The perfection of cold-formed products with all the benefits of hot finished ones Hot-finished round, square and rectangular hollow sections for structural applications are produced by Arvedi Tubi Acciaio in European metric formats in accordance with standards EN 10210-1/2. Arvedi hot-finished structural hollow sections, to the special characteristics of the cold-formed welded sections such as: geometric and dimensional precision, control and uniformity absence of eccentricity close tolerances on wall thickness precision of corner radius excellent surface finish, both in terms of absolute roughness and surface scale in line with the prescriptions of standard EN 10163-3 class D, sub-class 3 can be added all the benefits of hot finished tube and sections, such as: homogeneity of the technical characteristics: processability, weldability, ductility, plasticity and bendability absence of tension in the hollow section edge areas and the welding zone suitable for edge welding over the whole Arvedi size range, exceeding the limits defined in Eurocode 3 (also for wall thicknesses >12.5 mm) Arvedi hot-finished tubes and hollow sections: optimal for application in the construction of steel structures in seismic areas as they fully satisfy the prescriptions of the Ministerial Decree relative to construction products (point 11.3.4.9); thanks to the wide plastic range they have a large capacity to absorb energy, a characteristic which makes them ideal for constructions, structures, installations and machinery subject to sudden, repeated loads, fatigue and vibrations; are ideal for bending and generally present a high degree of workability Moreover, Arvedi hot-finished tubes and hollow sections, compared to those of the best competition, also add: control of the position of the internal welding bead, always in the centre of the larger side, (optional) removal of the internal welding bead, The same thickness on the sides and corners of the hollow section; Absence of eccentricity both in the hollow section and along the tube; Uniform thickness and weight along the whole length of each tube or square/rectangular hollow section Customized sizes and lengths The range of Leonardo hollow sections can be made in the following steel grades: base structural steels, non-alloyed: S235JR - S275J2H – S355J2H fine grain structural steels: S275NH – S355NH - S460NH (and NLH) steels with improved resistance to atmospheric corrosion: S235J0W – S355J0W – S355J0WP Arvedi Leonardo tubes and hollow sections are supplied with test certificate in accordance with EN10204. Moreover, hollow sections and steels included in standards EN 10210-1/2 are CE-certified and covered by performance certificate in accordance with directive UE 305/2011. Arvedi Tubi Acciaio is CE-certified for construction products: EN10210: licence no. CE 1608 CPR P063.
