Aluminium Guttering

Aluminium guttering is a brilliant alternative to cast iron because it achieves a similar appearance but is cheaper and a more lightweight system. Gutter Warehouse supplies two different aluminium guttering finishes; cast and contemporary. 

Accordion Content

Our Alumasc cast range is to be used on properties that want to achieve a classic heritage appearance, such as listed buildings. Within this range, textured black is available on next working day delivery, and a variety of other aluminium guttering colour finishes are in-stock. The guttering will not rust as the surfaces oxidise to create a natural barrier.

For a more contemporary look on your property, we recommend using the SnapIt half round guttering and SnapIt Express extruded systems. The 3m length gutters and snap-together systems make them easy to install and ideal in areas which are hard to access. We offer a wide range of coatings and finishes.

There are a number of benefits to using aluminium guttering for your project. Below, we outline some of the key advantages:

  • Durability – aluminium is a durable material and will not rust, making it a great long-term choice. It’s life cycle is expected to be upwards of 30 years under correct maintenance. Unlike PVC, you won’t have to replace this rainwater system after a few years! 
  • Aluminium gutters and downpipes will not crack. If you’re in a windy area (e.g. coastal locations like Exeter), you may have debris and sticks attacking the gutters on a regular basis. Aluminium is much stronger than plastic guttering, and it also isn’t affected by temperature changes (i.e. it doesn’t crack). 
  • Little maintenance required – Aside from clearing out leaves from the gutters, little maintenance is required for this system. There is no need to worry about priming, painting or protecting the gutters.
  • Lightweight – Aluminium weighs around 2.7g per cm3, which is approximately 1/3 of the density of steel and cast iron guttering. This makes it easy to install, shape and transport. It’s also why aeroplanes are built using aluminium!
  • Corrosion resistant – did you know that aluminium naturally creates a protective oxide coating when it comes into contact with oxygen? This protects against corrosion and, if it’s damaged, it will regenerate (as long as oxygen is present).
  • A high quality, aesthetic appearance – aluminium gutters are a fantastic addition to your property, and match contemporary facades in urban areas. Get in touch with us for metal guttering case studies for project inspiration.
  • UV Radiation resistant – PVC can suffer from colour fading and cracking, whereas aluminium does not.
  • Eco friendly – Aluminium guttering is 100% recyclable and the re-melting process only requires about 5% of the energy needed in initial production. With the growing threat of climate change, it has never been more important to choose an eco-friendly rainwater system.

It is very likely that your conservation officer will allow aluminium as a cast iron alternative – they are eco friendly and have a similar look.

They are nearly identical. Mouldings of original cast iron products are made to ensure that every detail, including the original sand-cast ‘orange peel’ appearance, is replicated to give a true representation. 

Gutters, rainwater items and fittings are actually “cast,” meaning that collars and lugs also have that original appearance

We think so! Fitting cast iron is likely to be a two-person job as items such as downpipes can be quite heavy. Aluminium is far lighter and easier to fit, which makes it a great choice for residential use where access may be difficult. If you want something really easy, consider the SnapIt range.

Nope! The great thing about this rainwater system is that there is no need to prime or paint the gutters. Aside from cleaning leaves, maintenance is very minimal!
