[TowerTalk] Hot Dip Galvanizing

[Dubovsky, George]

And there's a flux tank just before the zinc dip - forgot about that one.

The hot-dip galvanizing process starts with a degreasing tank, rinse, then acid dip to remove rust, mill scale, old galvanizing - and aluminum rivets! Next, another rinse, and then the molten zinc tank.

The acid process can handle light to moderate rust, but heavy rust should be mechanically removed first (sand-blasting, scraping, brushing). Paint is a no-no.

That might not be just a story.....
A local friend of mine had a tower re-galvanized and the rivets corroded.
In investigating this he discovered that the rivets are aluminum.
Not really believing him I checked my rivets with a magnet.....uhhh, guess
what?

What type of freestanding tower is it? I seem to remember a story about a
ham who sent an HBX tower to the galvanizer and when it hit the tank the
rivets all melted. Maybe just a good story, but something to think about.

I'm cleaning up an old 65' freestanding tower and would like to get the 
thing galvanized.   I live in central Ohio and have looked up a few places 
that advertise the service but haven't called any of them yet.  What price 
range should I be looking at and how clean does this have to be before they 
can process it?   Anyone have one to recommend in Ohio that they have used? 
I was putting off calling until I had some sort of idea of what was a good 
price and what was a rip-off. 

  

Thanks!
