The EN 10219 standard is a European specification that specifies the technical delivery conditions for cold-formed welded structural hollow sections made of non-alloy and fine grain steels. These hollow sections are widely used in the fields of construction, civil engineering, machinery and steel structures, and feature high strength, good weldability and a good strength-to-weight ratio.

EN 10219 is composed of two main parts

EN 10219-1

Technical delivery conditions

EN 10219-2

Tolerances, dimensions, and sectional properties

This standard specifies requirements for cold-formed structural hollow sections that are welded from hot-rolled or cold-rolled steel strip or plate, then shaped (usually by forming and welding) without further heat treatment (unless specified).

 

If you are working with square tube, rectangular tube or round hollow sections (CHS, RHS, SHS), especially in structural applications, understanding the EN 10219 standard is essential to ensure quality, compliance and performance.

EN10219-1 Scope of application:

 

EN 10219-1 specifies the technical requirements for cold-formed welding of round, square and rectangular tubes, and is applicable to hollow sections that are cold-formed or not heat-treated. It specifically specifies non-alloy high-quality steel, fine-grained non-alloy high-quality steel and fine-grained alloy special steel.

 

To summarize, in simple terms, EN10210-1 and EN10219-1 are both coordinated standards of the Construction Products Regulations (CPR). The corresponding steel pipes are generally used in construction. The difference is that EN10210-1 is suitable for hot-formed hollow pipes, while EN10219-1 is suitable for cold-formed hollow pipes that have not been heat-treated.

 

The EN 10219 specification outlines the technical delivery conditions for cold-formed welded structural hollow sections of circular, square tube, or rectangular forms. It applies specifically to sections that are cold-formed without subsequent heat treatment. This standard is significant for structural applications where hollow sections are used in building frameworks, bridges, and other engineering constructions, providing essential characteristics such as strength and impact resistance.

 

The Classified Steels

 

The steels are classified in EN 10219 as follows similarly to the classification provided in the EN 10210 standard:

• 1. Non-alloy steels

• 2. Fine-grain steels

 

For non-alloy steel structural hollow sections the designation shall consist of :

• – the number of this European Standard (EN 10219 specification);

• – (S) the capital letter S for structural steel;

• – the indication of the minimum specified yield strength for thickness ≤16mm expressed in N/mm2;

• – (JR) the capital letters JR for the qualities with specified impact properties at room temperature; or

• – (J) the capital letter J and a number 0 or 2 for the qualities with specified impact properties at 0℃ and -20℃ respectively;

• – (H) the capital letter H to indicate hollow sections.

 

For example EN 10219 specification S275J0H

• EN 10219 – Number of the European Standard

• S – Structural steel

• 275 – Minimum yield strength (N/mm2) for thickness not greater than 16mm

• J0 – Impact properties, 27J minimum at 0℃

• H – Hollow section

 

For fine grain steel structural hollow sections the steel designation consists of:

• – the number of this European Standard (EN 10219 specification);

• – (S) the capital letter S for structural steel;

• – the indication of the minimum specified yield strength for thicknesses ≤ 16 mm expressed in N/mm2;

• – (N) the capital letter N to indicate normalized or normalized rolled feedstock material or

• – (M) the capital letter M to indicate thermomechanically rolled feed-stock material;

• – (L) the capital letter L for the qualities with specified impact properties at -50 °C;

• – (H) the capital letter H to indicate hollow sections.

 

For example EN 10219 S355NLH

• EN 10219 – Number of the European Standard

• S – Structural steel

• 355 – Minimum yield strength (N/mm2) for thickness not greater than 16mm

• NL – Normalized fine grain steel feed-stock, 27J minimum at -50℃

• and H – Hollow section
