Plating property, plating adhesion and spot welding excellent in hot-dip galvanized steel sheet and a method of manufacturing the same

摘要

Relates to galvanized steel sheet, and by forming an alloy phase between the plating layer and the base material steel plate, it is possible to prevent the phenomenon that the plated layer is peeled off, the present invention only improves the coating adhesion and plating property and more and a method of manufacturing the same, and hot-dip galvanized steel sheet can be improved spot weldability not, increasing the life of the spot welding electrodes.
