Trenchlite® GRP Cable Troughs

Our Trenchlite® GRP cable troughs are lightweight, cost-effective solutions that still provides you with exceptional structural strength. 

Why the Fibex Trenchlite® GRP cable trough system over other composite and concrete alternatives?

Compared to precast concrete trenches, our Trenchlite® GRP cable troughs are 90% lighter.

As a result, our cable trough system is easy to install, reduces labour for workers and improves safety conditions.


Fibex GRP cable troughs have a reinforced design – they offer significant advantages over typical polymer, composite and concrete troughs and trenches.

For example, our cable troughs can meet 40-tonne load ratings without needing any concrete surround.

With all of these benefits, it is clear that Fibex fibreglass troughs are the ideal solutions for a wide range of applications and projects.
