Electrical Metallic Tubing - electrical conduit - some is now grey coloured PVC. It's used in the building trade to protect electrical wires from weather, abrasion, or critters chewing on it.
Question: What is EMT?
I'd agree that for that sort of size and shape, 3/4 inch is plenty, but it looks as if William's using plastic snow fencing sort of stuff. The first lot of "modular fencing" we built was done with plastic fencing. We recently bought some similar looking stuff which is supposed to be used as a layer for stabilizing roads which is supposed to be much stronger but even then, I wouldn't trust it near the ground as I suspect critters would chew through it. If you want to only build this once more, I'd at least consider the lower areas being something like hardware cloth. Yes, it will cost more, but I wasted a *huge* amount of time last spring trying to resurrect that modular fencing as I needed it desperately. Between solar degradation, animal holes, or unknown trauma, I'd have been much further ahead to change the system, but wasn't given that option. We've also used this fine, black mesh that's sold as "deer fencing" and it's not coped with critters near the bottom and hasn't stood the test of time in the ways we've used it. I'm in a similar situation with long lengths needing protection, rather than a simple large area that can be protected all together and farmed inside of. I've got bits of fencing all over trying to use my limited sun to grow things that deer would like to harvest for me.

That is exactly the type of idea I was thinking about.
So a mere 3/4” is good enough? That’s great.

My thought was the hardware cloth on one side, bug mesh on the other held onto one inch PVC with clips of some sort.
