Alumasc Rainwater

Alumasc Rainwater is the UK market leader for Aluminium, Cast Iron and Steel gutters and downpipes. From cutting edge-contemporary to traditional heritage, Alumasc’s metal rainwater systems outperform others whatever the weather.

With a unique range of profiles, finishes and made-to-order options, we manufacture each metal system to the highest standard for strength, long life and durability.

Our Aluminium rainwater is BBA accredited and suitable for traditional and modern buildings. The range includes Cast, Pressed and Extruded systems and is lightweight, low maintenance and corrosion resistant.

Alumasc’s Cast Iron rainwater is popular for many heritage and period properties in the UK. Available in black and seven Heritage colours, it looks great, and is durable, incredibly strong and 100% recyclable. Our fully factory painted cast iron rainwater is Apex certified, which involves a unique water based three coat system factory-applied under strictly controlled conditions. This means the protective paint is applied to a far higher standard than possible on site so our products perform significantly better and longer.

Our Steel rainwater is long lasting, eco-friendly, immensely strong and easy to install. It is a high capacity gutter system available in polyester pre-coated black, galvanised finish or a range of six popular colours. It’s surprisingly affordable and ideal for domestic new build or refurbishment projects.
