Plated steel

A plated steel comprising:

• a steel;
• a zinc based electroplated layer formed on a surface of the steel;
• and
• an organic resin coating layer formed on a surface of the zinc based electroplated layer,
• wherein the surface of the zinc based electroplated layer has hairline extending in a predetermined direction,
• on the surface of the zinc based electroplated layer, a surface roughness Ra (ML) measured in an extension direction of the hairline is 0.10 to 0.70 μm,
• on the surface of the zinc based electroplated layer, a peak number PPI measured in a direction orthogonal to the extension direction with a reference level of 10 μinch satisfies a relationship expressed by Formula (I) with respect to a surface roughness Ra (MC) measured in the direction orthogonal to the extension direction,
• on a surface of the organic resin coating layer, a surface roughness Ra (CC) measured in the direction orthogonal to the extension direction satisfies a relationship expressed by Formula (II) with respect to a surface roughness Ra (CL) measured in the extension direction, and
• the surface roughness Ra (CC) satisfies a relationship expressed by Formula (III) with respect to the surface roughness Ra (MC),
• PPI≥350×Ra(MC) (I)
• Ra(CC)/Ra(CL)≥1.10 (II)
• Ra(CC)<Ra(MC) (III),
• where, a unit of Ra(MC), Ra(CL) and Ra(CC) is μm.
