B340LAE+Z Cold Rolled Base Galvanized steel Factory direct supply with High Quality

(1) Spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with an obvious spangle shape.
(2) Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the smallest possible spangle coating.
(3) Spangle-free coating
The coating obtained by adjusting the chemical composition of the plating solution has no visible spangle morphology and a uniform surface.
(4) Zinc-iron alloy coating
The steel strip after passing through the galvanizing bath is heat treated to form an alloy layer of zinc and iron in the whole coating. The appearance of this coating is dark gray without metallic luster. A coating that can be painted directly without further treatment other than cleaning.
(5) Differential coating
For both sides of galvanized steel sheet, coatings with different zinc layer weights are required.
(6) Smooth skin pass
Skin-passing is a cold-rolling process performed on galvanized steel sheets with a small amount of deformation for one or more of the following purposes.
Improve the surface appearance of galvanized steel sheet or be suitable for decorative coating; make the finished product not see the phenomenon of slip line (Lydes line) or crease during processing to minimize temporarily, etc.
