Permanent booms are robust and hard-wearing with flotation provided by foam filled PEHD demi-spheres (35cm) or rectangular (80cm) floats to provide flexibility in the boom and they have a simple to attach/remove system ensuring easy float maintenance for cleaning or repair. These booms are quick to set-up, easy to deploy and hard-wearing. All Permanent booms have a steel galvanized chain ballast protected by a flange and ASTM junctions with fast connectors.
