For this lattice wind tower and mast, 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 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.

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.
