A jetty is basically a structure that projects from the land into the water, to create a connection among both areas. Regarding harbour and port structures, jetties can usually be found where docks are given sloping sides. Jetties are generally carried across the slope, and vessels can berth in deep water, either along the jetty or at the end of it.

Structurally, jetties are usually built as a deck on piles: the structure is founded on individual vertical or battered steel piles driven into the soil, and topped by a deck built with steel or reinforced concrete.
Steel HP piles and spirally welded tubular piles are ideal for this application.
Alternatively, jetties can be executed as a double anchored sheet pile wall, or with circular cells.
