Zinc steel coils, as a kind of anti-corrosion treated steel, are also widely used in daily life. After a careful search, we can find galvanized sheets ranging from tables and chairs to pavilions. Galvanized coil sheets are most widely used in the construction industry and light industry, accounting for about two-fifths of the total applications.
What are the zinc coatings?
(1)spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely to form a coating with obvious zinc flower morphology.
(2)Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the tiniest possible zinc flower coating.
(3)spangle-free
By adjusting the chemical composition of the plating solution, a coating with a uniform surface without visible spangles is obtained.
(4)zinc-iron alloy coating
The steel strip after passing through the galvanizing bath is heat treated so that the entire coating forms an alloy layer of zinc and iron. This coating has a dark gray appearance with no metallic luster and is easily powdered during the violent forming process. It is suitable for use in addition to general A coating that can be painted directly without further processing other than cleaning.
(5)Differential coating
For both sides of the galvanized steel sheet, coatings with different zinc layer weights are required.
(6)Skin pass
Finishing is a cold rolling process with slight deformation on galvanized steel sheets for one or more of the following purposes.
Improve the surface appearance of galvanized steel sheets or be suitable for decorative coatings; temporarily minimize the slip lines (Lüders lines) or creases produced during processing of finished products, etc.
What are the Benefits of Zinc Coatings?
Corrosion Resistance: The most beneficial trait of coated steel is its effectiveness in protecting against oxidation.
Efficiency: Zinc Coatings protect the base metal from corrosion and will sacrifice itself to save the underlying material.
