METAL-COATED STEEL STRIP

摘要

A method of forming a metal coated strip, such as a steel strip, is disclosed. The method comprises solidifying a molten coating of an Al-Zn-Si-Mg alloy on the strip with a high rate of cooling only after a sufficiently strong, solid supporting network of alpha phase dendrites has been established in the coating and before a Mg<SUB>2</SUB>Si phase has started to form in the coating.
