Abstract
(EN)
The present invention relates to a steel sheet plated with an Al alloy and a manufacturing method therefor and, more specifically, to a steel sheet plated with an Al alloy which can be preferably applied as a vehicle steel sheet and the like and a manufacturing method therefor. An embodiment of the present invention provides a steel sheet plated with Al alloy and a manufacturing method therefor, wherein the steel sheet comprises: a base steel plate; an Al alloy plating layer formed on at least one surface of the base steel plate; and a Zn-Al plating layer which is formed on the Al alloy plating layer and comprises, by weight%, 0.5-1.0% of Al and the balance of Zn and inevitable impurities, with a plating adhesion amount of 3-12 g/m 2.
