Steel is the most important engineering alloy but lots of money is used far more than for any other material to protect it from corrosion. The most important corrosion problem to contend with in all quarters worldwide is rusting of structural steel works. Steel frames that are properly protected will last infinitely but the best protection practices are not always used, so unavoidably allowing large tonnages of steel to rust away every single day with attendant effects. A steel structural

... must therefore include reliable corrosion protection strategy that is strictly followed; otherwise an unpredictable failure or impaired service performance of the structure is prone to occur. This paper revisits the general approaches that have been in use to combat corrosion of steel in their relative pros, and cons. The assessment concludes that, the best steel corrosion prevention strategy for every characterized natural or comparable environment has to involve a practicable painting or organic coating system. The aim of the paper is to provide readily public-available information that can be consulted and used, and enable appreciation of need for more positive researches or rethinking in protection of steelworks.
