This has been a concern of mine, and if it were a problem it should show
up as rust on the tower where the friction of the grip would remove the
galvanizing. so far ive never seen it on any tower. most of the wear
should come from tower torque. someone mentioned in another post that
rohn quit offering torque arms several years ago since they produced
only a minimal increase in torque bearing capability, but brought them
back since hams requested them.
