The strength, corrosion-resistant and lightweight properties of Glass Reinforced Plastic (GRP) significantly outperform metallic alternatives.

Strengthening Industry

GRP profiles and rebar offer a lower through-life environmental impact than steel equivalents, with a low maintenance lifespan of over fifty years.

Promoting sustainability

GRP offers many practical benefits, including outstanding strength, corrosion and impact resistance, anti-slip, low maintenance and ease of installation.

Driving performance

Our high performance GRP products deliver exceptional cost benefits long-term.
