    • A sheet metal made from a ferritic stainless steel alloy which has an improved corrosion resistivity and is suitable for use in manufacturing exterior building material, in particular, roofing material, by means of forming process such as roll-forming, without formation of pocket wave. The steel alloy comprises 10-32 wt % of Cr and 0.005-0.1 wt %, in total, of C and N, the balance being Fe and unavoidable impurities. The sheet metal has been processed to present a mechanical property that, when tested in a tensile test conducted for a test piece sampled in the widthwise direction of cold-rolling and measured at the elastic limit reached in the test, a strain ratio is equal to or greater than 2.5.The method of making the sheet metal comprises the steps of: cold rolling a steel slab into a sheet metal, subjecting the thus obtained sheet metal to final annealing, subjecting the sheet metal to skin-pass rolling, and, subjecting the resulting sheet metal to aging process at a temperature of 200.degree.-550.degree. C. for a time period of more than 5 seconds and less than 48 hours.
