What is a Spangle? - Definition from Corrosionpedia

A spangle is the visible aesthetic feature of crystallites on the surface of a galvanized steel sheet. The spangle appears as either a snowflake or a six-pointed star pattern. This is produced on the steel sheet when certain alloying elements are either added to the liquid zinc or available as impurities.
