Power Transmission & distribution line

Our Power Transmission line Lattice tower can be made out of steel profiles that are put together to form a lattice. Our lattice tower is very strong and we manufacture them with complicated technology. The towers are formulated to house a variety of accessories which include platforms, ladder ear, step bolts, safety cage and so on. Our latticed tower can be used in these fields such as electric power transmission line tower, telecommunication tower, broadcasting tower, watching tower, microwave tower, mapping tower, communication tower, crossing-river tower and other applications.
