Round Aluminum Semi Rigid Duct
(SAMCO 140)

The Samco Semi Rigid Aluminum Duct is constructed using a special 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 duct does not delaminate or die out when it is heat aged and can be installed with severe bends and in unlimited lengths while maintaining an unrestricted diameter.
