Modular covers for ducts used in spaces where easy access and high durability are requiredOur Fibrelite trench covers are manufactured using the most modern injection technology, thanks to which a perfect technical product with a homogeneous, composite structure is created. Fibrelite covers were created with the main objective to eliminate the safety and health problems associated with the use of traditional, heavy steel covers. The big advantage of them is their versatility. Almost all sizes, load and colors can be created. Composite covers have always been seen as a more expensive alternative to traditional steel products. However, with the use of advanced Fibrelite production technology, together with the design of A15 and B125 covers with simultaneous increase in metal prices, composite covers can compete directly with cast-iron covers. Covers can be used in various industries including power stations, sewage treatment plants, waterworks, ports, docks, public places such as stadiums, railway platforms, buildings etc. No other cover offers both high abrasion resistance and pressure resistance.ApplicationsCurrently available dimensions: Manhole cover plate length / width 1200 x 450 mm Manhole cover plate length / width 1400 x 450 mm Manhole cover plate length / width 1600 x 450 mmManhole cover plate length / width 600 x 450 mm Manhole cover plate length / width 800 x 450 mm Manhole cover plate length / width 1000 x 450 mmSpecial lengths are available on request!Why choose a Fibrelite trench cover?Light, Durable and StrongWith an unrivalled strength-to-weight ratio, lightweight Fibrelite trench covers are available in a range of load ratings (from 1.5 to 90 tonnes) to suit every application and every budget.
