The piles used to protect concrete deck or other water front structures from the abrasion or impact that may be caused from the ships or barges (when they are tied up at the desk), are called fender piles. The fender piles are originally made up to timber.

Sometimes a man-made marine structure is made that extends out from the water level, termed as dolphin is also used to protect structures from the possible impact by ships. These are constructed by driving piles in a line and are connected above water level.

Fender piles can be of wood, steel or concrete depending on the design criteria. In case of concrete piles the prestressing can also be used to increase the fending capacity.  Timber fender piles are less expensive initially than the steel fender piles and also require less long-term maintenance.
