The invention relates to a panel and method for producing a formwork panel for walls, slabs, floors, beams, posts or any concrete structure comprising a wire-mesh metal sheet (2) reinforced with a plurality of stiffeners (3) consisting of rigid profiled metal bars secured to one surface of said wire-mesh metal sheet (2) arranged parallel to one another and spaced apart at predetermined intervals, and with ribs integrated into the wire mesh of the wire-mesh metal sheet (2) spaced apart at predetermined intervals and intersecting the stiffeners (3). The wire-mesh metal sheet (2) is attached to the stiffeners (3), at least by means of an assembly carried out at least at one intersection between the ribs (4) and the stiffeners (3). The panel (1) is characterised in that the assembly is carried out so that at least one metal portion of the stiffener (3) and at least one metal portion of the rib (4) hold the stiffener (3) on the wire-mesh metal sheet (2) by clinching the metal portion of the stiffener (3) in the metal of the rib (4) or by cinching the metal portion of the rib (4) in the metal of the stiffener (3).
