Are you searching for the perfect square downpipe for your home or commercial space? When marrying functionality with aesthetics, square downpipes are your top choice. These aren't just regular aluminium rainwater pipes; square downpipes represent the seamless fusion of state-of-the-art design with premium performance.

Dive deep into our collection, designed to cater to diverse architectural needs.

What is a square downpipe?

A square downpipe is a type of rainwater pipe specifically designed with a square profile, rather than the traditional round shape.

It primarily carries rainwater from a building's guttering system down to the ground or into a drainage system. Not only does the square design offer a distinct aesthetic appeal, often chosen to complement modern architectural styles, but it can also provide efficient water flow, depending on the specific needs and design of a building.

Aluminium downpipes vs plastic systems

Choosing aluminium downpipes over plastic systems comes with several advantages.

Aluminium is known for its durability and longevity, unlike plastic. Due to UV exposure and weather conditions, plastic rainwater piping systems can become brittle and discoloured over time.

Aluminium retains its appearance and strength for decades, often with minimal maintenance. This makes aluminium downpipes more cost-effective in the long run. Additionally, aluminium offers a sleeker, more premium aesthetic suitable for modern and traditional architectural styles.

Environmentally conscious builders and homeowners also prefer aluminium as it's 100% recyclable, reducing the environmental impact when it eventually needs replacing.

Aluminium systems typically provide a tighter fit and better sealing, ensuring optimal performance and fewer leaks compared to some plastic counterparts.
