Features of Our Galvanized Steel Coils :
1) Hot Dip Galvanized Steel Coil/Sheet is manufactured to have a long durability, strong corrosion resistance and shiny surface.
2) Hot Dip Galvanized steel features excellent forming properties, paintability, weldability, and is suitable for fabrication by forming, pressing and bending.

Surface Treatment of Galvanized Steel  Coils :

Surface Treatment	Features
Chemical passivating treatment	minimize the chance of white rust froming during transit and strorage
	maintain the bright, shiny appearance for a longer time
Oils	minimize the tendency for storage and transit stain
Passivating oils	provide the protection from storage and transit stain by special chemcials called corrosion inhibitors

Surface Finish of Galvanized Steel  Coils :


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