Dock Floats & Tanks

Dock Floats & Air Tanks by Ace offers both rotationally molded and blow-molded designs. With over 70 different sizes available, from one to four feet wide, three to eight feet long, and eight to thirty-six inches high, you are sure to find an Ace float drum that fits your needs, whether you are a private dock builder or a contractor for a large marina complex.

Ace offers a 15-Year Float Drum Warranty on all of its manufactured float drums to the original owner.

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. 


8 Main Points to watch for when viewing this video
(Point #1 contributes to Point #6)

  1. Virgin grade materials - no regrind - best materials.
  2. 15-year warranty.
  3. The entire foaming process.
  4. Wall thickness testing.
  5. "Outer shell is properly cured so there are no air bubbles below the inside 1/3 of the wall thickness".
  6. The ASTM D1998-04 Falling Dart Impact Test - 90 ft. lb. (standard) - a hole in part without shattering is good - competitor coupon (sample piece) shattered at 90 ft. lb. and even 30 ft. lb. which means they probably are using "off-spec" material / or heavy amount of regrind/adding color to cover up regrind / or all of the above. This is very important to the durability of the float as you can see. This also illustrates why ACE has the best warranty in the industry.
  7. The Hunt 7 Day Water Absorption Test process.
  8. Tank testing process.
