Semi rigid flexible duct
This semi rigid aluminum ducting is an all metal flexible duct that
is constructed entirely without the use of adhesives. The lock
mechanical joint makes an air tight seam, while the circumferential
corrugations provide excellent strength and flexibility.DEC
aluminum ducting provides an ideal solution to the problems
inherent in most cloth flexible duct.
Semi rigid insulated aluminum flex duct has much lower pressure
loss than conventional cloth ducts due to the small but consistent
corrugations that provide both strength and flexibility.

This semi rigid aluminum flexible duct is made from dead soft pure
aluminum sheet, as the material has natural vibration damping
characteristics, the installed duct will not transmit vibration.
Strong, highly puncture resistant
Self supporting, eliminates hangers
Complies with all applicable standards
By using a full set of automated production line of nerthland Group
and its product specifications and manufacturing techniques,
manufacture nine major species ventilation flexible ducts, such as
Aluminum foil duct,Combined PVC and AL foil duct,Insulated duct and
acoustical and thermal ducts applying for ventilating and
exhausting systems in high, medium or low pressures, or erosive,
high-temperature, heat-insulation environments.
For more than twenty years of development in Asia, now our company
focus on supplying high quality flexible ducts to a variety of
industries such as building, nuclear energy, military, electron,
space transportation, machinery, agriculture, steel refinery in
China or overseas market.
Wherever there is gas transportation, there will appear our
products. Dec Beijing have already become one of the leaders in
domestic construction ventilating and industrial flexible ducts.
