Custom molded moulded Stepped Covers
Fibrelite trench covers can be custom molded moulded 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.

Fibrelite Precast Partnerships


In 2014, Fibrelite and precast concrete trench manufacturer Trenwa formed a strategic partnership to create joint product offerings: Trenwa’s heavy-duty precast concrete road crossing trenches topped with Fibrelite’s traffic rated composite trench covers.
Since 2014 when the partnership began, Trenwa has sold well over a hundred of their precast trench systems with Fibrelite trench covers, now installed in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
As increasing numbers of people learn about the benefits of using Fibrelite trench covers, many are looking to upgrade previously installed concrete or steel trench covers. To meet this demand, Trenwa have worked with Fibrelite to design and manufacture custom moulded composite trench covers to fit Trenwa’s existing line of precast multi-duty trench systems.
