Welcom to QINGDAO MEGATRO HOLDING CO.,LIMITED
MEGATRO offers 138KV Steel H-Frame structures that can be used for electric sub-transmission or transmission applications in a range of lengths and sizes. MEGATRO H-Frames weigh considerably a little heavier less than traditional wood structures and are easier to transport and install. Wood structures are susceptible to rot, insect attack and deterioration that require costly maintenance and replacement. MEGATRO 138KV steel H-frames are engineered with an extremely high strength-to-weight ratio. The poles can be quickly deployed with minimal hardware and labor, factory drilled to customer specifications or modified in the field, if required, using a carbide-tip bit. In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, GR65, Q235B, Q138B, S355JO, S355JR, ST37, ST52, BS 50B or other.
MEGATRO 138KV Steel H-Frame structures systems can accommodate a variety of cross-arm and other accessories. After fabrication138KV Steel H-Frame structures are delivered to the galvanizing facility to be Hot DIP Galvanized. 138KV Steel H-Frame structures are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free H-frame structure.
