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.
