That is what galvanizing does.
The zinc acts as a sacrificial metal to protect the underlying iron/steel
and thus acts as a sacrificial anode. In the event the underlying metal
becomes exposed, protection can continue as long as there is zinc close
enough to be electrically coupled. After all of the zinc in the immediate
area is consumed, localized corrosion of the base metal can occur.

Hi Tower Talkers,
It seems that sacrificial zinc is commonly used in boating to stop
corrosion. The sacrificial zinc corrodes and "saves" the metal to which it
is attached.
Does anyone in TowerTalk land have experience with using sacrificial zinc
with towers and/or antennas?
