Title:
PLATED STEEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/230716
Kind Code:
A1
Abstract:
This plated steel material is provided with: a steel material; a zinc-based electroplated layer formed on a surface of the steel material; and an organic resin coating layer formed on a surface of the zinc-based electroplated layer. The surface of the zinc-based electroplated layer has hairlines extending in a prescribed direction. The surface of the zinc-based electroplated layer has an Ra (ML) of 0.10 to 0.70 μm. In the surface of the zinc-based electroplated layer, a peak count PPI at a reference level of 10 μinch measured in a direction orthogonal to the hairlines with respect to Ra (MC) satisfies PPI ≥ 350 × Ra (MC). In a surface of the organic resin coating layer, Ra (CC) with respect to Ra (CL) satisfies Ra (CC)/Ra (CL) ≥ 1.10, and the Ra (CC) with respect to the Ra (MC) satisfies Ra (CC) < Ra (MC).
