All shenanigans and crazy talk aside, does a single 36"x18" glass top usually have or need a center support? I've personally never seen a standard 3ft tank with a center 'brace' on the top frame. Apparently they do exist.
48" tanks were brought up in this thread, which use 2 glass tops in factory form, thus the need for the center brace to support one end of the glass tops.
