ROUND DUCT PRODUCTS

Our spiral pipe is formed from continuous coils of metal, using a 4-ply lockseam. This results in a very high strength to weight ration allowing for use on low, medium and high velocity air systems of either negative or positive pressure. Our standard spiral duct is available in even diameters from 4” to 80”, 26 to 16 gauge and lengths up to 20’.
