MEGATRO offers 33KV 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 33KV 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, Q345B, S355JO, S355JR, ST37, ST52, BS 50B or other.
This type of pole often used in city power transmission grid, with little space, economic and lower cost. Now MEGATRO can produce distribution pole with some type as follow:
(1) Flange connection
(2) Slip joint
(2) Step type
(3) Stagger type
(4) Others
Pole foundation types have:
(1) Direct embedment
(2) Anchor bolt
(2) Based plate
(4) Vibratory steel caisson
MEGATRO 33KV Steel H-Frame structures systems can accommodate a variety of cross-arm and other accessories. After fabrication33KV Steel H-Frame structures are delivered to the galvanizing facility to be Hot DIP Galvanized. 33KV 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.
MEGATRO can optimize design, to set a compact, narrow base, the pole design not only advanced but practical, with an emphasis on economic rationality to ensure safe and reliable operation. Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications.
MEGATRO is one of the few manufactures who assemble a face of 33KV Steel H-Frame structures. 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. MEGATRO 33KV Steel H-Frame structures systems can accommodate a variety of cross-arm and other accessories. After fabrication 33KV Steel H-Frame 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 towers. Even we take secondary finish for client again, which as duplex surface treatment.
