Method for coating a steel alloy

In a method of coating low and ultra low carbon cold rolled steels material with zinc by first heating a fully hard cold worked steel material in a galvanizing line multi-zone reducing atmosphere furnace having a furnace temperature controlled between 760 and 820° C., and then dipping the heated steel material in a zinc-containing molten bath to produce a zinc coated steel product, the improvement comprising maintaining the same reducing atmosphere furnace conditions but using a high strength dual phase steel composition as the fully hard cold worked steel, the composition consisting essentially of, in weight percent,

• carbon between about 0.05 and 0.12%;
• manganese between about 1.0 and 1.6%;
• phosphorus up to 0.04%;
• sulfur up to 0.02%
• silicon up to 0.10%;
• molybdenum between about 0.15 and 0.35%;
• aluminum between about 0.01 and 0.08%;
• and
• the balance being iron and incidental impurities.
