GRP Guttering

Ideal as a durable and lightweight replacement for heavy lead or cast iron, our GRP guttering is particularly suitable for traditional and heritage buildings. Manufactured at Yeoman Rainguard’s specialist workshop in Leeds, UK, our dependable GRP guttering can be used for a range of applications, with the material presenting one of the highest strength-to-weight ratios of any construction material on the market.

Durability & Lifecycle

Our GRP guttering products are constructed with glass fibre-reinforced mouldings reinforced with Lloyds-approved resins. Special formulations of laminate provide the desired strength and rigidity, ensuring these products can weather any storm and provide many years of reliable service, with average lifecycles of 30+ years.

Dimensions & Bespoke Shapes

Our GRP gutters are supplied in standard lengths of 1.8m plus spigot; however, the versatile properties of GRP means that other sizes, shapes and profiles are available to order as required.

This adaptability makes our GRP offering ideal for heritage buildings with unique original guttering which requires replacement due to age. Yeoman Rainguard can create a moulding of your existing system to ensure an exact GRP replica.

If you have project drawings or unique guttering shapes/designs, our design team can also assist in bringing these to life in GRP form.

Colours & Finishes
Our GRP gutters are through-coloured, assuring customers that their colour will not chip or fade over time with wear and tear. Coming in a standard black replicating the look of cast iron, our Vision range of colours as well as BS5252 (inc BS4800) or RAL colours are available at a small premium.
