Galvanized Steel Coil

※   Normal zinc-flower coating: zinc layer in the normal solidification process, zinc grains freely grow and form a coating with obvious zinc-flower morphology.

※   Small zinc coating: During the solidification process of the zinc layer, the zinc grains are artificially limited to form the smallest zinc coating as possible.

※   Zinc-free coating: obtained by adjusting the chemical composition of the plating solution, without visually visible zinc flower morphology, uniform surface coating.
