All Rolling Barge structures are engineered with 6061 t6 Aluminum for all of our floating dock parts. This includes our boat dock frames, and floating dock kit frames as well as gangways. When we started out we researched the different material options: such as steel, wood and of course aluminum. Although we sell floating dock plans that are constructed from wood, everything we actually manufacture whether it be a kit, barge or swim platform is constructed with aluminum.
There are numerous grades of aluminum. 6061 T6 is used in a variety of other commercial applications such as aircraft wings, bicycle frames and even scuba tanks. We concluded that aluminum is the superior material for floating dock construction because of it’s strength and lite weight.
One of the arguments to using aluminum versus steel is the fatigue factor. Watch the video below to see why this should not be a concern.
