2. Coating Processes and Surface Treatments The

Minimized spangle zinc-coated steel sheet in which the grain pattern is visible to the unaided eye, and is typically smaller and less distinct than the pattern visible on regular spangle. The zinc crystal growth is arrested by special production techniques, or is inhibited by a China Prime Calamine SGCC Regular Spangle Gi Galvanized Prime Calamine SGCC Regular Spangle Gi Galvanized Metal Iron Steel Coils. Galvanized coil, the thin steel plate immersed in the molten zinc bath, so that its surface adheres to a layer of zinc thin steel plate. At present, continuous galvanizing process is mainly used to produce galvanized steel sheet, which is made by continuously immersing coiled steel sheet in galvanized bath and alloying galvanized steel
