Smoothing Galvanized Coil Steel Customized For Coil Coating Industry

Smoothing Galvanized Coil Steel Customized For Coil Coating Industry

Coil Coating Industry
Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer.

Product Description

Galvanized Coil Coating:

(1) Normal 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) Zinc-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

Heat treatment of the steel strip after passing through the galvanizing bath to form an alloy layer of zinc and iron throughout the coating. A coating that can be painted directly without further treatment other than cleaning.

(5) Differential thickness coating

For both sides of galvanized steel sheet, coatings with different zinc layer weights are required.

(6) Smoothing

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.
