EN 10210-1: Technical standards for hot-finished hollow sections
Scope of EN 10210-1
This European standard specifies the delivery requirements for hot-finished hollow sections of various cross-sections: circular, rectangular, square, and elliptical. At EV Group China, we supply products that comply with hot-forming methods, as well as products that have undergone cold forming followed by heat treatment to achieve characteristics identical to their hot-finished counterparts.
Geometric parameters, tolerances, and design cross-sections are regulated in the EN 10210-2 standard.
Expert recommendation: the choice of steel grade should be based on design loads and the corrosivity of the operating environment.
| Steel Grade | EN Material Number |
|---|---|
| S235JRH | 1.0039 |
| S275J0H | 1.0149 |
| S275J2H | 1.0138 |
| S355J0H | 1.0547 |
| S355J2H | 1.0576 |
| S355K2H | 1.0512 |
The mechanical properties of the metal products supplied by EV Group China fully comply with the specifications of EN 10025-2 and EN 10025-3.
EN 10210-2: Tolerances and geometric parameters for hot-finished sections
Technical parameters of the EN 10210-2 standard
This part of the standard establishes limit deviations for hot-finished sections with wall thicknesses up to 120 mm. The main size ranges are:
- Circular sections: outer diameter up to 2500 mm.
- Square sections: dimensions up to 800×800 mm.
- Rectangular sections: dimensions up to 750×500 mm.
- Elliptical sections: dimensions up to 500×250 mm.
Calculation methods for geometric characteristics of cross-sections for design purposes are provided in Annex A, and reference data for standard sizes is provided in Annex B.
EN 10210-3: High-strength and weather-resistant hollow sections
EN 10210-3 Specification
EN 10210-3 sets out delivery requirements for high-strength and corrosion-resistant metal products (seamless and welded). The standard covers sections that have undergone hot forming or heat treatment at temperatures above 580 °C to stabilize their structure.
Technical note: The steel grades in this standard are harmonized with the requirements of EN 10025-4, EN 10025-5, and EN 10025-6. For offshore structures, please refer to the requirements of EN 10225.
