On a recent project, complex pre-fabricated, hot-dipped galvanized panels exhibited thicknesses in the range required for the entire subsequent coating system. It was not practical or possible to accurately map the thickness of the galvanizing across all the various parts, and DFT gauges available only measure the entire non-ferrous coating, including the galvanizing. How should thickness-per-coat minimums and maximums be controlled and verified for subsequent coatings?
