Oblong rigid spiral ducts: CSRO
The oblong duct is a galvanised steel duct, which is a high-performance alternative to rectangular ducting enabling high airflows in limited spaces (suspended ceiling), or with visible attachment in commercial and multi-occupancy residential buildings. The oblong duct is straight galvanised steel sheet, shaped into its L x H dimensions by forming and calibrating a circular duct on a hydraulic press.
