Wholesale Ductwork in Wausau, WI

Central Wisconsin’s building season is short, and HVAC contractors around Wausau have a narrow window to get ductwork hung before interior trades and winter weather close in. Southport Mechanical builds rectangular duct, spiral pipe and custom fittings inside our 45,000-square-foot facility, giving mechanical contractors and builders fabricated components that go up fast and match the drawings.

Benefits of Buying Fabricated Duct From a Commercial Shop

Field-built duct ties up skilled labor and stretches schedules. Sourcing fabricated components lets your crews focus on installation.

• Faster installation comes from hanging finished sections and fittings instead of building them on the jobsite.
• Accurate fit follows from fabrication on shop equipment built for commercial sheet metal.
• Lower field labor costs help contractors bid tighter and protect margins on fixed-price work.
• Cleaner jobsites result when cutting and forming happen in the shop instead of on the floor.

Commercial Ductwork Fabrication and Supply

Every order is built from the information you provide, whether that is a full set of mechanical drawings, coordinated shop drawings or a field-measured list of sizes and fittings. Before production starts, our team reviews dimensions, gauges and connection types and flags anything that looks off so problems get solved on paper. Our fabricators also build duct for our own commercial HVAC installations, so they know what installers need when components reach the ceiling.

Products we fabricate:

• Rectangular duct for supply, return, and exhaust mains and branches.
• Spiral pipe for exposed runs in warehouses, gyms, retail and open offices.
• Fittings and transitions such as elbows, offsets, tees, wyes, reducers and equipment plenums.
• Prefabricated assemblies built and labeled in the shop for faster hanging.

Material and gauge are selected for the system pressure and the environment. Industrial exhaust, washdown areas and high-moisture spaces common in food processing and paper plants may call for heavier gauges or materials other than standard galvanized steel, and we match the build to the specification.

Large orders are routine. A quarter-million-square-foot Woodman’s store in Racine ran on spiral and rectangular duct out of our shop, and a new STEM school in Kenosha received most of its duct and VAV controls prefabricated.

Orders for New Buildings

For new construction, we release duct in the sequence your crews will install it, which keeps material off the floor until it is needed and reduces damage on site.

Retrofit and Tie-In Components

Equipment replacements and renovations often need transitions that adapt new units to existing duct. We build those from field measurements so the connection fits without rework. That matters on winter change-outs, when a building cannot sit without heat while a crew trims and patches a transition by hand.

Corrections for Existing Systems

Airflow complaints, noisy runs, and leaking seams can often be solved with resized branches, new fittings, or replacement sections. Our team helps identify the problem, measures the existing runs, and fabricates the fix.
