Many sites are subsequently upgrading to made-to-measure heavy-duty lightweight Fibrelite GRP composite trench covers, especially on road crossings where both a high load rating (often D400 40 tonne) and frequent access is required.

With an unrivalled strength to weight ratio, Fibrelite’s highly engineered GRP composite material is significantly lighter than metal, yet just as strong, and is fast becoming recognised as an effective modern alternative to traditional steel and concrete. In fact, due to the lightweight properties of their composite material, Fibrelite GRP covers are approximately one third of the weight, and all can be safely manually removed by one or two people with their ergonomically designed lifting handles. Fibrelite’s highly engineered composite covers also have an inherent resistance to corrosion, requiring a minimum of maintenance while providing a long-term solution.
