Moreover, MEGATRO is fully equipped and qualified to carry out Design Engineering services which includes:
√ Overhead Transmission line steel tower & Telecom steel tower
   Basic Design and Analysis
√ Shop Erection Drawings
√ As-Built Drawings
 

MEGATRO performs in-house design activities specializing in electrical overhead transmission &telecom tower steel works, which include wind and earthquake loading, static analysis, stress analysis by finite element methods and fatigue. 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.
 
Besides, MEGATRO is one of the few manufactures who assemble a face of 110KV 1GGA4-JG4 SC tension steel monopole This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies. After fabrication all 110KV 1GGA4-JG4 SC tension steel monopoles 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. All finished suArfaces shall be level and free of tears, burrs, clots and impurities.
 
Except otherwise specified elsewhere in the specification, the surface treatment and corrosion protection for all metal parts shall be in conformity with the latest revision of the standards listed below:
ASTM A 123 zinc (hot-dipped galvanized) coating on iron and steel products
DIN 55928 Protective painting of steel structure instructions
DIN 55945 Painting materials-Notions
DIN 18353 Paint work-Buildings
DIN 18354 Surface protection work for steel
DIN 53210 Determination of rust degree
DIN 55151 Determination of adhesion
ISO4528/3 Determination of rust penetration
 
MEGATRO' 110KV 1GGA4-JG4 SC tension steel monopole systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
