In another place I hang out, we're discussing a tower that was
toppled by a tornado 25 years ago. Seeing as how this was a
327 ft tower, weighing ~135 tons, that's a lot of bent steel.

But the story is, it was not sellable as scrap because it was
galvanized. They ended up burying it on-site!

You guys know lots more about steel than I do, so why is it you
can't reuse galvanized steel?

It may have been related to the fact that welding/flame cutting galvanized
steel apparently releases very toxic gaseous compounds of zinc, so scrappers
may have been reluctant to cut it up -- altho one doesn't normally think of
scrappers as being a health-conscious environmental lot.... LOL
.. May have turned into a kind of scrap urban lore, in some locales. Just
guessing....
