Spiral Tubing & Fittings

Alpha Tube, based in Dukinfield, Tameside (Greater Manchester), has served the UK’s heating, ventilation, and HVAC sectors since 1982. With a Manchester warehouse fully stocked for trade, installers, and homeowners, they deliver galvanised spiral tubing, complete duct systems, and custom metal fabrication backed by rapid collection and nationwide delivery.

Why Choose Spiral Tubing?

Unlike conventional rectangular ducting, spiral duct:

  • Has fewer joints, reducing air leaks.

  • Offers superior airflow efficiency, especially with its smooth internal finish.

  • Supports continuous temperatures up to 200 °C, and can handle intermittent peaks around 250 °C. (Exceeding these may lead to discolouration and corrosion.)

  • Meets the UK’s DW144 standard, ensuring quality manufacturing and installation.

Galvanised Spiral Tubing

  • Spiral Tubing x 1.5 m: Durable, galvanised, female-sized tubes accepting male fittings. Available in 63 mm–710 mm diameters. Custom sizes via enquiry; 3-meter lengths available for in-store pickup.

  • Engineered for peak durability, corrosion resistance, and airflow efficiency—thanks to galvanized coating and helical design.

Galvanised Spiral Fittings

A comprehensive range ensures seamless system design:

  • Bends: 30°, 45°, and 90° angles with male ends, sizes 63–710 mm.

  • Collars: Male and female collars to join lengths or fittings (63–630 mm).
