Fibrelite were contacted by a third-party company whose client had tasked them with obtaining a lightweight upgrade for their traditional heavy concrete infill trench covers.

The previously installed concrete trench access covers over an oxygen pipework trench at this hospital were causing a number of issues due to both their weight and deterioration.
Fibrelite are proud to say that we have formed strategic partnerships with a number of major manufacturers of precast and preformed troughs.
With an unrivalled strength-to-weight ratio, lightweight Fibrelite trench panels are available in a range of load ratings (from 1.5 to 90 tons) to suit every application and every budget. Easy-to-remove, safe and available in an almost limitless range of RAL colors , sizes and configurations, each cover is designed to deliver years of trouble-free service even in the harshest environments.
Although FRP composite panels are now increasingly preferred to the traditional metal or concrete options – not every composite panel performs to the highest standards year after year.
Fibrelite trench panels are a high-performance product created via resin transfer moulding (RTM) to create a durable, monolithic cover that is truly consistently dependable What’s more, each one has been individually engineered in our own manufacturing facilities.
Fibrelite has been at the forefront of composite quality and innovation since 1980 when we designed the world’s first FRP composite manhole cover for the retail petroleum industry. Our high-performance, lightweight, safe-to-lift composite covers – including the unique F900 load-rated trench cover – are now selected by specifiers, architects and engineers worldwide.
Designed as a fit-and-forget product, our FRP composite covers are maintenance-free, durable and very strong.

A prime reason for selecting a composite cover is for its inherent resistance to corrosion. This makes it an obvious choice where water, waste water or corrosive liquids are involved. Fibrelite covers are also ideal where underground infrastructure requires protection from external corrosive compounds, such as salt.

Independent wet and dry tests carried out by Devon CC Materials Laboratory showed that Fibrelite trench covers – even when wet – had anti-slip properties equivalent to a modern high grade road surface – far exceeding health and safety advisory limits.
The thermal gradient properties of a composite steam cover significantly reduces the heat transfer from a steam vault to the surface of the cover. Typically, the surface temperature of a composite cover is only slightly above ambient temperature, even when subjected to extremely hot temperatures on the underside.
In fact, Fibrelite’s high-quality steam covers maintain their cool-to-touch properties and ability to support vehicular loads, even when pushed to a test temperature of 400°F.
Fibrelite’s composite covers are available in almost any size, color, shape and configuration, providing a truly bespoke, made-to-measure solution for every project.
Fibrelite trench covers can be custom molded to be stepped, allowing them to be retrofitted into existing frames with shallow rebates while maintaining their structural integrity (independently tested).
This allows direct replacement of previously existing metal covers, or installation in existing precast or preformed concrete trenches. Stepping can also reduce manufacturing cost and weight.
As well as being lightweight – typically a third of the weight of an equivalent-size cover produced in metal or concrete, Fibrelite’s ergonomically-designed lifting aid also eliminates the risk of back injury and crushed fingers.
Potential electrostatic discharging can be eliminated by using our “fully conductive” covers. We use a metallised fibre within the moulding process to achieve electrical continuity across the entire surface of the cover – and exceed the surface resistivity requirements of PAS26.
While the standard calls out for a maximum value of 1 KΩ/cm²; Fibrelite covers actually achieve a value of 0.0144 KΩ/cm².

Fibrelite has held accreditation to the ISO quality standard (ISO 9001:2015) and British Standards Kitemark since 1998. This commitment to product excellence enables us to provide the most comprehensive range of high strength modular and custom-made trench covers, with the very best strength-to-weight ratio available in the market today.
Each product is fully supported with dimensional product drawings and installation instructions which you can access by following the links from each product page on this website, or by contacting us directly via + 1 919 209 2404, enquiries@fibrelite.com or contact form.
An 18” square, raised cover manufactured and supplied by Fibrelite was put through testing as specified in BS EN 124 after 14 years solid service on a high-traffic forecourt. The test report confirms the cover easily passed and it was notable that the orange color had not faded, indicating that weathering and UV have no or very little impact on the performance of the Fibrelite cover over a sustained period.
There is no risk of theft with a Fibrelite composite cover as composites have no resale value in the scrap market – so you won’t be left with a dangerous, uncovered hole in the ground.
