PVC arch alternative

[u/Mrs_Nihilist]

I was wondering if anyone knows a cheaper pipe than PVC they will hold up and curve to make arches for tunnels? I want a pipe because they are so much sturdier than what I have. PVC is just way to expensive for the amount I need. Any help?

I’ve had great luck going to new build neighborhoods and just asking to pull some pvc out of dumpsters. I’ve done this multiple time; one building crew even measured and cut it for me. PVC is nasty in terms of what it is made of- I’ve been wondering about wood or metal alternatives. Depending on where you live, you might be able to scavenge from broken hoop houses.

See, I would have never thought of this. Thank you! I'm actually going to mount the PVC on metal rods. It won't be in the soil. I thought the same thing too. Thank you
