PVC electrical conduit works pretty well.
I used 2 - 10' lengths of 1 1/8" dia(I think) PVC electrical conduit, to support a 10' wide awning over our cockpit and part of the cabin.
Cut the full lengths in half, drill a few holes in the cut ends(not the bell fitting ends). Run some 1/4" nylon 3 braid through the the(dry, no glue) assembled pipe and then holes on the ends.
Knotted tight, you can pull the two pieces apart to store(stretch of nylon) easily in a cockpit locker.
I fit the sockets together and lay one pole at the forward edge of the awning(tarp)-over the boom, and one about 2/3rds of the way aft. The awning is lashed to the PVC(reason for extra holes the conduit), and lines run down to either lifelines or toe rail(I use both)
We've been using the two poles for many years. They're a little flexible but keep the awning high off the deck with tie downs and light tension, even in a little wind. We added a ring in the middle for a halyard lift(you don't need that unless it's big).
The awning is simply hemmed sunbrella(last 1/3rd is tapered to fit inside mizzen rigging), grommets around the edge, with a slit with clips, to go around the backstay.
Mid day sun, it is wonderful and we rig it often here in the Northeast.
