Product introduction
Standard & Product Definition
Standard: EN 10219 (split into EN 10219-1: technical delivery conditions; EN 10219-2: dimensions, tolerances, section properties) – European specification for cold-formed welded structural hollow sections (non-alloy/fine-grain steels), including circular pipes.
Grade Nomenclature:
S: Structural Steel;
235: Min yield strength 235 MPa (t ≤16 mm);
JR: Room-temperature (+20°C) impact test requirement;
H: Hollow section-specific grade.
Material Number: 1.0039; Production Process: ERW (Electric Resistance Welding) is the most common, cold-formed & welded, no post-weld normalization required in standard delivery.
Key Mechanical & Chemical Properties
Mechanical Performance
| Property | Value | Notes |
|---|---|---|
| Yield Strength (ReH) | ≥235 MPa (t ≤16 mm); ≥225 MPa (16＜t ≤40 mm) | Thickness-dependent decrease |
| Tensile Strength (Rm) | 360–510 MPa | |
| Elongation (A) | ≥24% | Ensures good ductility |
| Impact Toughness (KV) | ≥27 J (average at +20°C) | Single specimen min ≥20 J |
Typical Chemical Composition (mass%)C ≤0.17%, Si ≤0.35%, Mn ≤1.60%, P ≤0.035%, S ≤0.035%;low impurity, excellent weldability (compatible with common arc welding processes like SMAW, GMAW, SAW).
Common Sizes & Tolerances
Outer Diameter (OD): Typically 42.4 mm to 610 mm;
Wall Thickness (WT): 2.0 mm to 12.7 mm (up to 40 mm per standard limit);
Length: 6 m (standard), 12 m, or cut to custom lengths;
Tolerances: OD and WT strictly comply with EN 10219-2, ensuring interchangeability for structural projects.
Application Scenarios
Civil Engineering: Steel frames, trusses, bridges, stadiums, workshop buildings;
Mechanical Fabrication: Machinery housings, support columns, conveyor lines;
Infrastructure: Municipal pipe racks, sign poles, temporary works;
General Structural Uses where weldability and moderate strength are prioritized, cost-effective alternative to seamless structural pipes.
Quality Control & Certification
Mandatory tests: Tensile, impact, flattening, weld seam inspection (ultrasonic/eddy current);
Documentation: Mill Test Certificate (MTC) per EN 10204 3.1/3.2;
CE marking compliant with CPR (Regulation (EU) No 305/2011) for construction applications in the EU market.
Comparison with Similar Grades
vs EN 10210 S235JRH: EN 10210 focuses on hot-finished hollow sections; EN 10219 is cold-formed welded, with tighter dimensional tolerances and lower cost for standard structures;
vs S355J2H (EN 10219): S355 offers higher yield strength (355 MPa) but at a premium; S235JRH is more economical for non-high-stress scenarios.

Packaging, transportation and delivery
Packaging, transportation and delivery
At Hebei Huayang Steel Pipe Co., Ltd., we apply standardized and reliable packaging solutions for all our steel pipe products. Our pipes can be securely packed by hexagonal bundling or circular bundling according to product diameter, wall thickness and customer requirements. Each pipe end is protected with high‑strength plastic pipe caps to avoid collision damage, dust and moisture during transportation and storage. The whole bundle is firmly wrapped with durable woven bags to enhance stability and prevent scratches or deformation.
We support a complete range of transportation methods to satisfy global customers, including road transportation, railway transportation, sea freight and container shipping. Based on our strategic location in Cangzhou, Hebei Province, we enjoy convenient access to major ports such as Tianjin Port, which greatly improves logistics efficiency and reduces transportation costs.
For standard specifications and normal order quantities, the general delivery time is about 30 days after order confirmation and deposit receipt. For large‑scale orders, special sizes or customized processing requirements, our production and sales team will formulate a detailed production plan and provide an accurate delivery schedule accordingly to ensure on‑time supply and stable performance for projects and clients worldwide.
Strict quality control
1. During and after the production, experienced quality inspectors randomly check the products to ensure that each steel pipe is qualified for production and application.
2. A nationally recognized laboratory with CNAS certification and certification by French Classification Society.
3. Have CNOOC access certificate, KOC oil company access network, ADNOC Abu Dhabi oil company access network, Petrobras access network, etc.
4. Accept the inspection by the third party designated/paid by the buyer, such as SGS and BV.
