Black and Anthracite Grey available for next working day delivery (order by 11:30am)
Aluminium box guttering is usually chosen when clean lines and performance take priority. It’s sharp, architectural, and deliberately understated - the kind of guttering you notice only because it doesn’t draw attention to itself. On modern buildings it feels obvious. On heritage or mixed-style projects, it can be surprisingly effective when specified carefully.
This collection includes Alumasc box gutter systems, manufactured to a high standard and designed to balance appearance, capacity, and ease of installation. Whether you’re comparing aluminium box guttering prices, sourcing reliable aluminium box guttering suppliers, or specifying a heritage aluminium box gutter for a sensitive project, this range is built to cover those bases. Pairs with aluminium downpipes.
Profile, size & system details
The standard profile we supply in this range is 125 x 100mm, offering generous flow capacity without looking oversized. As a leading aluminium guttering supplier, we decided to include two top fixing straps with each gutter length purchased, keeping the system secure and visually tidy once installed.
The design uses an internal fixed joggle joint, which makes installation simpler than floating joint methods and helps maintain clean external lines.
Longer gutter lengths also reduce the number of joints required — saving time on install and cutting down future maintenance points.

-
Smooth, crisp lines for a modern aesthetic
-
Durable, weather-resistant construction

Factory-applied powder coating for consistent colour and low maintenance

100% recyclable aluminium, making it a more sustainable choice
