| It is single self-supporting pole, widely used in power transmission line or telecom project. Based on the number of segments, this monopole towers are classified as four slope tower, Three slope tower; Two slope tower; Single slope tower; Straight tower. | | | |
| In telecom project, four slope monopole towers is generally placed over roofs of high raised buildings, when number of antennae required is less or height of tower required is less than 9 m. In power transmission line project, four slope monopole towers is widely used in city grid corporation for 10KV, 35KV, 66KV, 69KV, 110KV, 115KV, 220KV power transmission line project. | | | |
