Welcom to QINGDAO MEGATRO HOLDING CO.,LIMITED
MEGATRO fabricates every type of tubular lattice steel tower for power transmission line project. Our power transmission line tubular lattice steel towers are constructed of solid steel pipe, with legs and angle iron cross members & pipes. Tubular lattice tower can reach heights up to 200 meter. MEGATRO is one of the few manufactures who assemble a face of every tower section. 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. Our tubular lattice steel tower for power transmission power has three types, one is four-leg tower, one is three-leg tower, and another is monopole tower.
After fabrication all tubular lattice 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's tubular lattice steel tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
