hi,
i was wondering about this a year or two ago. i do not use galvanized rods myself. i know they are cheaper but there is always a chance for some question about the acceptability of this type rod that i just stick with copper.
all the ones i have ever seen are the small 1/2" ones..i never use any type of 1/2" rods, 5/8 is the min for me..1/2" will bend too easy!
