I couldn't disagree more. First, the coating is zinc not 'galvanize' which is a
process. Second, Julio mentioned using Rohn 45 which does not slip together
instead each leg has a welded
plate with 4 bolt holes and the tower sections stand one atop the other. Dan's
concern about the legs becoming clogged with zinc is a valid concern but
unlikely with Rohn 45 because the
legs are rather large in diameter. If Julio can find someone in his area with
the capability to recoat the tower sections I would suspect it will cost a
great deal of money. If the tower
sections are in good shape I would suggest leaving them alone but replace all
the mounting hardware with galvanized nuts, bolts, and washers (I don't recall
the spec right now but their is
one common to hardware suppliers). My club recently installed 100 ft. of used
Rohn 45 at approx. 3500 ft. near the Pacific Ocean. We replaced all hardware,
cold galvanized all dings and
marks during assembly, and torqued all hardware 3 times over a 6 week period (3
visits to the site). They are in great shape and some of the sturdiest I've
ever climbed. Hope this helps.
