Weathering steel, which contains copper, develops a natural iron-oxide (rust) patina that is stable once formed, exhibiting increased corrosion resistance compared to carbon steel. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements present. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the patina, or protective layer.
Weathering steel is often marketed as a no-maintenance steel to the bridge and highway market specifically. However, in the last several years, the limitations of weathering steel have stifled its use. The development of the rust patina is fragile, and requires a balanced wet-dry cycle and it does not perform well in damp areas or where vegetation comes in contact with the steel. Though the rustic look is sometimes favored by designers, the issues of rust runoff and staining of concrete bases of poles and bridge columns is unappealing and has limited the use of weathering steel.
