Meeting Your Project Buoyancy Needs
Ace Roto-Mold 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 UV inhibitors to prevent damage from the sun, debris, oil, gas, marine organisms, salt and fresh water. A nominal wall thickness of 0.150” and a
minimum thickness of 0.125”, 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 reserve buoyancy possible. The foam interior provides flotation if the outside shell becomes punctured and is continually tested to meet or exceed the 7-Day Hunt Water Absorption Test standard of 3 pounds 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.
ASTM D1998-06 Falling Dart Impact Test: Validates that virgin grade resin is being used and that the
molding process is complete and properly done. When punctured, Ace Roto-Mold Float Drums do not crack or shatter. (Other ASTM Standards that Ace Float Drums are in compliance with include: D1505, D1238, D1693, D638, D790B, D746, D648, D1621, D2863, D696, D3418, D1693A)
7-Day Hunt Water Absorption Test: Foam fill will aid in maintaining buoyancy if float becomes damaged. Properly steamed foam creates a tight seal which will prevent waterlogged floats and sinking docks. Void-free foam also supports outer shell walls, adding strength. Ace Roto Mold Float Drums meet or exceed the test standard of 3 pounds per cubic foot.
Encasement Wall Thickness Standard: Eliminates weak wall floats with early failure potential and reduces unnecessary repair costs. Ensures floats will hold up to pre- and post-install abuse. Ace Roto-Mold Float drums have a nominal wall thickness of 0.150” and a minimum thickness of 0.125”.
Tank Tested Buoyancy Ratings: Calibrated Tank Tested Buoyancy for each model unit is available.
US Army Corp of Engineers Regulation 33CFR Part 327.30:Ace Roto-Mold Float Drums meet or exceed the US Army Corp of Engineers standards under Regulation 33CFR Part 327.30.
15-Year Float Drum Warranty: Ace Roto-Mold offers a 15-Year Float Drum Warranty on all of its manufactured float drums to the original owner.
