Galvanised spiral ducting, spiral tube and ductwork fittings for commercial, industrial and HVAC ventilation systems across the UK.
Our spiral ducting tube is available in a wide range of diameters, with matching bends, reducers, branches, dampers and other spiral duct fittings. Our ductwork complies with DW144, the recognised UK specification for sheet metal ductwork.
Spiral ductwork provides an efficient way to supply fresh air and extract stale or contaminated air from buildings. Its circular construction and long 3m tube lengths reduce the number of joints required compared with rectangular ductwork, helping to minimise air leakage throughout the system.
We supply a large range of spiral ductwork products including 45° bends, 90° bends, 60° bends, Y pieces, T pieces, reducers, saddles, shoes & boots, volume control dampers, blast gate dampers, round access doors and flat access doors.
Our galvanised spiral ducting is suitable for commercial ventilation, industrial extraction and HVAC installations where reliable airflow and reduced leakage are important. Spiral ducting can carry air at temperatures of around 200°C continuously and around 250°C intermittently. Using it above the recommended temperatures may result in discolouration or corrosion.

We supply spiral tube and duct fittings in a wide range of sizes, helping contractors, installers and facilities managers source complete spiral ductwork systems from a UK supplier. Products not listed online may also be available.
