This article identifies some preventable coating problems noticed on 7 year old coated steel structural elements. The steelwork is located a couple of kilometres from the sea within an Atmospheric Corrosivity Category (ACC) at the high end of D. The ACC was determined from Table 4.1 of AS/NZS 2312 (SNZ, 2004) and Section 4 of NZCCG (Clifton and El Sarraf, 2005).
