Fibrelite’s range of covers offer easy access for operators at this Natural Gas processing site. Due to the nature of what is underground the covers need to be easy access for operators who regularly check and monitor the valves and pipework. For operators working at the plant security and manual handling are critical issues when gaining access.

A number of the chambers required covers to be profiled in order to fit around pipework. This is an area of expertise that the Fibrelite site team can offer for bespoke applications. Fibrelite worked closely with both the client and contractor to ensure an extremely tight deadline was met.

Fibrelite’s access covers are lightweight, durable and very strong. Every Fibrelite cover is manufactured using high technology Resin Transfer Moulded production methods to create a highly engineered, monolithic composite product.

Damaged Cast Iron and Concrete Covers Replaced

The previously installed, heavy and damaged cast iron and concrete covers caused a health and safety issue and needed replacing. Fibrelite’s lightweight heavy duty composite trench cover was identified as the solution. Designed as a ‘fit and forget’ product, the maintenance free covers provide easy and safe access to the gas pipework and valves.

Sophisticated Highly Specialised Material

Fibrelite is the world leading manufacturer of glass reinforced plastic (GRP) composite manhole covers and trench covers. This sophisticated and highly specialised material is fast becoming recognised as the more effective modern alternative to traditional materials such as heavy steel and concrete.

Benefits over the more traditional, technologically inferior metal covers:
  • Lightweight for easy and safe manual removal
  • Load ratings from A15 to F900 (BS EN 124)
  • Chemically inert and corrosion resistant
  • Anti-slip / skid properties
Highly Effective in Preventing Water Ingress

Fibrelite’s sealed covers have proved highly effective in preventing water ingress and subsequent damage to essential valve equipment.
