Spiral Duct
Machine-wound spiral-seam circular air duct — low pressure loss and a clean appearance.
What Is Spiral Duct?
Spiral duct is a circular air duct manufactured by winding sheet metal into a spiral shape on a machine and joining it with a locked seam. The circular cross-section provides lower friction loss and quieter airflow than rectangular duct at the same flow rate.
Areas of Use
Preferred in warehouses, production facilities, sports halls, and industrial buildings where exposed installation is not an aesthetic concern. Manufactured in galvanized, stainless, or painted sheet options in accordance with the TS EN 1506 standard.
