Custom Moulded Stepped Covers

Fibrelite trench covers can be custom 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.

Stepped covers can be retrofitted to existing frames. Port of Felixstowe pictured (F900 load rated)

Stepped covers can be designed to fit precast and preformed trenches and troughs.
