Historically, trench and manhole covers have been manufactured from metal or concrete, which environmental factors can cause to crack, crumble, corrode or fracture. Where high load ratings are required (like road crossings, ports, airports) covers can weigh hundreds of kilograms.

Fibrelite covers offer a light, strong (A15-F900), corrosion-free alternative for every access requirement, accredited to the ISO quality standard and our FL90 and FL76 covers are accredited to the British Standards Kitemark.

When replacing previously installed failing concrete and metal covers, Fibrelite’s technical and manufacturing teams can work with you to create a retrofit covering solution to fit directly into your existing frames to avoid costly and time-consuming breakouts of existing structures and curing time resetting structures into concrete. In critical high trafficked areas this is a major advantage.
