Do anti-rust coatings make a real difference on metal buildings?

One thing I didn’t pay much attention to at first was surface protection, but the more owners talk about long-term upkeep, the more often coatings come up. I ran into a discussion where https://www.uspatriotsteel.com/blog/anti-rust-coatings-and-longevity-in-metal-buildings/ was mentioned while people were comparing corrosion resistance and maintenance expectations, and it changed how I thought about durability. What interested me was the idea that coatings are not just an extra feature, but part of how a building holds up over decades. Especially in damp or harsh climates, that seems worth factoring in early.
