More Information
Summary:The present invention relates to a zinc-nickel-alloy-electroplated steel sheet comprising a base steel sheet, and a zinc-nickel-plated layer which is located on at least one surface of the base steel sheet and which has a hairline pattern formed thereon, wherein the surface roughness of the surface of the base steel sheet, which forms an interface with the zinc-nickel-plated layer, is 0.7-1.0 µm on the basis of the average roughness (Ra) of the center line. According to the present invention, provided are: a zinc-nickel-electroplated steel sheet, which has a beautiful surface appearance after hairline processing, has better price competitiveness than a conventional stainless steel or a vinyl-coated steel, and can ensure high productivity in a coil polishing line; and a manufacturing method therefor.
