  • What is Weathering? Definition from Corrosionpedia

    Weathering is an indicator of corrosion in metal surfaces. It is often identifiable by changes in colour, texture, strength and other physical properties. The term "weathering" may also refer to a type of high strength, low alloy steel (made in the 1930s), which is highly resistant to corrosion.Read More

  • Corrosion protection SteelConstructionfo

    The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. In the absence of either, corrosion does not occur. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately 6 times the volume of the original material consumed in the process Read More
