Title:
SURFACE-TREATED ZINC-COATED STEEL SHEET AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/074298
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a surface-treated zinc-coated steel sheet that is much less likely to be susceptible to white rust and has sufficiently high anti-glare properties. The present invention relates to a surface-treated zinc-coated steel sheet in which at least a steel sheet, a zinc-coating layer, and an organic resin coating are arranged in this order. In this surface-treated zinc-coated steel sheet, the organic resin coating has a thickness of not less than 0.1 µm, and the number (ppi) of protruding peaks with a height of not less than 0.1 µm from the mean line of a roughness curve of the surface of the organic resin coating measured at a cut-off value of 0.08 mm is not less than 300 per 25.4 mm of length in the direction of the mean line of the roughness curve.
