Its use for parking is at best inappropiate, and at worst a waste of

The best material for parking is actually a tough hedge..
However, given what you have, I'd be inclined to use scaffolding poles

I'd suggest "bendy bollards" or for the post-industrial look, tractor

I remember seeing a barrier on an industrial estate made from 250mm x 250mm
I beams. Someone had still managed to bend it.
