    FRP Trench Grating & Trench Covers

    trenchgrateinstallation

    Pultruded Fiberglass Reinforced Polymer (FRP) trench covers are custom designed specifically for your trench application. Our customers prefer the FRP grates over steel grates due to their lightweight and corrosion resistance features.

    Our FRP trench covers offer a high level of customization, allowing you to tailor the water ingress openings, flow rate, and hold-down requirements to your specific trench type and code requirements. The top surface features an integrated texture that meets ADA and OSHA slip requirements. You can also choose from a range of resin options, including our standard Pultex® polyester (1500), fire-retardant polyester (1525) and fire-retardant vinyl ester (1625).

    Advantages of Composite Trench Covers or Grating

    There are many advantages to choosing composite trench gratings over alternative trench cover systems, such as:

    • Uniform construction — The pultrusion process allows fiberglass covers to be fabricated with uniform consistency, which results in enhanced strength, sturdiness and load distribution. Due to their bidirectional load-bearing design, pultruded grating systems can also handle much higher loads than other grating materials
    • Impact, Corrosion and UV Resistance — Fiberglass grating provides excellent resistance to corrosion, UV light, impacts and environmental stresses. These qualities also make them easier to maintain and allow them to perform reliably for years, even in high-load applications and extreme environments
    • Improved Water Management — FRP is the preferred material for water management over steel due to its non-corrosive properties. Because FRP doesn't rust, the grating lasts longer and is better for the environment downstream
    • Reduced Weight — Fiberglass grating systems are significantly lighter in weight than their concrete and steel counterparts, making them more accessible and, consequently, less expensive to install. The use, installation and care of fiberglass trench gratings are more manageable than traditional materials due to their low weight and maintenance-free characteristics, which help reduce worker fatigue
