I'd like to put a corrugated metal up from my floor several feet, and then transition into 1/2" OSB. I'm trying to figure out the best way to trim the transition. Should I put a J-channel inbetween or I was thinking of cutting a rabbet joint in a piece of wood trim to cover the top of the metal? Or is there a better way? What do I put on the floor where the metal touches, J channel?
