Rods

Ron asked:

<<
 The H Beam
rod design is supposed to be superior in limiting rod stretch per weight
of the (steel) rod. (Or is that marketing hype.?)

It's less than accurate.
For a given material the parameter that affects stretch (for given load) is
the X-sectional area.  So if different designs have the same area (weight)
then stretch will be be the same regardless of shape.
