I have a 26" channel balance that is I have matched with your part # S380-26. The number stamped on my channel is 2530 B.S.I.. Everything matches up with the S380-26 except the aluminum channel one I have has rolled edges. Does this make a difference?

Nope, you should be okay. Some manufacturers make the metal channel in slightly different styles, but they all work the same way.
