EN 10210 Hot Finished Structural Steel Pipe
EN 10210 Structural Steel Pipe Manufacturer
Huayang Steel Pipe manufactures EN 10210 hot finished structural steel pipe for construction, infrastructure, industrial facilities, bridges, towers, columns, mechanical structures, and other load-bearing applications.
EN 10210 specifies technical delivery conditions for hot finished structural steel sections in circular, square, rectangular, and elliptical forms. EN 10210-1 covers requirements for steel grades, chemical composition, mechanical properties, manufacturing and testing, while EN 10210-2 specifies dimensions, tolerances and sectional properties. The standard covers hot-finished seamless, electric welded and submerged arc welded structural sections.
Huayang provides EN 10210 structural steel pipe through applicable HFW/ERW and LSAW manufacturing processes, with customized outside diameter, wall thickness, length, steel grade, inspection and surface treatment according to project requirements.

Common EN 10210 structural grades include S235JRH, S275J0H, S275J2H, S355J0H, S355J2H and S355K2H. Fine grain grades such as S275NH, S275NLH, S355NH, S355NLH, S420NH, S420NLH, S460NH and S460NLH are also included in the broader EN 10210 grade system.
For the main grades relevant to general structural applications:
| Steel Grade | Yield Strength Min. MPa* | Tensile Strength MPa | Typical Application |
|---|---|---|---|
| S235JRH | 235 | 360–510 | General Structural Applications |
| S275J0H | 275 | 430–580 | Structural Frameworks |

* Values shown are representative requirements for lower wall-thickness ranges. EN 10210 provides thickness-dependent mechanical properties.
EN 10210 Size and Dimension Table
For the website, I recommend presenting representative circular pipe sizes rather than trying to reproduce the entire EN 10210-2 dimensional annex.
| Outside Diameter mm | Typical Wall Thickness mm | Applicable Manufacturing |
|---|---|---|
| 48.3 | 3.0–5.0 | HFW / ERW |
| 60.3 | 3.0–6.0 | HFW / ERW |
| 76.1 | 3.0–6.0 | HFW / ERW |

| 1220.0 | 14.0–50.0 | LSAW |
| 1422.4 | 16.0–50.0 | LSAW |
The dimensions listed above represent commonly supplied sizes. Other outside diameters, wall thicknesses and lengths can be manufactured according to applicable EN 10210 requirements and project specifications.
EN 10210-2 itself covers a much broader dimensional scope, including circular sections up to 2500 mm outside diameter and wall thicknesses up to 120 mm. These values describe the standard's scope and not Huayang's production range.
EN 10210 Chemical Composition
Chemical composition is controlled according to the selected steel grade. Carbon, manganese, phosphorus, sulfur, nitrogen and carbon equivalent are controlled where applicable.
| Grade | C Max. | Mn Max. | P Max. | S Max. | CEV Max. |
|---|---|---|---|---|---|
| S235JRH | 0.17% | 1.40% | 0.040% | 0.040% | 0.35 |
| S275J0H | 0.20% | 1.50% | 0.035% | 0.035% | 0.40 |
| S275J2H | 0.20% | 1.50% | 0.030% | 0.030% | 0.40 |
| S355J0H | 0.22% | 1.60% | 0.035% | 0.035% | 0.45 |
| S355J2H | 0.22% | 1.60% | 0.030% | 0.030% | 0.45 |
| S355K2H | 0.22% | 1.60% | 0.030% | 0.030% | 0.45 |
The exact chemical composition depends on the steel grade, product thickness and applicable edition of EN 10210-1.
Mechanical Properties
| Grade | Yield Strength Min. MPa* | Tensile Strength MPa | Minimum Elongation |
|---|---|---|---|
| S235JRH | 235 | 360–510 | 26% |
| S275J0H | 275 | 430–580 | 23% |
| S275J2H | 275 | 430–580 | 23% |
| S355J0H | 355 | 470–630 | 22% |
| S355J2H | 355 | 470–630 | 22% |
| S355K2H | 355 | 470–630 | 22% |
* Yield strength varies with wall thickness. The applicable EN 10210-1 table should be used for final material verification.
Impact Toughness Requirements
The grade suffix identifies the impact toughness condition.
| Grade | Impact Test Temperature | Typical Requirement |
|---|---|---|
| S235JRH | +20°C | Charpy V-notch |
| S275J0H | 0°C | Charpy V-notch |
| S275J2H | -20°C | Charpy V-notch |
| S355J0H | 0°C | Charpy V-notch |
| S355J2H | -20°C | Charpy V-notch |
| S355K2H | -20°C | Charpy V-notch |
This makes grade selection particularly important for structural projects exposed to low ambient temperatures.
Manufacturing Process
EN 10210 is specifically associated with hot-finished structural sections. The standard covers hot-formed products, with or without subsequent heat treatment, and also permits certain products initially formed cold and subsequently heat treated above 580°C to obtain equivalent metallurgical conditions.
For Huayang's production presentation:
| Production Step | Description |
|---|---|
| Raw Material Inspection | Chemical and Mechanical Verification |
| Plate / Coil Preparation | Surface and Edge Preparation |
| Forming | Controlled Forming Process |
| HFW / ERW Welding | Longitudinal Welding |
| LSAW Welding | Submerged Arc Welding |
| Heat Treatment / Thermal Processing | According to Applicable Requirement |
| Sizing | Dimensional Calibration |
| Straightening | Geometrical Correction |
| Cutting | Fixed or Customized Length |
| Final Inspection | Comprehensive Quality Control |
EN 10210 Dimensional Tolerances
EN 10210-2 specifically covers tolerances, dimensions and sectional properties for hot finished structural sections. Its scope includes:
| Section Type | Standard Scope |
|---|---|
| Circular | OD up to 2500 mm |
| Square | Up to 800 × 800 mm |
| Rectangular | Up to 750 × 500 mm |
| Elliptical | Up to 500 × 250 mm |
| Wall Thickness | Up to 120 mm |
Again, these are the standard scope limits, not Huayang's production range.
For website presentation, the principal dimensional controls can be summarized as:
| Parameter | Control Requirement |
|---|---|
| Outside Diameter | According to EN 10210-2 |
| Wall Thickness | According to EN 10210-2 |
| Out-of-roundness | Controlled |
| Straightness | Controlled |
| Mass per Unit Length | Controlled |
| Length | According to Delivery Condition |
| End Squareness | Controlled |
| Surface Condition | Free from Harmful Defects |
Dimensional Tolerance Reference
For circular sections, representative EN 10210-2 tolerance values can be presented as follows:
| Parameter | Reference Tolerance |
|---|---|
| OD < 100 mm | ±1%, min. ±0.5 mm |
| 100 mm ≤ OD ≤ 200 mm | ±0.8% |
| OD > 200 mm | ±0.6% |
| WT ≤ 5 mm | ±10% |
| WT > 5 mm | ±0.5 mm |
| Straightness | Max. 1.5 mm / 1000 mm |
| Squareness of Sides | 90° ±1° where applicable |
| Mass | Controlled according to standard |
These values should be treated as a technical reference, with the applicable EN 10210-2 requirements used for final acceptance.
