Metroll Round Downpipe

The Metroll round downpipe carries rainwater from the gutter down to the drain at the base of the wall. The smooth round profile keeps water moving fast and gives less surface for leaves and debris to catch on compared with some square profiles. It is supplied in Colorbond or Zincalume steel and comes in 75mm, 90mm and 100mm diameters in 1.8m and 2.4m lengths.

Colours and Finishes

The round downpipe is available in a range of standard Colorbond colours so it can match your gutter, fascia and roof, plus a plain Zincalume option. Colorbond is pre-painted with a baked-on finish that resists chipping and fading, while Zincalume has a metallic coating that resists corrosion without paint. If you need a colour that is not listed, add it to your order notes and we will confirm availability before dispatch.

Applications

• New homes and additions that need a clean rainwater line
• Sheds, garages and outbuildings
• Commercial and industrial buildings with exposed downpipe runs
• Re-roofing and gutter replacement jobs where the downpipe is being renewed

What You Need To Complete The Job

Fit the round downpipe with the matching fittings so the run is straight and watertight. Fix it to the wall with round downpipe clips in the same diameter, use a downpipe offset or pop clip where the outlet does not line up, and finish the base with a shoe or rainhead as the job needs. See the full round downpipe range and the downpipe accessories to complete the line.

Frequently Asked Questions

What sizes does this round downpipe come in?

This downpipe is available in 75mm, 90mm and 100mm diameters. The 90mm size is the most common for a single-storey home with a standard gutter, while 100mm suits larger roof areas or long gutter runs. Choose the diameter that matches your gutter outlet so the 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 the downpipe available in Colorbond colours?

Yes. The round downpipe is available in a range of standard Colorbond colours to match your gutter, fascia and roof, and it is also available in plain Zincalume. 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 round downpipe clips in the same diameter as the downpipe. 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.
