Commercial & Industrial Construction & Prefabrication

Prefabricating Commercial Mechanical Systems

Commercial Ductwork Prefabrication ServicesWhen designing commercial mechanical systems Southport asks, “what has to be done in the field?” and prefabs everything else. Southport strives to prefabricate any and all mechanical systems to maximize quality, efficiency and project safety.

Our fabrication shop, strategically located on I-94 in Caledonia, WI, has over 50,000 square feet outfitted with state-of-the-art workstations and hoisting equipment for cutting, welding and joining all types of mechanical systems. We utilize galvanized sheet metal, stainless steel, aluminum, fiberglass, black iron and other materials when manufacturing rectangular, round and oval ductwork. Our prefabricated components are exported directly from our models to the shop for construction, ensuring the highest quality and accuracy. All shop fabricated work is inspected and tested prior to shipment. Field supervisors recheck items on-site prior to installation.

With our state-of-the-art equipment and staff of qualified employees, our fabrication shop can fabricate and assemble accurately any type of piping configuration from the simplest riser to complex mechanical and boiler rooms. The shop’s controlled environment enables us to maintain a high degree of quality and a constant level of productivity regardless of weather or project site conditions.
