Description
The HDG Electrical Steel Tubular Pole was designed as customer's
request. For Distribution and Transmission Line use. And with Base
Plate use Anchor Bolts to Install. Sections with 2 and use flange
to connect each segment. The hot dip galvanized in accordance with
ASTM 123 and the zinc coating at least 86 microns.
But to design the practical poles for customers use, normally we
need customers to provide us some parameter, like as the followings
:
- Pole top design load
- Where is the position of the load, the distance from the top
- The wind Speed
- How will the wire distribute
- Pole type with Burial Type or Base Plate type
- The connections mode, use slip joint or flange
- and others can be furthermore discussed when needed.
Through the efforts of the company staff, the support and
cooperation from all over the world. The company's products have
been exported to the Philippines, Malaysia, Australia, America,
Africa, Latin America, Panama, Suriname, Costa Rica, Colombia,
Jordan, Nigeria, etc. We have good export experience and with 1
container export to World per day on average.
