CUSTOM MARINE METAL FABRICATION IN PASCAGOULA, MS
When a shipyard or offshore project needs a part that does not come off a shelf, JMC Fabrication builds it. Our 50,000 sq ft shop in Pascagoula produces custom marine weldments, equipment foundations, brackets, and structural assemblies, welded by NAVSEA and AWS certified welders and documented to the standard marine and defense buyers require.
Custom marine fabrication covers the one-off and low-volume parts that keep a vessel or yard project moving: equipment foundations and skids, mounting brackets, structural supports, penetrations, ladders and platforms, and weldments built to a customer drawing. JMC takes these from drawing review through cut, weld, finish, and documentation in one shop.
JMC's custom marine scope is built around shipyard and offshore needs:
- Equipment foundations, skids, and mounting structures
- Brackets, supports, and structural weldments
- Penetrations, flanges, and fittings for marine systems
- Ladders, platforms, and access structures
- Carbon steel and 304/316 stainless steel assemblies
JMC's in-house engineering team reviews customer drawings before production, flags fabricability issues early, and goes directly to the shop floor. For custom marine work, where every part is specific to a vessel or system, that review removes the back-and-forth that adds time to a complex package.
- NAVSEA certified weld procedures for marine and Navy spec work
- AWS certified welders across structural and piping work
- NDE documentation per project specification
- Material traceability: MTRs, heat certifications, and weld logs
- Project closeout documentation packages
JMC sits minutes from Ingalls Shipbuilding and the Port of Pascagoula. For custom parts that often ship on short notice to support a build or repair schedule, that proximity keeps delivery practical and turnaround tight.
