In either an I beam or C section the caps(top and bottom) carry the majority of the load. Another good practice for drilled holes is that they should be twice the hole dia from the edge(2D) for bearing strength.
When I worked with heavy trucks we never drilled holes in the top or bottom of the frame, only in the web between.

I'm about to make a fence-post-style slinky carrier and am looking at different ways to attach.
