Abstract:
A molten zinc plated steel sheet superior in plating bondability and provided with both strength and shapeability is provided and a method of producing this molten zinc plating steel sheet by a continuous zinc plating production system which enables production at a low cost without modification of the system or addition of steps is provided, said molten zinc plated steel sheet characterized by comprising, by wt %, a steel sheet including C: 0.05 to 0.40%, Si: 0.2 to 3.0%, and Mn: 0.1 to 2.5%, the balance comprised of Fe and unavoidable impurities, having on its surface a Zn plating layer containing Al: 0.01 to 1% and the balance of Zn and unavoidable impurities and containing inside the steel sheet within 2 μm from the interface of said plating layer and steel sheet oxide particles of at least one type of oxide selected from an Al oxide, Si oxide, Mn oxide, or complex oxide comprised of at least two of Al, Si, and Mn.
