I think you could make a similar wall out of corrugated metal plates and poles. Each plate block would be 1,000 hit points. You won't have that exact texture available.
There are some bandit blocks that are bigger than 1x1 that (IIRC) look similar. I don't recall how durable they are. Given that one of those blocks can be 2x3x1 with only one pool of hit points, I doubt it will be as durable as using the plate blocks.
Or am I overlooking something?
