Default Steel pipe for flag pole

I have one of those cheap aluminum flag poles because I don't want
to spend $1200 on a high dollar one. It uses 2" pipe sections and
works pretty well, but it will bend in high winds. I used black
iron pipe inside of it for several years and it worked pretty well,
but in our last storm with 70-80mph winds, it did bend and the black
pipe broke at the junction (2 10ft sticks). I'm looking for a
replacement for the internal pipe that would be stronger. Local
metal place recommended sch40 1-1/4" in a 20ft stick but I was
thinking maybe some sort of roll bar tubing or similar. I'm not that
familiar with the terminology or naming convention of the different
metals. I can do up to 1-3/4" inside the aluminum sections. What
would be a good choice for this?

Do any of the landowners in your community have water wells?

My flagpole is one 21' length of 1" galvanized steel well pipe. Seems to
be the standard length, our well has always had 21 foot sections,
replaced when they corrode and get pinholes with new 21 foot sections.

The well company we use will either haul the old pipe off, or leave it.
I'd give you one of mine, but looks like you might be one time zone too
far away.
