    Excellent bi-directional strength and stiffness.

    Our pultruded GRP Grating is an alternative to our moulded grating panels and has various structural shapes, ideal for areas with regular impact that require an extended drainage solution and wide span. All the variants utilise distinct bearing bar shapes and sizes, offering excellent bi-directional strength and stiffness. The selection depends on project-specific requirements, including load-bearing needs and overall aesthetics.

    Pultruded Flat Bar Beam

    Flat Bar Beam

    Provides a smooth, flat surface suitable for pedestrian areas and locations requiring enhanced drainage.

    Pultruded I Beam

    I Beam

    Features an I-shaped cross-section with flanges on both sides of a central web.

    Pultruded T Beam

    T Beam

    Exhibits a T-shaped cross-section with a central web and flanges extending beyond the web for added lateral stiffness.

    A consistent, high-quality pultrusion process.

    Dura Composites’ pultruded open safety flooring excels in areas with regular impact, offering extended drainage and wide spans. Its durability, lightweight nature, corrosion, and chemical resistance surpass traditional materials like steel. The pultrusion process ensures a consistent, high-quality product, featuring pultruded load bars connected by tie bars.

    • Ideal for Impact Areas: Suited for locations with regular impact, providing extended drainage solutions.
    • Superior to Steel: Outperforms steel in durability, lightweight design, and resistance to corrosion and chemicals.
    • Consistent Quality: The pultrusion process guarantees a consistently high-quality finished product.
    • Large Span Support: Ideal for applications requiring strength at larger spans compared to molded grating.
    • Versatile Applications: Suitable for industrial, chemical, nuclear, construction, and marine industries, including hazardous areas.

    Dura Grating in blue is a preferred choice for rail catchpit covers, aquaculture industries, and drainage walkway solutions in busy leisure centers. Pultruded components are also ideally suited as trench covers to vehicular loading requirements for infrastructure installs including power, telecoms and utility projects.
