Aluminium Hoppers

Aluminium Hoppers

Aluminium hoppers, or hopper heads, are a vital but often overlooked part of an efficient rainwater collection system. They are essentially an open box that sits above the downpipes where the gutters empty the rainwater.

Rainwater hoppers come in various materials, each offering various benefits. Aluminium hoppers are considered a middle ground, offering the benefits of all the other major materials.

Aluminium Superstore has an extensive range of aluminium hopper heads, gutters and downpipes to suit modern and traditional properties.

Functions of Rainwater Hoppers

Aluminium hoppers serve several functions. The hoppers are just for decorative purposes for most people, especially for traditional and heritage projects. But hoppers have other functions as well.


Hoppers are usually added to a gutter system because of the aesthetic appeal they add. This is the case for aluminium hoppers because they feature decorative motifs. The hoppers provide premium space for customisation to add attention-grabbing details and customised motifs or numbers that add uniqueness to the project.

Increasing downpipe capacity

Naturally, downpipes have a water-carrying capacity of about 33%. Most of the space is occupied by air. Adding a hopper increases the capacity of the downpipe to 100% through the siphonic action. The hopper pushes water down the downpipes creating a vacuum that sucks water through the pipe at a higher rate.

Adding a hopper can help solve the problem before installing new and larger gutters if your gutters overflow during a heavy downpour.

Gather a collection of flows into one pipe

You can use hoppers to minimise the need for multiple downpipes, which can negatively affect the aesthetics of the building.

Hoppers allow you to bring together multiple flows into one downpipe. Without the hopper, you will need different downpipes at various roof sections coming together. With the hopper, multiple gutters drain, diverting the water into one downpipe.

Why You Should Buy Aluminium Rainwater Hoppers

Aluminium hoppers strike a balance between functionality and aesthetics. They offer the benefits of cast iron hoppers without the weight and the benefits of galvanised steel with easier installation and more customisation. Some of the reasons why aluminium hoppers are an excellent choice include;


Aluminium is a lightweight material that weighs about a third of cast iron and steel density. The lightweight nature of aluminium makes aluminium hoppers easy to install. The hoppers exert less weight on the fascia board and require less effort to keep in place. The hoppers remain securely in place longer.

Impact resistance

Despite its low weight, aluminium is strong. In case of impact, an aluminium hopper deforms instead of cracking. Although deformed, it ensures continued performance, it doesn't leak or require replacement.

UV light resistance

Like other hoppers, aluminium rainwater hoppers receive a lot of praise for their appealing finish when new. But unlike other hoppers, aluminium hoppers have a high resistance to exposure to UV light. The hoppers don't become brittle or fade because UV light and weather elements are exposed. You can enjoy the attractive finish with aluminium hoppers longer because the colour remains intact.

Temperature and fire resistance

Aluminium properties remain constant with temperature. Aluminium is classified as a non-combustible material. Adding aluminium hoppers to your projects means the hoppers will not melt or spread the flames in case of a fire. At low temperatures, aluminium maintains its properties. In fact, in cold weather, aluminium becomes tougher.

Minimal maintenance

Aluminium rainwater systems are virtually maintenance-free. Polyester powder coated aluminium will need an annual wipe-down with soap and water. In coastal areas, this can be done twice yearly.

Remove leaves and debris to keep your hoppers performing properly, and apply touch-up paint to any exposed metal to avoid corrosion and prolong the service life of your system.

Recyclable and sustainable

It's not just aluminium hoppers, but all aluminium gutters are recyclable. Aluminium's properties don't degrade during recycling, which means the material can be recycled endlessly. Aluminium recycling is highly energy-efficient, making aluminium hoppers a greener and more environmentally-friendly choice.
