European foreword
This document (prEN 10219-2:2016) has been prepared by Technical Committee ECISS/TC 103
“Structural steels other than reinforcements”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 10219-1:2006.
This standard consists of the following parts under the general title 'Cold formed welded structural
steel hollow sections’:
— Part 1: General
— Part 2: Technical delivery conditions
— Part 3: Tolerances, dimensions and sectional properties
It forms part of a series of standards on hollow sections together with prEN 10210-1 to prEN 10210-3.

oSIST prEN 10219-2:2016
prEN 10219-2:2016 (E)
1 Scope
This part of prEN 10219 specifies the technical delivery conditions for electric welded and submerged
arc welded cold formed structural steel hollow sections of circular, square, rectangular or elliptical
forms and applies to structural hollow sections formed cold without subsequent heat treatment.
The general conditions (product characteristics, test methods and performance criteria that apply
under the Construction Products Regulations) are specified in prEN 10219-1 and the requirements for
tolerances, dimensions and sectional properties in prEN 10219-3.
NOTE 1 prEN 10219-1 covers provision of the Construction Products Regulations (CPR) to fulfil European law
for construction products. The technical delivery conditions are described within prEN 10219-2 in combination
with Clauses 2, 3, 4, 5, 7 and 8 of prEN 10219-1.
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 10219-3 and prEN 10210-3 are not equivalent.
NOTE 3 A range of steel grades is specified in this European Standard and the user should select the grade most
appropriate to the intended use and service conditions. The grades and mechanical properties, but not the final
supply condition of cold formed hollow sections are comparable with those in EN 10025-2, EN 10025-3,
EN 10025-4, EN 10025-5, EN 10025-6, EN 10149-2 and EN 10149-3.
NOTE 4 Hollow sections for offshore structures are covered in EN 10225.
