JWD Sectional Aluminium Rainwater Systems are tough, efficient, attractive and durable, as well as light and easy to install. They offer many advantages over ferrous and plastic systems, such as lightness, great looks, corrosion resistance and flexibility in design and manufacture. Unsurprisingly, aluminium rainwater systems are now the preferred choice for much modern architecture.


JWD is one of the UK’s leading manufacturers of sectional aluminium gutter profiles, rainwater pipes and hoppers, perfect for traditional, heritage and contemporary applications.

The range includes castings, extrusions and profiles, and incorporates designs which can be integrated and concealed in roof-edge systems. All products are supplied in ‘mill finish’ or treated with polyester powder coating, which is available in a wide range of colours to match or complement other architectural features. JWD’s technical staff are also on hand to offer expert help with design advice and product information.
