Custom Ductwork Fabrication

Precision. Efficiency. Built In-House.

When commercial HVAC projects rely on exact specifications and consistent performance, the fabrication process becomes one of the most critical parts of the job. That’s why SMCI has centered our capabilities around the advanced production power of our new Vicon Coil Line. This technology allows us to fabricate custom ductwork with greater speed, accuracy, and material efficiency—directly in-house, where we maintain full control over every detail.

By producing our own ductwork and sheet metal components on the coil line, we eliminate common delays, reduce waste, and deliver tighter tolerances that ensure a precise fit on every installation. The result is a higher-quality final product, faster turnaround for our customers, and long-term performance built into every system. This investment represents the continued evolution of our commitment to innovation, craftsmanship, and dependable results across all commercial applications.

Advanced Coil Line Fabrication for Commercial Projects

With our state-of-the-art coil line technology, SMCI can produce custom duct and fittings on demand, allowing our teams to maintain project schedules without relying on third-party suppliers. Automated cutting, forming, and processing ensure that every component is built to exact specification, reducing installation time and minimizing field adjustments. By keeping fabrication in-house, we maintain full oversight of production quality and help mechanical crews deliver reliable results from the first phase of construction through final system commissioning.

This capability supports a wide range of projects, including large-scale design-build installations, plan-and-spec work, retrofits, expansions, and specialized commercial upgrades. No matter the size or complexity of the job, our fabrication division plays a key role in keeping projects on time, on budget, and aligned with mechanical design requirements — all without sacrificing craftsmanship.

Custom Fabrication for Contractors and Trade Partners

In addition to supporting our internal mechanical teams, SMCI’s Sheet Metal Division now provides complete duct fabrication services for outside contractors, HVAC companies, and general builders. With the capabilities of our advanced Vicon coil line, we can produce everything from a single custom fitting to a full duct system package with the accuracy, consistency, and turnaround times today’s projects demand.

We fabricate:

• Standard and custom rectangular ductwork
• Fittings, transitions, and plenums
• Lined and unlined duct sections
• Specialty sheet metal and architectural pieces

Every order is produced using modern Vicon automation paired with the craftsmanship of our union-trained fabricators. Backed by more than four decades of experience, SMCI ensures each component meets precise measurements and performs reliably in the field. Contractors rely on us not only for speed, but for components that arrive ready to install — reducing delays, minimizing jobsite adjustments, and keeping project workflow moving efficiently from start to finish.
