HOT-FINISHED LEONARDO TUBE
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.
