A zinc or zinc alloy electroplated metal sheet comprises a metal sheet having, on at least one surface thereof, a composite zinc or zinc alloy plated coating formed by electroplating with zinc or a zinc alloy in a plating solution which contains at least one organic compound selected from the group consisting of alkynes, alkynols, amines and salts thereof, thio compounds, heterocyclic compounds, and aromatic carboxylic acids and salts thereof. The composite plated coating has a coating weight of 0.5-200 g/m.sup.2 and contains 0.001-10 wt % of co-deposited carbon. The electroplated metal sheet has improved post-painting corrosion resistance, press formability, and spot weldability.
