Masts are structures that are constructed as a basis for installing various types of antennas for receiving and sending electromagnetic waves.
Often, to lighten the tower and reduce its windbreak level, the tower is made of metal and lattice. At the same time,
sometimes metal telecommunication towers with solid and non-lattice surfaces are implemented.
Sometimes they are made using reinforced concrete with full surfaces. In these cases, the towers are used only as a base for installing the antenna, but by creating uses such as restaurants, city views, game city conference center and the like in different parts of the tower, make it an attractive center. They become tourist and recreational. Metal lattice towers are one of the special and important types of structures in structural engineering.
Lattice towers are divided into two types of self-Supporting towers and Roof Top towers.
