Rectangular Cast Aluminium Downpipe

Rectangular cast aluminium downpipes provide a traditional cast iron appearance with the benefits of lightweight, corrosion-resistant aluminium. Designed for heritage restorations, listed buildings, and high-quality new builds, these downpipes strike a balance between aesthetic appeal and long-lasting performance.

Part of the Alumasc Heritage range, rectangular downpipes are crafted to replicate classic cast iron detailing while offering the advantages of modern aluminium. We also stock round and square downpipes, allowing you to maintain architectural consistency across different rooflines and building styles.

Our rectangular cast aluminium downpipes are available in diameters ranging from 63mm to 150mm, catering to a variety of rainwater capacities and property requirements. Supplied in 1m, 2m, and 3m lengths, they offer flexibility for both small and large-scale projects, ensuring a seamless and professional installation.

At Gutter Centre, you can create a full aluminium gutter system to complement your rectangular downpipes. Our range of components includes:

Matching gutters to suit your downpipe profile

Stop ends for neat terminations

Hopper heads for decorative and functional water flow

Brackets, clips, and accessories for secure installation

This ensures a cohesive and durable rainwater system with components designed to work together seamlessly.
