Fibrelite’s lightweight FRP GRP composite trench and manhole covers are fast usurping metal and concrete covers to become the standard for high-performance industries like military and defense defence where performance and safe manual handling are critical. Fibrelite covers are typically 65% lighter than traditional cast iron and reinforced concrete covers, eliminating the need for costly specialized specialised lifting equipment and the accompanying health and safety hazards, even up to 90 ton at D400, E600 and F900 load ratings. Independent wet and dry tests carried out by Devon CC Materials Laboratory showed that Fibrelite manhole and trench covers – even when wet – have anti-slip/skid properties far exceeding health and safety advisory limits.
