Fibrelite’s UK technical team (based in Skipton) worked closely with engineers and contractors at the Doncaster facility to design and manufacture tailor-made covers which accommodate the service pipes to the exact specifications of the customer. Trench covers were made in two load ratings; D400 for areas outside of the facility and B125 for the inside.

Fibrelite covers have the best strength-to-weight ratio in the industry, which means they can support large machinery and vehicles carrying heavy loads while being light enough to be removed easily and safely by two people using specially designed lifting handles. 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.

Manufactured using a specialized specialised composite material, they will not corrode over time, unlike metal and concrete, meaning that they will not need to be replaced for many years.
