Radio masts and towers are, typically, tall structures designed to support antennas (also known as aerials) for telecommunications and broadcasting, including television. They are among the tallest man-made structures. Similar structures include electricity pylons and towers for wind turbines.
Radio masts and towers also belong to telecom tower, which mailed used for broadcasting and television network system. MEGATRO can provide every type of radio mast and towers with different type and technical requirements. Radio masts and towers systems can accommodate a variety of disc with network parts. MEGATRO also offers a wide variety of accessories and mounts.
MEGATRO Radio masts and 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.

Design Requirements and Basic of Design MEGATRO TOWERS will guarantee the overall safety of the tower. MEGATRO TOWERS will submit design calculation report for member design of tower and overall structural stability of the structure, which is signed by a charted structural Engineer.
MEGATRO will supply the skeleton to scale, showing the assembly of the structures, the antenna mounting levels, other detail drawings etc.
The calculation method to be adopted for tower design will be decided by MEGATRO TOWERS with the consent of the client.
All materials will comply with British Standard (hereinafter called BS), Japanese Industrial Standard (hereinafter called JIS) or equivalent standards. The permissible stress of the materials will comply with BS, standard by Architectural Institute of Japan (hereinafter call AIJ) or equivalent. The standards adopted for all materials will be stated separately.
General Design Criteria
Mast will be designed based on GB, BS 8100, TIA/EIA-222-G-2006, IS 802 & IS875 or equivalent international standards.
The wind loading on the tower and antennas mounted on it will withstand a ground level wind velocity of 140 Km/h and survival speed of 180 Km/h including with height in accordance with latest BSI CP3: Chapter V: Part 2: British Standard (BS)
Antenna that will be considered when it calculates wind areas will be Six GSM antennas, Two each 600 mm diameter microwave dishes & one 1.2m Ø Microwave plus all the feeders for GSM and MW antennas.
Allowance will be given to the effective windage area of the following:
Feeder runway
Feeders
Platforms and guard rails
Ladder and ladder guards
MEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered.
