The invention relates to a sheet metal blank for producing a heat-shaped and press-hardened steel sheet component (7) in a heat-shaping method, wherein, in a heat treatment step, the sheet metal blank (6) is heat-treated to above the material-specific austenitizing temperature Ac3; in an inserting step, the heat-treated sheet metal blank (6) is inserted into a shaping die (3); in a press-hardening step, the sheet metal blank (6) is heat-shaped and cooled, forming the sheet metal component (7), which, in a removal step, is removed from the opened shaping die (3), wherein the sheet metal blank (6) has, as a base material (10), a hardenable steel having a metallic scale protection coating on both sides. According to the invention, the metallic scale protection coating is formed as a copper layer (11). In the heat treatment step, the copper layer (11) converts into an electrically conductive copper oxide layer (13) bonded to the steel base material (10).
