Lattice Steel Towers for telecommunication
Lattice steel towers are made up of many different steel structural components connected together with bolts or welded. Many different types of lattice steel towers exist. These towers are also called self-supporting towers or free-standing towers, due to their ability to support themselves. These towers are not always made of steel; They can also be made of aluminum or galvanized steel.
MEGATRO provide every type of lattice steel tower & mast for telecommunication. These tower are, typically, tall structures designed to support telecom accessories with antennas (also known as aerials) for telecommunications and broadcasting, including television, atenna and other supports, which also can accommodate a variety of disc with network parts. MEGATRO also offers a wide variety of accessories and mounts.
This type tower also 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.

MEGATRO provide lattice steel tower for telecom 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.
