About GRP

What is GRP?

GRP — glass-reinforced plastic, also known as fibreglass or GFRP — is a composite material made from a thermoset polymer matrix reinforced with continuous glass fibres. The combination produces a structural material that is light, strong, corrosion-resistant, electrically non-conductive and dimensionally stable across a wide temperature range.

Most of our GRP products are manufactured by pultrusion, a continuous process that delivers consistent mechanical properties and tight tolerances. The result is profiles, grating, platforms and handrails that perform reliably for decades in environments where steel corrodes, wood rots and aluminium is too soft.

Why choose GRP over steel, aluminium or wood?

• Corrosion resistance. GRP does not rust and withstands salt water, chlorides and most acids and alkalis — ideal for water treatment, marine and chemical industries.
• Light weight. Roughly 1/4 the weight of steel and 2/3 the weight of aluminium, which lowers transport cost, simplifies installation and reduces structural load.
• High strength-to-weight ratio. Pultruded GRP profiles carry significant loads without heavy substructures.
• Electrical and thermal insulation. Non-conductive — preferred for rail infrastructure, substations and electrical environments.
• Low maintenance. No painting, no galvanising and no cathodic protection.
• Long service life. Designed for 25+ years in harsh environments, reducing total cost of ownership.
• Safety. Anti-slip surfaces and fire-retardant resins meet demanding industrial requirements.

Common applications

GRP is used for industrial walkways, platforms and stair treads, handrails and guardrails, structural beams and columns, cable management, gratings for wastewater plants, jetties and pontoons, wind turbine service platforms, and pedestrian access in rail and metro environments. Wherever corrosion, weight or electrical safety is a concern, GRP outperforms traditional materials.

Sustainability

Our GRP products are supplied with third-party verified Environmental Product Declarations (EPD). A long service life, low maintenance and lightweight transport reduce embodied carbon over the lifecycle compared to steel and concrete alternatives.
