Spiral Duct

Spiral Pipe – Plain & Wrapped

Rigid round galvanised steel spiral pipe for HVAC, ventilation and air distribution systems.

The spiral-wound construction provides a strong, lightweight duct with a smooth internal airflow path, making it ideal for main duct runs and commercial ventilation systems.

Available plain or externally wrapped with insulation to suit the application.

Plain Spiral Pipe

Plain galvanised spiral pipe provides a strong, rigid duct system suitable for:

• Supply air

• Return air

• Fresh air ventilation

• Exhaust air

• Exposed or concealed duct installations

Its clean galvanised finish also makes it suitable for exposed ductwork where the duct forms part of the finished installation.

Wrapped Spiral Pipe

Wrapped spiral pipe combines the strength of galvanised spiral duct with external insulation.

The insulation helps reduce heat gain or heat loss through the ductwork and assists with condensation control, making it suitable for conditioned supply and return air systems.
