Galvanized Steel Coil Surface Structure: Zero Spangle vs Big Spangle-application in home applicaces &buildings
During the production of hot-dip galvanized steel coils, the molten zinc forms a distinctive crystalline texture on the steel surface as it cools and solidifies—a phenomenon commonly referred to within the industry as “spangle.” Depending on the specific parameters of the cooling process, galvanized surfaces are primarily categorized into two core structural types: Zero Spangle […]
