Abstract
Profile for rolling shutter sheet, 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 said walls in an asymmetrical plane, optionally provided with openings and finished in semicircular hook, in concavity in the lower side, and by a lower cavity with a narrow opening in its base, formed by an incoming recess of said walls, giving rise to a transverse partition and a lower right-angled fin derived from one of said walls, whereby said opening has asymmetry in correspondence with said upper top, being located in the closing seaming at a point of the periphery of the profile.
