Spiral Tube & Fittings
Spiral galvanised ductwork & fittings in a large range of sizes.
Our ductwork complies to DW144 standard. The UK recognised specification of how to manufacture and install ductwork. Spiral ducting is made for transporting air - it supplies fresh air into buildings and extracts excess/stale air out of buildings. Spiral duct is much more effective in terms of less air leaks then rectangular ducting due to less joints because of its large 3m lengths. Spiral ducting can be used to carry air up to temperatures of around 200âŚc at a continual temperature and around 250âŚc if the temperature is intermittent. If used above recommended temperatures, discolouring can happen and corrosion can occur.
