Welcome Aaron!
There's something called "plumbers strap" which is basically a metal strap with regularly-spaced holes in it along the long dimension.
That's what I think of when I see your photo, but I'm pretty sure that's not it as your's looks "beefier" than any plumbers strap I've seen.
Plus, plumbers strap is usually a bright silver looking color, and easily bendable.
But the general idea could be the same for your find.
