In 1955, ductile iron pipe became the standard of
municipal water and sewer systems throughout the
nation. And McWane Inc., based in Birmingham,
Alabama since 1921, became one of leading
producers of ductile iron pipe for the water
infrastructure of cities across America. Highly
adept at manufacturing products for use below the
ground, McWane has now applied its knowledge
and experience to developing utility poles that
stand up to virtually all types of comparisons, as
well as the most demanding environmental and
economic conditions.
Pole Properties
Historically, FKEC had used three types of poles:
concrete, steel and wood. All three materials have
their advantages, but there’s a significant downside
to each, as well. Concrete has weight issues, steel
is corrosive, and wood’s durability is a weakness in
the Keys environment.
Because of FKEC’s wind loading strength
requirements, wood poles have to be huge and all
the more heavy to do the job. The fact that wood is
treated with toxic preservatives is also a concern in
environmentally sensitive communities such as the
Keys. And, in spite of being treated, wood poles do
still rot.
As for concrete, in addition to the weight issue
(making transportation and installation both
difficult and expensive), those poles have
peculiarities in their design that make them prone
to cracking. Once water and salt get into the pole,
the rebar rusts and the concrete breaks away. That
destroys the pole. Concrete is generally thought
to be long lasting, and it is. But once it’s flexed, it
cracks; and that affects the life cycle.
Ductile iron poles are engineered and
manufactured to solve those problems and then
some. Ductile iron poles offer many beneficial
features:
These ductile iron poles are coated with PermaSafe
ceramic epoxy — interior and exterior — from a
minimum of 1 ft above groundline to the base of the
pole.
•
Environmentally friendly, made from recycled
material, and the poles themselves are 100%
recyclable
•
Combine the physical strength of steel with the
corrosion resistance of cast iron
•
Weigh about 50% less than comparable wood
poles — and far less than concrete
•
Manufactured by centrifugal casting for
consistent dimensional control and are
engineered for consistent strength with a
minimum yield strength of 42 ksi
•
Cost effective versus steel and concrete
