EN 10210 is the European standard for hot-formed structural hollow sections made of non-alloy and fine-grained steels. It specifies the technical requirements for hot-formed steel tubes used in load-bearing structures such as buildings, bridges, and machinery.
This standard complements EN 10219 (cold-formed structural hollow sections), and together they form the primary standard system for structural steel tubes in Europe.

Common grades of EN 10210 include S235JRH, S275J0H / J2H, and S355J0H / J2H / K2H.
Mechanical Properties：
| Grade | Yield Strength/ ReH (MPa) | Tensile Strength/ Rm (MPa) | Elongation/ A (%) | Impact |
| S235JRH | ≥235 | 360 – 510 | ≥24 | JR（+20°C） |
| S275J0H | ≥275 | 410 – 560 | ≥23 | J0（0°C） |
| S275J2H | ≥275 | 410 – 560 | ≥23 | J2（-20°C） |
| S355J0H | ≥355 | 470 – 630 | ≥22 | J0（0°C） |
| S355J2H | ≥355 | 470 – 630 | ≥22 | J2（-20°C） |
| S355K2H | ≥355 | 470 – 630 | ≥22 | K2（-20°C, higher energy） |
Take S355J2H as an example:
S: Structural Steel
355: Minimum yield strength of 355 MPa
J: Impact resistance
J2H = The most commonly used structural grade worldwide
K2H = Offshore / Cryogenic / High-safety-grade projects
H：Hollow Section
It is the most cost-effective option among these grades, offers excellent weldability, and is suitable for light-gauge steel structures and general non-load-bearing structures in construction.
It offers excellent low-temperature toughness and is easy to weld, making it widely used in bridge structures, high-rise buildings, and lifting equipment.
EN 10210 does not define the chemical composition of all steel grades on its own, but rather serves as a reference standard formed by cross-referencing the EN 10025 series of structural steel standards and supplementary restrictions.
General Requirements for Chemical Composition Control：
| Element | Maximum content |
| C | ≤ 0.22% |
| P | ≤ 0.035% |
| S | ≤ 0.035% |
| N | ≤ 0.012% |
S235JRH has a carbon content of ≤ 0.17%, making it a low-carbon steel with excellent weldability.
S355J0H / J2H / K2H Chemical Composition：
| Element | Content |
| C | ≤ 0.22 |
| Mn | ≤ 1.60 |
| Si | ≤ 0.55 |
| P | ≤ 0.035 |
| S | ≤ 0.035 |
| N | ≤ 0.012 |
Carbon Equivalent (CEV) Requirements
EN 10210 emphasizes control of weldability; the formula for calculating carbon equivalent is:
| Grade | CEV Limits (Typical) |
| S235 | ≤ 0.35 |
| S275 | ≤ 0.40 |
| S355 | ≤ 0.45 |
The lower the CEV, the easier it is to weld, and the lower the risk of cold cracking.
EN 10210 is produced using a hot-finished process, which eliminates residual stresses in the material, resulting in a more uniform microstructure and improved dimensional stability.
Building Structures (Construction)
· Steel buildings
· High-rise structures
EN 10210 features strict carbon equivalent control and is generally designed for low-carbon applications.
It offers excellent weldability and is suitable for on-site welding. Its high-safety-grade design perfectly meets the safety and reliability requirements of critical engineering projects.
Bridge Engineering
· Bridge support structures
· Main girder auxiliary structures
The commonly used steel grade S355J2H / K2H is suitable for environments as cold as -20°C or even lower, and offers consistent impact resistance.
It can also be used in conjunction with anti-corrosion coatings to enhance corrosion resistance and extend service life.

· Offshore wind towers
Public Infrastructure
· Stadium structures
· Exhibition halls

EN 10210 is a European standard that specifies the technical requirements for hot-formed structural hollow sections made of non-alloy and fine-grained steels.
EN 10210 specifies hot-finished structural hollow sections with low residual stress and excellent strength and toughness, making them suitable for structural engineering applications with high performance requirements, such as bridges, marine engineering, and high-rise buildings.
EN 10219, on the other hand, refers to cold-formed hollow sections for welded structures. These have lower production costs but relatively higher residual stresses and are primarily used in general construction and ordinary structural engineering.
EN 10210 does not specify the manufacturing method; the product may be a seamless pipe, a welded pipe, or any other product that undergoes heat treatment after forming.
The most important requirement is that it undergoes a process involving hot forming and heat treatment.
