Spiral Ductwork and Stainless Steel

Heavy-Duty Industrial Spiral Pipe (3" to 40" Diameters)

Our pipe is built to meet or exceed all SMACNA standards, ensuring structural integrity in both high-velocity HVAC and heavy industrial material handling. The smooth interior reduces friction loss, while the continuous interlocked reinforcing rib on the exterior allows for long runs with fewer joints and hangers.

Whether you require standard galvanized steel for general ventilation or 304 stainless steel for FDA-regulated food processing or chemical applications, we match the material to your environment.

Skip the wait. Speak to a human.
