Anti-Slip Duct, Gully and Trench Covers
At GripClad, we offer GRP trench, duct and gully covers to cover gaps where ease of access and structural performance are critical. Our GRP covers can be installed for a new build, or to replace ageing concrete or wood covers over gullies and ducts with concrete or metal recesses, make them a versatile solution.
Our lightweight GRP Grating covers are available with solid tops, or open mesh grating, depending on your requirements and application.
GRP covers from GripClad are suitable for all industries including power, utilities, water treatment, ports, rail, retail spaces, public works areas and substations. The unique properties of GRP provide strength, lightness, slip and trip resistance and superior resistance to the elements.
The versatility of our GRP trench covers makes them ideal for both indoor and outdoor applications. They serve equally well as cable duct covers indoors as they do as replacements for pipe gully covers outdoors.

Our GRP solid top or open mesh grating covers are easy to lift, transport and install, unlike bulky concrete cover slabs. Their lightweight and easy-clean design make them very low maintenance. Since they are resistant to weather erosion and chemical corrosion, you can enjoy a GRP grating for its entire 25-year life.
