Overview

prEN 10219-1 rev defines the technical delivery conditions for cold-formed welded structural hollow sections of non-alloy and fine-grain steels. The standard applies to hollow sections formed cold (without subsequent heat treatment) in common geometric forms - circular, square and rectangular - and establishes the framework for material acceptance, testing, inspection and marking. This document is intended for manufacturers, specifiers, fabricators and inspection bodies working to CEN/EN requirements for construction steelwork.

Key Topics

• Scope and applicability: Cold-formed welded structural hollow sections produced for structural use; covers delivery requirements rather than dimensional tolerances.
• Information for ordering: The standard describes mandatory and optional information that purchasers must supply to manufacturers (grade, dimensions, form, delivery condition, inspection level and any special tests).
• Manufacturing and supply conditions: Defines manufacturing process considerations and the required supply condition for products formed cold without subsequent heat treatment.
• Inspection and testing: Framework for inspection types, frequency of testing, sample selection and test report contents to demonstrate conformity with the standard.
• Marking and documentation: Requirements for product marking and inspection documentation to enable traceability and compliance with construction product regulations.

Practical keywords: cold-formed welded hollow sections, technical delivery conditions, structural steel, inspection, testing, marking, CEN, EN 10219.

Applications

This standard provides direct practical value in the specification, procurement and quality assurance of structural hollow sections used in:

• Building and civil engineering frames and load-bearing members
• Architectural and façade systems where hollow sections form part of structural envelope
• Fabricated assemblies, trusses and modular steel elements
• General structural fabrication where consistent material, testing and documentation are required

Key benefits for users:

• Consistency in material acceptance criteria and inspection practices across suppliers
• Traceability through standardized marking and inspection documentation
• Risk reduction by specifying clear testing and sampling regimes that support structural performance and regulatory compliance

Related Standards

prEN 10219-1 rev sits in a series of EN documents on cold-formed hollow sections; relevant companion standards include:

• EN 10219-2 / EN 10219-3 - related parts covering technical delivery details, and tolerances/dimensions/sectional properties (check the latest part numbering applicable in your national adoption)
• prEN 10219-2:2016 - references and cross-links on testing, inspection and delivery conditions
• EN 10020 / EN 10168 / EN 10204 - normative references for steel grade classification, inspection documents and types of inspection certificates

For purchasers and manufacturers, use prEN 10219-1 rev as the primary reference for delivery conditions and combine it with the dimensional and tolerance parts when preparing specifications and contracts. Always confirm the applicable national implementation and any superseding parts when writing procurement or compliance documentation.

prEN 10219-2:2016 (E)
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.
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.

Option 2.7 Weld repairs to the body of structural steel hollow sections are permitted.
7.4.5 Any permitted weld repairs shall be carried by operators qualified in accordance with
EN ISO 9606-1. Welding repair procedures shall be issued in a written form and qualified in accordance
with EN ISO 15607, EN ISO 15609-1 and EN ISO 15614-1.
The repaired hollow section shall conform to all the requirements of this European Standard.
