Arvedi LEONARDO hot finished structural hollow sections are HFI welded tubes made in accordance with standard EN10210-1/2/3 as well as the special features of cold-formed welded tubes, such as: precision, control and uniformity of geometry and dimensions, • absence of eccentricity, • close tolerances on wall thickness, • precision on the corner radius, • excellent surface finishing, both in terms of absolute roughness and surface scale (in line with the prescriptions of standard EN 10163-3 class D, subclass 3), • customizable seizes and lengths. CERTIFIED STEEL For the steel grades included in the standard EN10210-1 Arvedi LEONARDO Hot Finished Hollow Sections supplies are CE certified and are accompanied by EN10204 3.1 certificate and declaration of performance (in accordance with Regulation EU 305/2011). Arvedi LEONARDO Hot Finished Hollow Sections is CE certified for construction products: EN 10210 license no. CE 1608 CPR P063. Arvedi LEONARDO have all the benefits of hot finished tubes, such as: • homogeneity of the technical characteristics: workability, weldability, ductility, plasticity and bendability, • absence of residual stresses in the section corner areas and the tube welding area, • suitability for weld on the corner over the whole Arvedi size range, overcoming the limits defined in Eurocode 3 (also for wall thicknesses> 12.5 mm); are optimal for use in building steel structures in seismic areas thanks to the extensive plastic field they have a large capacity to absorb energy, a characteristics with makes them ideal for the constructions, structures, and machinery subject to sudden loads, repeated loads, fatigue and vibrations are ideal for curving and bending and generally have a high workability Arvedi LEONARDO, thanks to the type of full body normalizing heat treatment: HOT FINISHED Welding Relations
