Fibrelite Composite Access Covers

The widest range of FRP GRP manhole covers, trench covers and
access covers – standard and custom made



Fibrelite’s extensive range of composite access covers can withstand the same heavy loads as traditional materials, at a fraction of the weight. This means you can safely remove all Fibrelite covers manually. Even at F900 load ratings.


Strong composite manhole covers

Fibrelite’s highly engineered GRP composite covers are operator friendly, inert, very durable and capable of withstanding harsh field conditions for many years, including corrosion, slow and heavy traffic and extreme temperatures in service (preventing freeze thaw and other hazards). Designed to be non-rocking.


Ergonomic and Safe Plastic Manhole Covers

All Fibrelite’s composite covers can withstand the same heavy loads as traditional materials, at a fraction of the weight. Fibrelite covers can easily manually removed, even at F900 load ratings. Fibrelite’s ergonomically-designed lifting aid also eliminates the risk of back injury and crushed fingers.


Fully customisable

Fibrelite’s technical and manufacturing teams work with you to create a solution for your needs, including installation assistance. Not only can Fibrelite produce an access cover to meet your exact requirements, but all sizes and types can also carry specific markings and be the colored coloured to your specifications.

The previously installed metal covers made access difficult, the adverse conditions of steam vaults had caused the locking mechanisms to fail. The covers would heat up due to the steam vaults below, creating a health and safety hazard and putting the students and maintenance staff at risk of burning themselves.
