<p>A process of hot-dip coating a ferrous metal strip with the zinc - 5% aluminum eutectic alloy in which the clean strip is continuously passed through a zinc-aluminum eutectic alloy bath maintained at a temperature between about 775.degree.F and 825.degree.F and impinging on the fluid eutectic alloy coating as it is withdrawn from the bath jets of steam heated to at least 900.degree.F to control the coating weight and retard the solidification of the zinc-aluminum eutectic alloy coating. The resulting zinc-aluminum eutectic alloy coated strip is formable at room temperature, and the coating is free of surface ripples and large spangles.</p> |
