I'm chuckling thinking of the logic behind this. They want only the last three inches threaded presumably because it weakens the rod (determined from that old school where the rod was site threaded and threading too much was a waste of time and not a strength issue). They want galvanized or cadmium rod presumably for corrosion protection. But now the suspected weakest part has had the plating cut through so not only is it weaker than the rest of the rod but also sans protection. And somehow this is better than ATR plated or dipped after threading. I wonder if someone will pull cold galving it after the fact. Or tar.
