Air Handling Systems manufactures premium Galvanized and Stainless Spiral Pipe in diameters from 3″ to 36″, utilizing 18, 20, 22, and 24 gauge galvanized steel and 20 gauge stainless steel. Engineered for superior durability, our pipe features a 4-ply spiral lockseam reinforcement that makes it 20% stronger than smooth pipe and provides 2.5 times the crushing resistance of welded or longitudinal lockseam pipe. This rigid design ensures a smooth interior for low friction loss and requires no painting, lasting years even in outdoor environments. Please note: All 22-gauge pipe measures 1/16″ less than the noted diameter on the inside (I.D.) for precise fitting.
Ideal for dust collection, industrial ventilation, spray booths, and clean rooms, our pipe is available in 5-foot and 10-foot lengths to suit your installation needs. Using 10-foot lengths for long runs can reduce connections by half, significantly lowering installation time and labor. For convenient logistics, 5-foot lengths up to 16″ diameter ship via UPS or FedEx Ground, while larger sizes (18″+) ship via common carrier. Contact us for pricing and fabrication lead times.
