Square Duct and Rectangular Ducts

We manufacture standard lengths of 1220mm long Square Duct and Rectangular Ducts for the Air Conditioning Industry.



  • Square Ducts and Rectangular Ducts are manufactured using 0.55mm and 0.75mm thick galvanised steel sheets and, depending on the size, these ducts are folded and joined using the Pittsburg joint. The ends are fitted with TDF frames which are 25mm wide. Other size frames can be fitted on request. Sides are cross-broken for extra rigidity.
  • We manufacture Square and Rectangular Transitions and Elbows to any size required.
