Using the 1/12 B(H^3) formula for calculating the bending moment of inertia, it has no torsional rigidity. .00. For the variables, I used a 2" wide .25" thick solid steel. A flat piece of steel will twist, angle iron will twist less, and an "I" beam even less. Just FYI.
I'm sure yours will be fine... You will probably never have a problem.
All the best!!! Todd
