ABSTRACT:
A Sn-based metal-coated steel strip excellent in appearance comprises a Ni-based metal (such as Ni, a Ni—Sn alloy, a Ni—Zn alloy, a Ni—Fe alloy and a Ni—Co alloy) preplating layer and a Sn-based metal (such as a Sn—Zn alloy) coating formed thereon, and is characterized in that a Ni emission intensity line and an Fe emission intensity line obtained by glow discharge spectroscopy of the surface of the coated steel strip satisfy a relationship of the formula: T1≧T2wherein T1is a sputtering time at the peak of a Ni emission intensity line, and T2is a sputtering time at the inflection point of an Fe emission intensity line, or a relationship of the formulas: T1≧T2, and 1≦T1/T2≦1.5
