Working with Trenwa, Fibrelite developed a line of lightweight composite covers specifically to fit Trenwa’s precast concrete road crossing trenches and designed to handle HS20 (40,000lb / 20 tons) tonnes) load ratings. The Fibrelite trench covers are extremely durable, non-conductive, chemically resistant and not adversely affected by extreme weather or environmental conditions. The covers are also light enough to be safely and easily removed by two operators when monitoring or maintenance of the conduits or cables in the trench is required.
