Guidance on typical corrosion steel rates in water and soil for design use is provided in the recently published NZS3404.1 Steel Structures Standard – Materials, Fabrication, and Construction (SNZ,2009). The design rates given are those to be used for long-term exposure, i.e. where the designer is calculating a required sacrificial thickness of steel in order to meet the specified design life. This article covers the background to the corrosion rates provided in NZS 3404.1.
