FABRICATION INSIGHTS FROM PASCAGOULA, MS

Practical guidance from JMC Fabrication on pipe spool vs stick-built tradeoffs, material selection, code compliance, and project planning for commercial, marine, and oil & gas work across the Gulf Coast.

• July 22, 2026Commercial Duct Fabrication Lead Times: What Drives Them and How to Compress ThemThe real drivers of commercial duct fabrication lead time and how mechanical contractors can compress it, covering drawings, material, and shop capacity.
• July 15, 2026Rectangular, Round, and Spiral Duct: Choosing the Right Shape for Commercial HVACHow duct shape affects airflow, leakage, space, noise, and cost, comparing rectangular, round, spiral, and flat-oval duct.
• July 8, 2026Galvanized vs. Stainless Steel Duct: Choosing the Right Material for Commercial HVACWhen commercial HVAC duct calls for galvanized and when it needs stainless, covering corrosion, environment, grade selection, and cost.
• July 2, 2026Industrial Exhaust and Dust Collection Duct Fabrication: How It Differs from HVAC DuctWhy industrial exhaust, dust collection, and process ventilation duct is built differently from commercial HVAC duct, and how JMC Fabrication approaches industrial ductwork.
• July 2, 2026Double-Wall and Insulated Duct: When You Need It and How It Is BuiltWhen to specify double-wall or insulated duct, how it is constructed, and the tradeoffs versus single-wall duct with an external wrap.
• July 1, 2026SMACNA Duct Construction Classes Explained: Pressure Class, Gauge, and ReinforcementA plain-language guide to SMACNA duct construction classes covering pressure class, gauge, seams, joints, and reinforcement for commercial HVAC duct.
• May 13, 2026Carbon Steel vs. Stainless Steel Fabrication: Choosing the Right Material for Marine and Industrial ApplicationsHow carbon and stainless steel compare on corrosion, weldability, and cost, and how to choose between them for marine, oil and gas, and commercial HVAC fabrication.
• May 8, 2026Spooled Piping vs. Stick-Built Piping: When Each Makes Sense for Your ProjectA practical framework for when shop-fabricated pipe spools beat stick-built field piping, and the scenarios where field assembly is still the right call.
