Method for manufacturing plated steel having excellent processability and corrosion resistance

Abstract

Provided is a method of manufacturing a plated steel material having excellent workability and corrosion resistance according to an exemplary embodiment of the present disclosure and the method includes steps of immersing a base steel in a hot-dip alloy plating bath; and forming a hot-dip alloy-plated layer on the base steel by drawing the immersed base steel from the hot-dip alloy plating bath and performing a cooling process. A first average cooling rate in the cooling process varies depending on a difference between a first temperature that is a temperature of the hot-dip alloy plating bath and a second temperature that is a solidification start temperature of a MgZn2 phase constituting the hot-dip alloy-plated layer.
