MEGATRO fabricates every structure
from the ground up. Our angular steel towers are constructed of solid
steel legs and angle iron cross members & pipes. Structures 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.
After fabrication all towers
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 angular tower systems can
accommodate a variety of cross-arm. MEGATRO also offers a wide variety ofaccessories and mounts.
