The Galvanic Series in Action_ Why Zinc Sacrifices Itself While Barrier Coatings Fail

The Galvanic Series in Action: Why Zinc Sacrifices Itself While Barrier Coatings Fail

Every structural engineer, corrosion specialist, and fabricator making coating decisions for long life steel structures eventually confronts the same fundamental question: why does a zinc coating continue to protect steel long after it has been scratched, cut, or damaged, when an apparently intact paint or epoxy barrier fails from the inside out? The answer lies in the galvanic series, one …

Calculating Deposition Efficiency: Reducing Material Waste in Zinc Arc Spraying

For any fabricator, EPC contractor, or galvanizing alternative shop running twin wire arc spray equipment, zinc wire is one of the largest recurring line items on a project budget. Yet a surprising number of metallizing operations never measure how much of that wire actually ends up as usable coating versus how much is lost as overspray, rebound, and oxidation fines. …
