Precast patio bar top

I want to precast a 4'x10' patio bar top with a 12" overhang on one side and end but not sure how thick to make the slab. I was thinking 2" might do but am afraid that it won't be thick enough for the size of top. But if I make it thicker the top might be to heavy to move. I have looked into GFRC products but I still would not know how thick to make it. I am open for suggestions.

2" is fine - we use carbon fiber grid placed exactly @ the vertical midpoint of the form & no closer than 1" to any edge,,, for better strength, we also use corbels under the finished top
