Aluminium Box Guttering

Our Aluminium Box Gutters, also known as a square gutter or rectangular gutter, are pressed aluminium gutters that are suited to both modern and traditional projects including those where a high capacity gutter is required.

Box gutters are ideal as concealed eaves gutters in conjunction with a wraparound aluminium fascia soffit system. We can manufacture special profile box gutters either fabricated or pressed.

We offer eight standard profile widths of aluminium box gutters and can manufacture an infinite amount of alternative box gutter sizes to suit individual project requirements.

Our standard profile widths are:

  • 100 x 75mm / 4"x3"
  • 100 x 100mm / 4"x4"
  • 125 x 100mm / 5"x4"
  • 150 x 100mm / 6"x4"
  • 150 x 150mm / 6"x6"
  • 200 x 150mm / 8"x6"
  • 200 x 200mm / 8"x8"
  • 300 x 200mm / 12"x8"

Benefits of Aluminium Box Gutters

Our aluminium box gutters offer many benefits as they are easy to install, low maintenance, lightweight yet very robust, with all of our gutter sizes having welded internal brackets. Our gutter jointing system is proven over 25 years.

Easy, fast installation: Our box aluminium gutters have integral welded spigots / butt straps and are double spigotted meaning less joints and less waste of gutter lengths, resulting in faster and easier installations.

Over 90% of the aluminium we use is recycled meaning we offer a sustainable rainwater system for your building project.
