A steel sheet coated with a metallic coating is provided. The coating includes from 1.0 to 22.0% by weight of zinc, from 0.1 to 1.0% by weight of titanium, from 1.6 to 15.0% by weight of silicon, below 0.5% by weight of magnesium, below 0.05% by weight of La or Ce or both, below 0.2% by weight of Sn and optionally, less than 0.3% by weight of additional elements chosen from Sb, Pb, Ca, Mn, Cr, Ni, Zr, In, Hf or Bi. A balance of the coating includes aluminum and optionally unavoidable impurities and residual elements. A microstructure of the coating does not include Al—Zn binary phases.
