Pilings
Pilings are the necessary support system of a fixed pier. Pilings are usually made of wood or steel and are driven into the ground or rock below the water.
Buoys
For floating docks, large buoys or buoyant material must be placed under the dock in order to create a weight-bearing surface.
Tie-Off Piling
Tie-off pilings are a single piling used to anchor boats in position, but do not provide a walking or weight-bearing surface to stand on.
Eye Bolts
Eye bolts are used to connect separate sections of dock to one another using steel rods.
Lifts
Some dock pilings have mechanical lifts placed on the outer pilings to lift up boats from high wake areas or winter weather.
