Product Features：
1. Hot-dip galvanized steel coils are characterized by the self-sacrificing properties of zinc and therefore excel in terms of corrosion resistance and processability.
2. As a professional manufacturer of galvanized steel coils, it is possible to produce the required amount of galvanization according to the customer's choice, and in particular, thicker galvanized layers (up to 120 g/m2) can be achieved.
Galvanized Layer：
(1)Normal zinc flower spangle coating
Zinc layer in the normal solidification process, the zinc grain free to grow up the formation of zinc flower with obvious morphology of the coating.
(2)Small zinc flower minimized spangle coating
Zinc layer in the solidification process, zinc grain is artificially limited, the formation of the smallest possible zinc flower coating.
(3)Zinc spangle-free coating
By adjusting the chemical composition of the plating solution obtained, does not have a visually visible zinc flower morphology, surface uniformity of the coating.
(4)Zinc-iron alloy coating
Through the galvanizing bath after the steel strip heat treatment, so that the entire coating generated by the zinc and iron alloy layer, the appearance of this coating is dark gray, no metal luster, in the process of intense molding easy to chalk, suitable for in addition to general cleaning, without further processing can be directly painted coating.
(5) differential coating differential coating
On both sides of the galvanized steel sheet, requires a different weight of zinc layer coating.
(6) Light finishing skin pass
Light finishing is for one or more of the following purposes, and a small amount of deformation of the galvanized steel cold rolling process.
