Steel and Aluminum Towers

Towers are used to support transmission lines, radio and television antennas, radar and microwave equipment, tanks, bridges, etc. freestanding towers (such as transmission towers and some radio and television towers) are usually rectangular in plan.

The tall towers used in the electronic industry are usually guyed. The plan is usually an equilateral triangle, with the legs at the vertices. Most steel-tower members are hot dipped galvanized for weather protection.

Steel Transmission Line Tower

Aluminum Tower
Aluminum towers are usually made of alloy 6061-T6, which is corrosion- resistant in all climates without surface protection. It can be extruded to produce optimum shapes for resisting stress and simplifying joints. Because of their lighter weight, aluminum towers can be flown by helicopter to relatively inaccessible sites.
