Developments and Properties of Zn-Mg Galvanized Steel Sheet 'Dymazinc' Having Excellent corrosion Resistance

摘要

"DYMAZINC" (hot-dip galvanized steel sheets having an extra thick and highly corrosive resistant coating) was develop with the objective of extending the lon- gevity of hot-dip galvanized steel sheets. The characteristics of DYMAZINC are that it has a thick coating weight rivaling that of post-dip galvanized steel sheets and that it contains special elements such as Mg in its coating layer.
