Hello,

I hope this is the right forum for this question, it is my first time posting here. A friend of mine would like me to make a coffee table
(45" long x 26" wide x 10" high) where the top is as thin as possible.
I've only made furniture from wood, but I thought, why not make the
table top from steel?

So the question is, how thick would a 45" x 26" piece of steel have to be to be rigid enough for use as a table top? I guess rigid enough so that a 200 lb person could walk around on top without much deflection. The plan is to use 4 legs with a 4" cantilever, so the central span will be 37" x 18". I calculated that if the top were 1/8" thick, then it would weight about 40 pounds, which is about the limit of feasibility.

Thanks, Wayne
