Zero Spangle Galvanized Steel
What is Zero Spangle Galvanized Steel
Zero Spangle Galvanised Steel (Zero Spangle Galvanized Steel) is a steel sheet product that has been hot-dip galvanized. During the hot-dip galvanizing process, the steel sheet is immersed in a molten zinc solution, which forms a layer of zinc covering the surface of the steel sheet, forming a protective layer against corrosion and oxidation.
Sporadic galvanized steel sheets are characterized by the absence of a visible zinc grain structure on their surface and a much flatter surface without the typical grain size. This gives Sporadic Galvanised Steel Sheet a smoother appearance and makes it suitable for applications where appearance is important, such as automotive manufacturing, appliance manufacturing, and construction.
