Profile for roller blind slat, tubular type obtained in metal sheet folded and closed by seaming, characterized because it is constituted by two straight walls and parallel to each other, determining a hollow central space, by an upper finish formed by the mutual joining of the cited walls in an asymmetrical plane, optionally provided with openings and ending in a straight hook at an acute angle towards the blade itself, and through a lower cavity with a narrow opening at its base, formed by an incoming recess of said walls, giving rise to a transversal septum and a lower fin at an acute angle entering the cavity, derived from one of said walls, whereby said opening has asymmetry in correspondence with said upper top, the closing seaming being located at a point of the periphery profile.
