COMMERCIAL METAL FABRICATION & HVAC DUCT
JMC Fabrication is the Gulf Coast's commercial HVAC duct and metal fabrication partner for general contractors, mechanical subcontractors, and EPC firms on large-scale commercial projects. SMACNA-compliant fabrication. In-house Revit BIM engineering. 50,000 sq ft of production capacity in Pascagoula, MS. We supply at the scale and documentation level that Tier 1 commercial contractors require.
Commercial HVAC duct is JMC's highest-volume commercial product and our primary growth focus. We produce:
- SMACNA-compliant galvanized steel duct (rectangular, round, oval, all classes)
- High-volume production capacity for large commercial mechanical packages
- Revit BIM engineering coordination — work from GC or mechanical sub Revit models
- Southeast delivery reach that keeps freight economics practical for commercial duct buyers
Duct is bulky. Sourcing it regionally from JMC's Pascagoula shop rather than from out-of-state suppliers saves significant freight cost on large commercial packages — a real economic advantage for Gulf Coast and Southeast buyers.
JMC's in-house engineering team plugs directly into the commercial project coordination process:
- Revit BIM clash detection and drawing review against customer models
- Shop drawings generated from customer packages or JMC-drafted in-house
- RFI support for GC and mechanical engineer coordination
- Duct layout review and optimization before fabrication begins
Beyond duct, JMC's fabrication shop supports broader commercial project needs:
- Structural steel components, frames, and assemblies
- Penetrations, sleeves, and structural supports
- Custom sheet metal work for architectural and utility applications
- Equipment packages and subbases
- Shop-fabricated duct and metal for faster field installation and lower field labor
- SMACNA and AWS certified — required by most commercial mechanical specifications
- Consistent quality and documentation across large, multi-phase projects
- Pascagoula-based: Southeast delivery advantage for commercial duct
- In-house engineering reduces coordination friction with GC teams
JMC operates a 50,000 sq ft facility in Pascagoula, MS with in-house engineering, fabrication, quality inspection, and delivery coordination. The shop is sized for large commercial packages and scalable for multi-phase projects.

Does JMC Fabrication produce SMACNA-compliant HVAC duct for commercial projects?
Yes. JMC fabricates commercial HVAC duct in compliance with SMACNA standards, including proper gauge selection, seam types, and reinforcement per duct class and static pressure rating. SMACNA compliance is a baseline requirement on virtually all commercial mechanical specifications.
Can JMC coordinate with our mechanical engineer or Revit model?
Yes. JMC has in-house CAD/CAM engineering with Revit BIM modeling capability. We can review and clash-check against your mechanical model, generate shop drawings, and provide RFI support throughout the project.
Does JMC provide certified documentation for commercial fabrication projects?
Yes. JMC provides inspection records and documentation packages for commercial projects that require quality sign-off. AWS certification and SMACNA compliance are documented per project.
What commercial project sizes does JMC typically handle?
JMC's 50,000 sq ft Pascagoula facility is sized for large commercial duct packages. Contact JMC with your project scope and timeline — we'll confirm capacity and lead time.
Why source commercial duct from a Gulf Coast fabricator instead of a national supplier?
Duct is bulky — freight costs are a real factor on large commercial packages. Sourcing regionally from JMC's Pascagoula shop keeps freight costs down for Gulf Coast and Southeast buyers while delivering the same SMACNA compliance and documentation you'd expect from a national supplier.
