scope:

This part of this European Standard specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical conditions to those obtained in the hot formed product. The general conditions (product characteristics, test methods and performance criteria that apply under the Construction Products Regulations) are specified in prEN 10210-1 and the requirements for tolerances, dimensions and sectional properties in prEN 10210-3. NOTE 1 prEN 10210-1 covers provision of the Construction Products Regulations (CPR) to fulfil European law for construction products. The technical delivery conditions are described within prEN 10210-2 in combination with Clauses 2, 3, 4, 5, 7 and 8 of prEN 10210-1. NOTE 2 The attention of users is drawn to the fact that whilst cold formed grades in prEN 10219-2 can have equivalent mechanical properties to hot-finished grades in prEN 10210-2 the sectional properties of square and rectangular hollow sections in prEN 10210-3 and prEN 10219-3 are not equivalent. NOTE 3 A range of material grades is specified in this standard and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5 and EN 10025-6. NOTE 4 Seamless and welded hollow sections for offshore structures are covered in EN 10225.
