Spelter shakes, also known as zinc shakes, refer to a condition affecting galvanized steel. This article will explore some synonyms for this term. One alternative is "white rust", which occurs when zinc oxidizes and forms a white, powdery substance on the steel surface. Another synonym is "zinc corrosion", which is self-explanatory as it refers to the deterioration of zinc coatings. Additionally, "zinc oxide formation" can be used to describe this process, as the zinc coating interacts with oxygen and forms zinc oxide. It is essential to understand these synonyms to identify and address potential issues with galvanized steel structures.
