A Foundation of Trade Capabilities
RJ Mechanical began in 1996 as a startup mechanical contractor based on a philosophy of providing quality systems at a fair price. Over the decades, we have expanded our shop capabilities and regional footprint while maintaining the core operations that established our reputation in Minnesota and the surrounding areas.
Our business relies on a workforce of long-term employees who maintain our quality standards. By combining this trade experience with investments in automated manufacturing, we ensure that every project meets specified code requirements for safety and structural integrity.
