The Aluminum Semi-Rigid Duct manufactured by Samco Flex Ducts® is constructed using a special grade aluminum alloy that prevents corrosion and metal fatigue. The machine fabrication produces a continuous lock seam that allows the duct to be pulled open, bent, compressed and re-bent without developing fatigues or leakages. Our Aluminum Semi Rigid Duct does not de-laminate or die out when it is heat aged and can be installed with severe bends

and in unlimited lengths while maintaining an unrestricted diameter.
