Live Load
Individual members with an angle of 30º to the horizontal or less shall be designed to support a 1.5kN
vertical point load at mid span.
Towers shall be designed as Class "II" structures - exposure category "D" - topographic category (3) according to ANSI/TIA/EIA-222-G or equivalent by in BS 8100: Part 1: 1986; Figure 2.1. (Range between?(300 and 700) meters ) .
The serviceability check of the towers will be carried out in accordance with BS 8100 clause 3.3. Or equivalent by ANSI/TIA/EIA-222-G
The rotational displacement for any tower structure shall be limited to 0.5º measured at the highest dish level.

Steelwork
The plan shape of tower is square
For lattice towers all steelwork including angles, flats and round solid bars will be hot rolled Grade S275 or S355 to BS EN 10 025. Also steelwork circular hollow sections will be hot rolled S275 or S355 to BS EN 10 210.
Bolts will be hot dip galvanized in accordance with BS 7371: Part 6: 1998.

The work plats should distribution on height of tower each 10m, except the end work pleat should put on distance 3m from the top of tower.


Antenna supports
Each tower need the number of antenna supports as following:-
1- GSM antenna . . . . . . . . . . . . . . . . . . . . . . . 6 pieces
2- Microwave antenna . . . . . . . . . . . . . . . . . . 8 pieces

The concrete work should be designed by ACI-318M-05 requirements. Take care for following design
criteria:-
1- Concrete strength Fc/28days 21 MPa
2- Reinforcement strength Fy 280 MPa
3- The maximum bars size which use in design reinforcement concrete is 20mm. (Diameter of bar)

Megatro 65m Mobile Communication TowerFor this 65m four (three) legged mobile communication tower and accessories, Our MEGATRO performs in-house design activities by PLS software or other software. Our Engineering Department is boasting of highly qualified engineering who are conversant with international codes and standards. The work is carried out with extensive use of CAE/CAD via a large of computer network. The computer hardware & drafting software are liked to the CNC workshop equipment for downloading of information thereby eliminating error and saving valuable production time. 

After fabrication all poles are delivered to the galvanizing facility to be Hot Dip Galvanized. Poles are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.

Moreover, we offer cost effective range of development and installation service regarding as an additional installation service. These are further, designed for both government and civil communications and suitable for both far-off and short distance communications. For additional protection, we cover these with protective shield to prevent the radioactive fallouts.
