MEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered. 

MEGATRO is one of the few manufactures who assemble a face of Tri-tubular telecom tower. 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 Tri-tubular telecom towers 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. MEGATRO' Tri-tubular telecom tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
