It depends a lot on the quality and thickness of the galvanization.  I had 
two ham friends help me
dig up one of the  back stays from the 1920's Radio Corporation of America 
radio relay station antenna here in Belfast.
(1920 patent date)   The back stay is now at the Belfast museum, in great 
shape - no rust.
I'm looking at 2-in x 2-in galvanized welded wire mesh as a ground
 screen alternative.    The question is, does anyone have experience with 
how
well something like this would hold up?
