Types and Uses of Galvanized Sheet

Regular Spangle	Minimized (zero) Spangle	Extra-smooth	Galvannealed
The galvanized layer is cured in the normal way to produce spangles	Before the galvanized layer is solidified, spray with zinc powder or steam to control the crystallization of spangles or control the composition of the plating bath to obtain minimized spangles.	After galvanizing, it is tempered and rolled to create a smooth surface	After the zinc solution is taken out of the steel strip, it is treated in an alloying furnace to make the coating form a zinc-iron alloy layer.
Good adhesion, good weather resistance	The surface is slightly smooth, and the surface is even after painting.	The surface is slightly smooth, and the surface is even after painting.	The surface is smooth, and the surface is uniform and beautiful after painting.
