    I could not find any threads about that.

    I did the following maths.

    Area in mm^2 is 314.15mm^2 per bar (10^2xpie)

    = 0.486933474 square inches inches

    870 Nmm2 = 126,200psi

    Thanks for your replies - I think what I will do is go for a 12mm sheet then if need be weld some additional supports on. I will let you know how much it bends (if any!).

    I will also ask for...
