How does schedule 40 compare with HSS pipe structurally? same basic
alloys
and production?

Sorry, I'm not familiar with the term HSS where pipe is concerned----care
to
elaborate?

HSS = hollow structural steel. schedule 40 actually doesnt seem any cheaper
by weight,
I can get 1/8" sidewall HSS for about half the price. I guess theres no free
lunch any
way you dice it!



I fully agree with the idea of filling the pipe with concrete, but I'd
also
cap it when finished, well enough to prevent water from entering. If
you
could keep it dry inside, you'd have no rusting except from the
outside
in,
and that would take a long time to destroy the pipe----perhaps not in
your
lifetime. If you could tolerate the looks of galvanized pipe, even
that
wouldn't be an issue.

The pipe will be covered with wood to provide a clean look.

That could still let in some water. I'd be careful to preclude any water
entering the top, which will certainly not be to your advantage. You
could
do something as simple as cover the top with black visqueen, draping it
over
the sides, before covering it with wood. Anything to prevent water from
entering the top.

Agreed. There will probably be a little 'hat' at the top or something. Even
a plastic endcap
would be sufficient.
