摘要
The present invention provides for a zinc-based coated steel sheet having a zinc-based coating layer and a lubricant film, which is formed on the zinc-based coating layer, containing zinc phosphate particles in an amount of 50 wt. % or more, and having substantially no reaction layer formed by reaction between the zinc-based coating and the zinc phosphate particles, and a method for the manufacture thereof. The zinc-based coated steel sheet according to the present invention has an excellent anti-peeling property, excellent frictional property, even in the non-lubricated condition which occurs at areas where the press oil film is broken, and excellent anti-galling property.
