GRP Heavy Duty Engineered Trough Covers

The Fibex GRP Heavy Duty Engineered Trough Covers are considerably lighter than concrete, saving installation time, transport costs and labour.

Our GRP D400 Trough Covers are available in a range of lengths (300mm to 1000mm) and widths (600mm to 1800mm).

They load up to 40 tonnes making them ideal in areas where there is heavy traffic, such as carriageways, hard shoulders and bus depots.

All of our GRP Heavy Duty Engineered Trough Covers have been independently tested and certified to BS EN124 loading classification.

Our Heavy Duty Covers can be fitted in the Fibex GRP Cable Troughs, a pre-laid concrete rebate or steel angle frame. They can be supplied with the Fibex lifting handles for easy installation and removal.

Fibex Lifting Handles are available in several types: ‘I Type’, ‘Hook Type’, and ‘T Type’.

  • Two countersunk bolt holes which are compatible with M12 bolts for a secure fit
