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.
