First I wanna say hi everybody,(noob) I just bought my first home and will probably be an avid member. I am very crafty but never have had a home to make improvements to. Now onto my question.

My summer project is to build a good neighbor fence that will last. I live in the Pacific N.W. Wind and Water are problems, along with my property being next to a creek, the soil is wettttttt :boat:
I understand that concrete absorbs water like a sponge, so wooden fence posts are out. I also hear that if you chip the galvanized layer on steel posts, they can rust pretty quickly. I was wondering in anyone has ever tried using copper fence posts. Copper doesn't corrode or rust. But it is soft and expensive. However if I don't have to replace the fence posts for decades than it will be money well spent.
I think however an 8' piece of copper would have to be pretty think and insanely expensive in order for it not to bend in the wind. I saw this video(Down Below) that would keep the copper part of the fence in the ground(where the rot happens) and the wooden posts above ground.
My questions are could I get copper that would be thick enough for this project to work? Could I mount the copper inside Galvanized steel posts instead of drilling huge holes in wooden posts? If not, is there a machine I could rent to drill these holes in the wooden posts easily? And if I am going in the wrong direction, is there a more durable option I haven't thought about?

Thanks for taking the time.

Is the assumption you want a privacy fence rather than something to keep the dogs/kids in the back yard?

4" PVC drainage pipe. Bury 3- 4 feet. Cut off excess height. Add rebar. Fill with concrete.

You are correct that copper is soft and would be extremely expensive. I'm not exactly sure where you would even source it. Copper does oxidize (turns green) and you would likely get significant reaction with fasteners. The idea of using pvc piping instead of sonotubes sounds interesting. I would add having a good layer of gravel at the bottom for drainage. You might be able to get some advice from a ready-mix supplier about a mix or additive for wet locations. Assuming you don't get a major freeze/thaw cycle. As always, you may have to be guided by your local building dept.

A copper fence I bet the guys that break into empty houses to steal the copper tubing so they can scrap it won't even look at it.

Anything against a Vinyl post? A hollow vinyl fence post directly in cement would work fine, that's how most vinyl fences are done. Mine is like that, and I can climb on it.

Agree, why not go vinyl? I'd actually use 4x4 PT wood and sleeve it with the vinyl and bury in the concrete. Doesn't matter how wet, it will last for many many years

How old are you and do you want the posts to outlast you? By comparison, I had to replace pt 4x4 fence posts which were sunk into the ground and compacted only - no concrete. They were set on the earth, no extra gravel underneath. Definitely 20 plus yrs and probably more. The posts broke at the neck - I mean the area just at the surface, which remained wet longer but exposed to the air. Deeper parts were rotting but still "wood".
If you use regular steel posts, it will outlast you. I had to remove some steel plumbing pipes that were used as retaining rods for landscape lumbers. 40 plus yrs and still good enough. The rust also acted as anchors. I'm in NJ. If you use concrete anchors, form a slope around the neck and use osi quad caulk around the post-anchor joint. I think pt posts will last more than a reasonable time with this. There is also treated lumber that are rated for burial. The homedepot pt lumber is resistance above ground and not for ground contact.
I don't know about pvc. They haven't around long enough. I know about pvc outdoor chairs and they did not last - became brittle in less than 10.

Another option would be chain link, using the vinyl slats in the mesh and SS post.

I have used SS on terminal and gate post with out breaking the bank, but never considered going SS with all the line post. You would need to contact a fencing dealer other than big box stores.
This one I have had good luck with

They also have great tech support via phone. SomeONE will actually pick it up and talk to you.

Good luck with your project
