Rectangular Downpipe 100×50

The rectangular downpipe 100×50 carries rainwater from the gutter down to the stormwater system at the base of the wall. It is the standard rectangular profile on Australian homes, with a slim 100mm by 50mm shape that sits close to the wall and gives a neat line down the building. The flat face sits flush against the wall, which keeps the run tidy and makes it easier to clear leaves and debris from the top of the pipe. It is made from Colorbond steel and is available in 1.8m and 2.4m lengths.

Colours and Finishes

The downpipe is available in a wide variety of standard Colorbond colours, from light natural tones such as Surfmist, Dune and Paperbark through to dark shades such as Monument, Night Sky and Ironstone. Colorbond is pre-painted with a baked-on finish that resists chipping and fading, so the downpipe keeps its colour for years. A plain Zincalume option is also available where an unpainted, corrosion-resistant finish is preferred, such as on sheds and outbuildings. If you need a colour that is not listed, add it to your order notes and we will confirm availability before dispatch.

Applications

• Re-roofing jobs where the rainwater line is being replaced

What You Need To Complete The Job

Fit the downpipe with the matching fittings so the run is straight and watertight. Fix it to the wall with rectangular downpipe clips 100×50, and use an offset downpipe where the gutter outlet does not line up. Browse the rectangular downpipe range and the downpipe accessories to complete the line.

Frequently Asked Questions

What size is this rectangular downpipe?

This is a 100mm by 50mm rectangular downpipe. The 100×50 profile is the standard residential size and suits most homes, while the larger 100×75 is used where a higher water flow needs a bigger channel. Match the downpipe to your gutter outlet so water flows through without backing up.

What lengths are available?

The downpipe is supplied in 1.8m and 2.4m lengths. Most runs from gutter to ground need two or three sections joined together. Measure the height from the gutter outlet to the drain, allow for the offset at the top and the shoe at the bottom, then work out how many sections you need.

Is it available in Colorbond colours?

Yes. The downpipe is available in a wide variety of standard Colorbond colours to match your roof, gutter and fascia. Tell us the colour you need and we will confirm it is in stock before dispatch.

What clips do I need to fix it to the wall?

Use rectangular downpipe clips in the 100×50 size. Fix the clips to the wall at regular intervals along the run and clip the downpipe into place. The clips keep the pipe straight and stop it moving in the wind.
