Made-to-measure composite trench covers
16 May 2019
Many UK power generation facilities are adopting made-to-measure composite trench covers, according to Fibrelite.
Electrical power generation facilities have large quantities of cabling running below the ground as a matter of course, which must be accessed regularly. Back in the 1960s when many of these facilities were built, heavy concrete and steel or cast-iron trench access covers were the only option available. While there were associated risks and often specialised equipment required to remove and replace them, they served their purpose.
Many sites now are upgrading to made-to-measure heavy-duty lightweight Fibrelite GRP composite covers, especially on road crossings where both a high load rating (often D400 40t) and frequent access is required.
Fibrelite’s highly engineered GRP material is significantly lighter than metal, yet just as strong, and the company says it is fast becoming recognised as an effective alternative to traditional steel and concrete. Fibrelite GRP covers are about one third of the weight and can be manually removed safely by one or two people.
