Light Weight – Zero Maintenance – Corrosion Resistant
FRP composite trench covers are just 25 percent of the weight of concrete covers and provide easy access to pier utilities. The cover’s fiberglass sandwich construction is based on Composite Advantage’s vehicle bridge deck technology and has been designed to handle concentrated loads from equipment and cranes. The panels are resistant to corrosion caused by chemicals, UV light and sea water.
In the above picture, the FRP cover is 3 ft. by 4 ft. x 6 inches thick and only weighs 170 lb.
