Power Transmission Tower
Power transmission towers divide into two categories: Lattice and Monopol.
Lattice Tower:
These towers are latticed and are made by the help of laths. They are physically stronger and occupy more spaces. They are usually used in suburban areas. One of the advantages of these towers is the possibility of installation without using crane.

Monopole Towers:
These kind of towers are made of one single base (flanged or telescopic) and are installed on one base.
They are made out of steel sheets with round or polyhedral cross sections. They are used inside cities were the space is limited and where there is a need for structures that occupy the least space. It should mention that a Monopol tower for transmitting 400 kv with the height of 50m needs 4sqm space for installation, however a lattice tower with the same specification and usage needs 120sqm space.
Ehdas Gostar Nirouye Pars
Having heavy cutting and bending equipments, Ehdas Gostar Nirouye Pars has the ability to produce Monopol towers with the length of 14m and thickness of 15mm for each parts which are made of steel ST52. This ability leads to major changes in Monopol tower designing and the designer of such structures using the structures more than 6m height considering this ability which result in decreasing the construction amount of such towers.
