Evaluating Strength Loss on Tubular Steel Poles Due to Corrosion

One key area to evaluate in a steel pole inspection is corrosion, which is a naturally occurring electrochemical conversion of a refined metal (steel) to its original, more chemically-stable form of various oxides, hydroxides, or sulfides. While this chemical reaction is typically a gradual degradation, it does lead to strength loss on the poles. This white paper provides a methodology to use when assessing the strength loss and effects of corrosion during a lighting pole inspection.
