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. |
