FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, namely, to steel sheets with a metallic coating used in the automotive industry. Metallic coating contains, in wt.%: from 2.0 to 24.0 of zinc, from 7.1 to 12.0 of silicon, from 1.1 to 8.0 of magnesium, not more than 3.0 of iron and additional elements selected from Pb, Ni, Zr or Hf, while the mass content of each additional element does not exceed 0.3, the rest is aluminum and inevitable impurities. Ratio of Al/Zn in the coating is more than 2.9.
EFFECT: increased corrosion protection before and after molding.
