[TowerTalk] Re-galvanizing tower sections

[Dan Cisson]

Rohn 45 DOES NOT have plates at leg joints, ( unless specifically requested
that way maybe)
It typically (all i have ever seen) has 2 bolts to a leg, a 5/16, and a 3/8.
And I was telling my expierences having re-galvanized tower sections, and
it was Rohn 45.  The price then in the mid-90's was $20.16 per hundred
pounds,
being 70lbs per section, 100 feet was a little over $150.00......Dan

Dan's concern about the legs becoming clogged with zinc is a valid concern
but unlikely with Rohn 45 because the

all the mounting hardware with galvanized nuts, bolts, and washers (I don't

hardware, cold galvanized all dings and

period (3 visits to the site). They are in great shape and some of the
sturdiest I've ever climbed. Hope this helps.
