Construction details:

A rectangular duct can be transported either as complete assembly or as L shape.

Round and Oval ducts are transported as complete assembly.

Longitudinal seams are fabricated with Pittsburgh lock (transverse joint S&C cleat joint). Four bolt connectors are also available.

In order to optimize the construction cost, the length per piece is optimized. This optimization of duct length solely depends on the duct size as specified in the drawing.

TDS duct corners can also be provided at separate cost.
