Abstract: An expanded metal produced by repeated penetration of a movable cutting die including teeth into a metal sheet that is run through an expansion device in a feed direction, the expanded metal including a plurality of loops, wherein the loops include bars that envelop loop openings and that are connected in nodes, wherein each of the loops includes a loop opening length measured in the feed direction along a line from a node center to node another center of two nodes that are arranged behind one another in the feed direction, wherein each of the loops includes a loop opening width that is measured transversal to the feed direction along a line from a node center to a node center of two nodes that are arranged adjacent to each other transversal to the feed direction.

Abstract: A method for producing an expanded metal, the method including producing a sheet of the expanded sheet metal by introducing openings through one expansion blade wherein all the openings are configured as diamond shaped loops without a material loss and defined by a loop width, a loop length and a loop shape; and forming the diamond shaped loops respectively by four linear bars that are defined by a bar width and a bar thickness wherein two of the four linear bars are respectively connected at four nodes; arranging plural of the diamond shaped loops in columns adjacent to one another and in rows adjacent to one another; and forming first columns of first diamond shaped loops different from second columns of diamond shaped second loops in a loop width or in a loop length respectively measured from a node center to a node center.

Abstract: The invention relates to an expanded metal, comprising: a sheet of expanded sheet metal including openings configured as loops that are essentially introduced without a material loss and which are defined by a loop width, a loop length and a loop shape; and bars that envelop the loops and that are defined by a bar width and a bar thickness, wherein plural loops are arranged in columns behind one another and in rows adjacent to each other. It is an object of the invention to find new applications for expanded metal in the production of automobiles by providing an expanded metal with new properties. The object is achieved by an expanded metal with the features of claim 1, in particular its characterizing features, wherein columns of first loops differ from columns of second loops in a loop width and/or in a loop length so that the sheet of the expanded metal is provided with openings with different loop shapes.
