Is there a slight bend in that? Not sure if this will work for you since it's a thick piece, but when I made mine out of sheet steel, I screwed it down onto an old speaker box so the bend line was at the edge, then used a block of wood and a hammer (wood to soften the blow) and gave it some good whacks to make a nice crease. Rubber mallet worked, too, but nicer with a block to make it smooth.
