Specification

Surface Finish of Galvanized Steel Coil

Surface finish	Pattern	Application
Regular Spangle	Standard spangles with flower pattern	General uses
Small Spangle	Minimized spangles than regular	General painting applications
Big Spangle	Big spangles than regular	General painting applications
Zero Spangle	Extremely minimized spangles	Special painting applications

Surface Treatment

Surface Treatment	Features
Chemical passivating treatment	minimize thechance of white rust forming during transit and storage
Chemical passivating treatment	maintain thebright, shiny appearance for a longer time
Oils	minimize thetendency for storage and transit stain
Passivating + oils	provide theprotection from storage and transit stain by special chemicals calledcorrosion inhibitors
