Aquaduct Industrial Seamless Guttering

Why seam-less makes the others seem less? Because seams are the primary cause of corrosion and expensive gutter failure. Aquaduct has done away with them. Aquaduct's versatile roll forming system manufactures seam-less gutters on site to almost any profile, in a range of corrosion resistant metals, that ensure years of maintenance free operation. Because Aquaduct's seamless relining of corroded guttering lasts five to ten times longer than any other system, it is obviously also highly cost effective.


  • Seamless means: jointless, which means no rusting joints
  • Labour saving: means cost effective, means maintenance free
  • Use of corrosion resistant metals means: dramatic increase in life expectation up to 40 years
  • Industrial gutters produced on site in any required length.
  • No interruption of client's company daily work.

  • Falls are determined when installing and is site specific
  • Galvanised steel holderbats are suspended from the purlins according to the required fall using galvanised thread bar.
  • PVC pipes are hoisted into desired positions and fastened
