Activity in the development of hotdip galvanizing alloys has been quite successful in achieving two major goals. First, the use of a zinc-nickel bath provides a workable solution to the problem of batch galvanizing reactive steels, to achieve both an attractive surface appearance and a thin, durable and protective coating. Second, for continuously galvanized steel products, specific zinc-aluminum alloys have provided a means to greatly increase corrosion resistance, increase the maximum use temperature of zinc coatings, achieve the fabrication of severely formed products without damage to the zinc alloy coating, and allow such products to be formed from prepainted as well as unpointed coated steel.
