Rust and corrosion are expensive for owners and taxpayers.  Deteriorating buildings, roads, bridges, etc. are costly to repair, and without sufficient corrosion protection, maintenance is done often, or in the worst cases, the structure must be rebuilt.  With the push toward sustainable development, specifying structures with longevity that require little maintenance over time provide both environmental and economic benefits.
