All our dock pieces are underpinned with top quality ACE Float Drums. Ace foam-filled float drums offer durable flotation for a variety of new or existing dock systems. The plastic exterior one-piece seamless shell design prevents leakage and separation caused by weak joints. The drum wall is made of tough virgin polyethylene with ultra violet inhibitors to prevent damage from the sun, debris, oil, gas, marine organisms, salt, and fresh water. A nominal wall thickness of .150 offers a stronger, more durable float. The top of the shell is flat with molded-in mounting slots for easy attachment to any dock frame.
The interior of the float drum is filled with expanded polystyrene (EPS) foam. The foam is steam pressured for a tight fit that provides the highest buoyancy possible. The foam interior provides floatation if the outside shell becomes punctured and is continually tested to meet or exceed the Hunt Water Absorption Test standard of 3 lbs per cubic foot. The “Falling Dart” test and ultrasonic wall thickness testing are part of Ace Roto-Mold’s quality procedures to ensure the durable, long life of our float drums.
All other sizes are by special order only.
