I'm designing a simple shop clamp jig with 2x3 1/8 wall alum rec hollow tube which spans a 4ft span, evenly loaded. What steel profile would give comparable deflection #'s. (steel's really cheap these days)

I'm trying to find a formula to determine max deflection @ center of a simply supported beam, rectangular section, with 2 point loads located at non-center location.
