Megatro Communication mast
MEGATRO provide every type of lattice steel tower & mast for communication. These masts are, typically, tall structures designed to support telecom accessories with antennas (also known as aerials) for telecommunications and broadcasting, including television, antenna and other supports, which also can accommodate a variety of disc with network parts. MEGATRO also offers a wide variety of accessories and mounts.
Our communication mast is 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.
Communication masts classification is based on a number of considerations, including structural action, which denotes how the tower is erected; cross section, which indicates the shape of the towers (either square, hexagonal, polygonal or triangular); type of material sections, which refers to a tower's angular or tubular bracings; and type of surface it is placed on. It has some type of cell phones tower, cellular tower, wireless tower, microwave towers,
