My company is in the process of ordering ground rods from a Chinese company. As I am attempting to write a set of spec's for this rod I am not finding anyone who tells what the steel rod is actually made of. The copper cladding and the thickness of the cladding is listed, but no where do I find anything more than "steel rod".
I am assuming it is Cold Drawn 1018, but it would be nice to know. Does anyone have any idea?
