Data from the Perfiles de Aluminio standard profile catalogue, 2026 edition, published with its permission. The weight per metre is the one declared by the manufacturer; the actual weight may vary within the tolerances of the standard. The equivalent cross-section is calculated with a density of 2.699 g/cm³. Standard length: 6 m.
