ZN-AL ALLOY PLATED STEEL PANEL EXCELLENT IN ROLL MOLDABILITY AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent the generation of plating pickup at the time of roll molding and to suppress the peel of a film. SOLUTION: When an organic resin film with a coating area ratio of 75-95% is formed on the surface of a molten Zn-5% Al alloy or molten Zn-55% Al alloy plated steel panel, an organic resin treatment solution is applied by a three-roll type roll coating apparatus limitted in roll material quality and roll surface roughness.
