A wind tower is a slightly cone-shaped metal tubular structure formed by bending steel plates of different thicknesses. The tower can have different heights depending on the installed impeller and the power of the turbine generator. Land wind power towers are usually small, so metal plates with a thickness between 40mm and 60mm are used; Offshore wind power towers are made by rolling steel plates with a thickness even exceeding 80mm using a rolling machine. In addition, the latter requires anchoring to the seafloor through various types of foundations, such as using triangular piles or single piles, which are also made of bent plates.
