In telecommunication or broadcasting, cell mobile, or TV, RADAR application, some roof top tower often installed at top of building. However, in order to make them stable, some stay wired often used. These towers also called roof top guyed tower. Guyed tower &mast are low cost solutions for mounting antennas at a height for telecommunication, broadcasting, TV, RADAR or other application. Since these guy wires are tensioned and spread around the base of the main structure itself, then roof top guyed towers have special requirements for their construction.
MEGATRO roof top guyed tower are designed and developed to receives assistance from guy lines. These are especially used in telecom tower in form of either supporting aerials at the top or by using the whole structure as an antenna.
MEGATRO roof top guyed towers also fabricated by solid steel pipe or angel steel, 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 provide Roof Top Guyed Tower design with below requirements
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.
