I remember a friend had a Rohn HDBX-48 foot tower many years ago, and
he went to have it re-galvanized. ( I think that the bottom part of a
Hy-Gain Hy-Tower is the same kind of tower). Anyway, when he was done,
all he had was a pile of scrap metal. It turns out that the tower was
steel, but the rivets that held everything together were aluminum. And
when they dipped the tower sections in the HOT galvanizing metal, the
aluminum rivets melted, and the tower fell apart. You might want to
check this out before you send your tower off to be galvanized.|

truly free... the folks they hire to do this unpleasant tedious work
minimum wage or thereabouts). Most places will also pick up and
a nominal (few tens of $) fee (unless you're hundreds of miles away).
Galvanizers charge by the weight of what they are galvanizing (not the
of the zinc, or anything that would make sense...nope.. they just hang
widget from a scale and drop it into the tank...)
Expect to spend some time calling around.. there IS a difference
places, and they all have their specialties.. Some have a limited
tank, and can't dip something like a 40 foot I-beam, and others can.
By the way, the whole process is one of those "furnaces of hell" sort
things. Quite impressive if you've never seen a huge pit full of

Subject: [TowerTalk] Rusty tower
I am ready to start the project of restoring an old Hy Gain HyTower.
a number of surface rust spots on about 30% of the galvanized surface.
Anyone have experience in removing the rust and know a better way than
Steel brush. Any suggestions on what to paint it with all over once
is gone. Thanks for your help. Van W4GIW
