    GRP Profile

    GRP profile that’s up to 50% stronger than the competition – lower your material costs without compromising strength

    Our Glass Reinforced Polymer (GRP) profile offering, d² Dura Profile, is a collection of heavy duty, corrosion resistant fibreglass profiles suitable for a wide range of applications. GRP’s ability to guard against deterioration from industrial chemicals and environmental factors make it a logical and cost-effective alternative to carbon, steel, aluminium, wood or other traditional materials.

    However, not all composites are created equal. There are multiple factors that influence performance, from fibre orientation to manufacturing precision and environmental conditions. So we set about pushing the boundaries of what GRP pultruded profiles can achieve.

    Through years of rigorous testing and development, we’ve refined our processes to achieve superior manufacturing standards and intelligent design optimisation, setting us apart from the competition.

    The result?

    • Up to 50% stronger than other GRP profiles
    • Up to 50% lower embodied carbon
    • Fully recyclable at end of life

    Designers and engineers can achieve more with less – using smaller or fewer components without sacrificing performance.

    The impact?

    • Greater design flexibility
    • Lighter profiles that are easier to handle and install
    • Lower material costs without compromising strength
    • Best-in-class sustainability

    GRP profile that provides engineers with a high degree of design freedom.

    We carry a large stock holding of GRP profile, including standard Angle, Channel, Box and Tube sections, all of which are designed to meet or exceed the higher performance E23 grade requirement of the BS EN 13706 standard (which covers the specification of GRP pultruded profiles).

    If you’re looking for safety handrailing, we can provide two GRP Profile solutions – Fabrication Handrailing and Key Clamp Modular Handrailing. By seamlessly integrating either solution with our d² Dura Grating and Dura Profile components, a secure and durable working platform is ensured.

    Our d² composites are backed by data from over a million testing operations. Through rigorous in-house testing and advanced data modelling, we meticulously analyse the properties of all of our composites. When it comes to GRP Profiles, our products are evaluated against BS EN 13706 – the specification for Pultrusions.

    The d² difference

    Our d² composites benefit from superior manufacturing standards and intelligent design optimisation versus the competition, pushing the boundaries of what pultruded profiles can achieve. Our GRP Profile is part of our d² range of enhanced performance products.

    Safer.

    We push boundaries

    d² is up to 50% stiffer than the competition. Using d² you can choose sections at half the weight and bulk of others, reducing labour and boosting safety.

    Stronger.

    Unrivalled performance-to-weight ratio

    Our GRP Profile has up to 3x the load capacity of similar sized competitor pultrusions. The additional strength of d² enables wider scope of use.

    Greener.

    Delivering sustainable change

    Not only does our d² GRP Profile use up to 58% less carbon than similar products on the market, it’s also fully recyclable at end of use – an industry first!

    Proven.

    All the data you need, instantly

    d² products are backed by data from over a million testing operations for structures designed to their exact specifications. Unlike others we conduct full profile testing for load and deflecting and coupon testing for strength and modulus.

    Applications for GRP Profile

    Structural GRP Profiles

    Structural GRP Profiles

    d² Dura Profile heavy-duty beam sections are a revolutionary innovation in the industry. The superior strength-to-weight ratio allows for the use of smaller or fewer components without compromising performance. Angle, Channel, Beam, Box and Tube are stocked as standard with options for special order.

    • A logical and cost-effective alternative to carbon, steel, aluminium and wood.
    • Being up to 50% lighter than steel translates to an equivalent reduction in carbon footprint.
    • GRP Profiles can be cut to specific sizes by our fabrication team.

    GRP Profile FAQs

    d² Dura Profile is a comprehensive collection of structural profile sections made from high performance Glass Reinforced Polymer (GRP) commonly used in construction and engineering applications where a combination of strength, durability, and corrosion resistance is required.

    GRP profile beams are used as structural components in place of traditional materials like steel or wood. Exclusive to Dura Composites, our d2 Dura Profile beams are stronger, safer, and greener than other GRP profile solutions on the market, with proven performance.

    European Standard EN 13706 specifies the minimum requirements for the quality, tolerances, strength, stiffness and surface of structural profiles. The standard divides pultruded structural profiles into two classes – E23 and E17, with E23 having the most stringent requirements for quality. On average, d² Dura Profiles exceed the challenging E23 Grade by an impressive 50%, allowing designers to select profiles that are either twice as strong or a third smaller when compared to GRP competitors, adding effieicny and cost saving to a project. Not only this, but d² Dura Profile can also be half the weight of their steel counterparts too, making them easier to lift, transport and install.

    Being up to 50% lighter translates to an equivalent reduction in the carbon footprint of Dura Profiles, making our structural beams a sustainable choice for environmentally conscious projects. In the case of our GRP channel for example, the d² Dura Profile 203 Channel can be used in place of a 125x65x15 Steel Channel section, achieving a 37% carbon reduction. And what’s more, we’re the first GRP company in our industry to offer an end-of-life and waste GRP solution that doesn’t rely on landfill and incineration.

    Yes, there is. We have an Environmental Product Declaration (EPD) readily available for our pultruded d² Dura Profile. This document provides transparent and verified information about the environmental impact of our product throughout its lifecycle.
