Flushjoint Aluminium Downpipe

Flushjoint aluminium downpipes are a contemporary rainwater solution designed for properties where a clean, minimalist finish is essential. Unlike traditional downpipes, the Flushjoint system utilises concealed spigots, providing the pipe with a smooth, seamless appearance that complements modern architecture. These downpipes are mounted on brackets, allowing them to stand clear of the building structure, providing both visual elegance and functional performance.

Gutter Centre stocks the Alumasc range of contemporary extruded aluminium downpipes, ensuring high-quality, corrosion-resistant performance with minimal maintenance, ideal for both new builds and modern refurbishment projects.

Types of Flushjoint Aluminium Downpipes

The Flushjoint system is versatile, offering several profiles to suit different building aesthetics and drainage requirements:

Flushjoint Circular Downpipes – Classic round profile for curved rooflines and soft architectural lines.

Flushjoint Square Downpipes – Clean, geometric lines suitable for contemporary or commercial buildings.

Flushjoint Rectangular Downpipes – Bold profile ideal for larger properties and modern designs requiring substantial water flow.

Each type is designed for seamless integration with Alumasc gutters and accessories, ensuring a cohesive and visually consistent rainwater system.
