Leaning towards using expanded metal for my deck surface. Please excuse the crude drawing LoL. It is made of square tubing, I need to put supports in between the frame squares for lack of better words. Thought of using 1x1x1/8 angle or using sq tubing or using 1"x.125" flatbar turned on it's edge. Which would you recommend and would you run it like "A" or like "B" in the crude drawing.
