Guidance on typical corrosion steel rates in water and soil for design use is provided in the recently published NZS3404.
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.
