Steel tower being main supports for power transmission line project, it is often produced by angle steel, steel pipe or other small steel components. In general, it is divided into guyed tower and self-supporting tower. Gantry tower both have guyed or self-support types.
MEGATRO produces and designs every type of 400KV overhead line gantry steel tower or other truss& mast. MEGATRO provide the 400KV overhead line Gantry Steel Tower for our esteemed clients. The Tower Line work involves Survey, check survey, and span calculations essential for tower extensions. Moreover, Tower designs and prototype approval is done. In material choice, we consider high voltage and longer distance power transmission, and combine local climate condition, the steel material must be high tensile with strength, solid, wind resistance well.
Since 2004, MEGATRO focus mainly international market and had export many kind of transmission structures to overseas clients. MEGATRO has been manufacturing lattice transmission tower & tapered steel poles for lighting, traffic control, communication and utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software.
MEGATRO is one of the few manufactures who assemble a face of 400KV overhead line Gantry Steel Tower. 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 400KV overhead line Gantry Steel Tower 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' 400KV overhead line Gantry Steel Tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
