Aluminium Round Downpipes

Aluminium round downpipes offer a timeless architectural look while delivering exceptional durability and efficient rainwater drainage for both period and contemporary buildings. Highly resistant to weather and corrosion, these systems provide a long-lasting, low-maintenance alternative to plastic or cast iron.

Choosing the correct profile diameter ensures your system manages heavy downpours without overspill. Both standard and Smoothline designs are available in five industry-standard sizes:

63mm (2.5") – Best suited for smaller residential projects or domestic extensions.

75mm (3") – The standard choice for average-sized family homes.

100mm (4") – Ideal for larger residential properties or standard commercial roofs.

125mm (5") – Designed for high-capacity commercial and industrial applications.

150mm (6") – Maximum capacity for heavy-duty rainwater management on large-scale buildings.
