STEEL PLATE FOR DOOR FRAME OF VEHICLE, APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a deviation plating steel plate for an automobile door frame to ensure corrosion resistance, to improve prevention and weldability plating peeling, and improve image clarity and formability, a manufacturing apparatus thereof, and a manufacturing method. The provided deviation plating steel plate for an automobile door frame is formed with a first zinc plated layer of a rear film on one surface of the steel plate requiring the corrosion resistance and a second zinc plated layer of a thin film on the other surface of the steel plate requiring relatively less corrosion resistance.
