MEGATRO roof top tower also belong to telecom tower, which designed to support telecom accessories with antennas for telecommunications and broadcasting, including television. But this tower is located in roof of every construction building.
Roof top towers also fabricated by solid steel pipe with angle or bracing members, which provides great strength, low weight and wind resistance, and economy in the use of materials, lattices of triangular cross-section are most common, and square lattices are also widely used.
After fabrication all 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's roof top tower systems can accommodate a variety of disc with network parts. MEGATRO also offers a wide variety of accessories and mounts.
