Three Divisions, One Source


MSM Mechanical

Our core fabrication division handles custom mechanical systems from concept through completion. Whether you need structural frames, precision assemblies, or production runs of identical parts, we have the equipment and expertise to build it right. CNC plasma cutting up to 10' × 40', heavy press brakes up to 325 tons, and full machining capabilities mean we can tackle complex projects without farming out critical operations.

MSM Tanks

As an ASME U-stamp certified shop, MSM Tanks fabricates code-compliant pressure vessels in both mild steel and stainless steel. We know the equipment manufacturers who rely on us can’t afford delays or failures in the field. That’s why every vessel we build meets ASME Section VIII standards and undergoes rigorous testing before it ships. From single custom tanks to production runs for OEM partners, we maintain the same exacting standards.
