A transmission tower is a tall structure, usually a steel lattice tower, used to support an overhead power line. They are used in high-voltage AC and DC systems, and come in a wide variety of shapes and sizes. There are four major categories of transmission towers: suspension, terminal, tension, and transposition. Some transmission towers combine these basic functions. Transmission towers and their overhead power lines are often considered to be a form of visual pollution. Methods to reduce the visual effect include undergrounding.

Tension tower was located between every three or four suspension tower to pull the conductors which are re-tied in tension tower insulators.

MEGATRO fabricates every structure tension tower by solid steel legs and angle iron cross members & pipes.  Structures can reach heights up to 200 meter. MEGATRO is one of the few manufactures who assemble a face of every tower section.  This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality.  And it helps to reduce on-site construction cost due to mismatched assemblies.  

After fabrication all tension tower are delivered to the galvanizing facility to be Hot Dip Galvanized.  Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing.  These strict procedures insure years of maintenance free towers.
