Product Description
Spiral Duct,SD
Galvanized Steel Spiral Duct is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lockseam. It has a smooth interior for low friction loss with the grooved seam entirely on the outside. Galvanized Steel Spiral Duct sections can be joined together by an E-Z Flange with Barrel Clamp, E-Z Flange Jr. with Barrel Clamp, Complete Seal System, Spiral Pipe Connector, or Companion Angle Rings. Optional corrugations are available which increase the rigidity of the pipe by approximately 300%. Galvanized Steel Spiral Duct has a resistance to crushing approximately 2 1/2 times that of longitudinal lockseam or welded pipe.
