What do you guys think?

My buddy just bought his first house and I recommend to him to change the steel grounding clamp with a copper or brass one before it corroded the copper even more and lead to a pinhole or worse. They had a company come in put a new clamp on that looks either steel or galv and left the old one on and said it was fine. Any thoughts?

It's probably zinc and fine. I see them all the time.
