Queensland Sheet Metal produces round downpipes that come in a range of different diameters to suit both industrial and residential buildings. Lengths are available in a range of Colorbond® Steel colours, Zincalume®, Galvanised, stainless steel and copper, up to 5m.
Available Colours
The Colorbond® steel colour swatches above have been reproduced to represent actual product colours as accurately as possible. However, we recommend checking your chosen colour against an actual sample of the product before purchasing, as varying light conditions, different screens and limitations of the printing process may affect colour tones.

Additional Information
As a general guide, in non cyclonic areas, for every 1m² of roof area drained, 70mm² of downpipe is required. This calculation is based on the assumption that the maximum rainfall does not exceed 125mm per hour.
It is considered the best practice to drain to different points, using smaller downpipes rather than to one large outlet. Where possible, downpipes should be spaced at not more than 12000mm centres.
