Summary for galvanized coating thickness Discussion
Galvanized coating thickness on steel rod is not usually designated the same way as sheet steel grades like G60 or G90, according to the thread. Joe Salerno asked whether rod can be obtained with a coating equal to G90. Dr. Thomas H. Cook replied that coating thickness on rod varies with the galvanizing method, the steel type, and the zinc bath chemistry. He added that with an air blow ring process, similar to tube galvanizing, one might expect about 2 to 8 mils of coating thickness, and noted that mils can be converted to microns by multiplying by 25.4. The discussion suggests that a direct sheet-steel-style designation is not a reliable way to specify rod coating thickness.
Q. I am trying to locate any information that will indicate the galvanized coating thickness for steel rod. Will it have the same designation as sheet steel (example G60, G90). Can steel rod be obtained with a coating thickness equal to G90?

A. Sir:
Coating thickness on rod varies by method, steel type, and zinc bath chemistry. Using air blow ring (like tube galvanizing, one could expect 2 to 8 mils) (multiply mils by 25.4 to get microns).
