ABSTRACT:
A process for producing a one-piece, structured metal sheet having an interior with a hole, provides a predetermined, curved outer contour and inner contour that delimits the hole. A smooth, shaped blank is produced, having an outer edge substantially concentrically outside the predetermined outer contour and an inner edge substantially concentrically outside the predetermined inner contour. A structure, which preferably has formations running substantially radially, is then stamped into the metal sheet so that the sheet is formed with an approximately uniform degree of deformation in an inner boundary region and an outer boundary region. A metal sheet for a catalyst carrier body has an interior hole, an outer contour, an inner contour delimiting the hole and a structure with formations running approximately in radial direction. The metal sheet is produced in one piece and in particular is seamless.
