105mm Cascade Cast Effect Round Downpipe

Explore our range of Brett Martin 105mm cast iron effect downpipes, designed for seamless integration with the industrial Deepstyle 170mm guttering system. These downpipes boast a traditional round profile and are available in eight heritage colours to meet the design specifications of your project. 

Order today to take advantage of competitive pricing and streamline your next installation. A 100mm x 75mm rectangular downpipe is also available if you prefer a more contemporary profile to complement your Deepstyle guttering. 

Invest in Efficient Cast Iron Effect Downpipe

Downpipes are essential for channelling water from gutters into drainage systems and protecting buildings from water damage. This duty is vital in areas with heavy rainfall or on buildings with large roofs, as inadequate drainage can lead to leaks, erosion, and significant structural damage.

If you’re working on a heritage restoration or a period-style property that requires superior protection, consider Brett Martin’s Cascade cast iron effect range. This collection features high-capacity drainage components made from modern PVCu, designed to replicate the classic look of traditional cast iron. Installing these products allows you to upgrade and safeguard your building without compromising its historic character.

 

Use a 105mm Downpipe to Complete Your High-Capacity System. 

For the most high-capacity applications, Brett Martin recommends Deepstyle 170mm guttering, which integrates perfectly with the round cast effect 105mm downpipe. Purchase lengths of 1.8m downpipe and compatible components, such as clips, branches, bends and couplers from Drainage Central. All pipes and fittings feature convenient drilled lugs and traditional cast iron effect collars for a functional and aesthetically pleasing finish.
