From what I observe in my region posts in both municipal and private construction - mostly fence posts and lighting posts - are gradually replaced from enforced concrete to steel pipes.
Is it just my region or is there a fundamental reason to prefer steel pipes to enforced concrete? I mean steel corrodes if not maintained regularly and enforced concrete doesn't seem to change over time at all so enforced concrete seems more practical.
How do steel and enforced concrete posts compare? Why prefer steel posts?
