Steel downpipes and accessories

CMI are a leading Perth gutters and downpipes supplier. We stock a wide range of steel downpipes and accessories for use in any residential or commercial application. Our stainless steel downpipes are manufactured from high quality  COLORBOND® or ZINCALUME® materials and just like all our other wall and roofing materials, they are made to last and look good for life. 

The correct guttering and downpipes are important for collecting and disbursing water and also protecting the structure of your home. Broken and poor fitting gutters and downpipes can lead to water damage that isn’t always obvious until it starts costing you money.

Our stainless steel downpipes prices are affordable and our products can be cut to 1.8m or 2.4m lengths to suit your needs.
