STEEL GANTRY STRUCTURE FOR POWER TRANSMISSION LINE
This photo refer to our steel gantry structure for power transmission line project, it is for 35KV overhead line project. This structure like gantry to cross railway and some building in city or rural grid project.This steel gantries are made of lattice angle steel, channel steel, square pipe or other parts, which connected by bolts or welding. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of every steel structure and offers design for our clients.
MEGATRO can optimized design and make transmission steel structure less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of every type steel structures, and offers a variety of designs to meet client specific. After fabrication all steel structures, 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
Our main design engineer from USA, can use PLS software to design every type steel tower based on structural calculations and geometrical frame drawings. To meet the expectation, we produce shop drawings, components list and full production documentation, and even complete 3D models that facilitate the elimination of all design and drawings errors generated on the drawings. Another advantage is our 3D design and loading & design report, and can optimized the design and save cost for our clients.
