That might be a good option.
Usually similar sources are military tent pole sections, some from steel, some aluminium and some wooden with steel tube connections.
Yes organic!
Unfortunately good quality lightweight aluminium is relatively new and expensive and the old lightweight solution was WOOD.
The standard army tent pole sections had been made from wood till round about 1980 with steel tube connection, later steel tubes or heavy aluminium.
I guess they had been in use in every army and you get them everywhere very cheap.
But unconnectet sections are tricky in use, if you are alone!
But modern aluminium like you know it from bicycles, tent poles, airplanes is worth the investment, even if you have usually the opinion, that surplus from the nineties is fine and cheap. The new aluminium poles are far lighter than old ones.
And ones more to make it understandable:
Even for a bike packer trekking poles are an option because they are relatively cheap, very strong, some pack down very compact, some exist in a tested tough construction made from CARBONE which is ultra ultra ultra light, Most have a loop what is nice to have to hang up something like socks, torch or food.
If I cut a hasel stick I add at first a loop to the handle for my socks.
THE TREKKING POLE, WHICH I NEVER WOULD USE IN NORMAL FLAT COUNTRY, CAN BE THE BETTER TENT POLE, EVEN FOR BIKERS!
IT IS IDIOTIC TO EXCLUDE THIS OPTION FROM THE BEGINNING.
THEY ARE TOUGH AND OFTEN CHEAP!
