GRP Downpipes

Lightweight and durable, our GRP downpipes are ideal as a cost-efficient replacement for old guttering on heritage buildings. Manufactured at our specialist facilities in the UK, our GRP products are a sturdy downpipe solution coming in a range of available sizes as well as square, rectangular and circular profile options.

Dimensions & Material Specifications

Our GRP downpipes are manufactured in 1.8m and 0.9m lengths as required, coming complete with sockets for ease of installation. All of our GRP pipes are glass fibre reinforced mouldings impregnated with Lloyds-approved resins, whilst special formulations of laminate provide the desired strength and rigidity.

Colours & Finishes

All of our GRP downpipes are through-coloured, ensuring that their chosen colour does not fade or chip over time due to wear and tear. Coming in a cast iron black as standard, these can be ordered in custom colours at a premium, including the Vision colour range as well as BS5252 (inc BS4800) or RAL colours.
