Why Use FRP GRP Enclosures and Covers?

FRP (fiber GRP (glass reinforced plastic) is very strong, non-corrosive and requires minimal maintenance during its working life. Enclosures are guaranteed not to warp, bend or break after installation. A uniform moulded exterior allows for easy installation of bulkhead fittings.

All sumps are vacuum tested in one of our factories for tightness, ensuring against water ingress.

Our covers are designed with a watertight seal and are flush with grade level to prevent trip and fall injuries. Our ergonomically designed lifting handle provides safe removal and replacement of covers without risk of injury to the back and fingers.

When installed as a system, our tank sumps will provide maximum protection for your fuel lines while allowing easy secure access for fuel delivery, maintenance and inspection for
