Or do you think the 1-3/4-inch minimum thickness refers to steel, either solid or grid?
No running board made of steel was ever that thick.

I don't know how thick (deep) they were -- the drawings only say "steel grating to
meet AAR requirements". Certainly I have seen steel grate walkways on modern tank cars
that appear to be at least that thick.
