996

RJ Mechanical, Inc. serves Minnesota and the surrounding regions with large-scale project execution and off-site manufacturing. By moving complex assembly workflows away from the job site and onto our automated fabrication floor, we provide general contractors and facility managers with predictable schedules, strict quality control, and reduced field risks.

Our teams work on heavy industrial facilities, large-scale commercial developments, and high-purity process environments. We execute demanding project specifications, including high-pressure steam networks, certified code welding, and specialized utility piping systems.
