China factory fire resistant semi rigid flexible duct 8 inch aluminum flexible duct

Semi Rigid aluminum flexible duct

this Semi Rigid Aluminum Flexible Duct is Constructed of a special aluminum alloy that prevents from corrosion and metal Fatigue. the machine fabrication produces a continuous lock seam that permits the duct to be pulled open, compressed, bent and re-bent without developing Leakage. this semi rigid flexible duct will not delaminate or dry rot when heat Aged. It can be installed with severe bends and in unlimited lengths while Maintaining an unrestricted diameter. the semi rigid aluminum duct comes in Conveniently boxed 5 foot, 10 foot and 15 foot lengths. It is compressed to Nearly 3 times its original length for convenient shipping and handling.
