Overview of EN 10210 S355JRH Steel Pipe
EN 10210 S355JRH is a premier hot-finished structural steel hollow section specified under the European standard EN 10210-1 and EN 10210-2. The designation ‘S’ stands for Structural steel, ‘355’ represents the minimum yield strength of 355 MPa (for wall thicknesses ≤ 16mm), ‘JR’ indicates impact testing at 20°C (min 27J), and ‘H’ signifies its form as a hollow section. Unlike cold-formed sections, EN 10210 pipes are hot-finished to eliminate internal stresses and provide superior dimensional stability, making them the industry standard for high-load structural applications in civil engineering, bridge construction, and heavy industrial frameworks.
Shandong Tanglu Metal Material Co., Ltd. supplies high-grade EN 10210 S355JRH pipes in various geometric forms, including Circular (CHS), Square (SHS), and Rectangular (RHS). These sections are produced through seamless or welded processes followed by a hot-finishing treatment, ensuring uniform mechanical properties and a refined grain structure. For B2B buyers, S355JRH provides a high-strength, reliable structural conduit that maximizes load-bearing efficiency while maintaining excellent weldability and fabrication versatility.
Key Features and Technical Advantages
The primary advantage of EN 10210 S355JRH steel pipe is its exceptional structural integrity derived from the hot-finishing process. This manufacturing method ensures that the section has uniform wall thickness and a consistent metallurgical structure free from the residual stresses typical of cold-forming. It exhibits superior resistance to buckling and compression, which is critical for vertical columns and large-span trusses. The S355 yield grade offers a 50% increase in load capacity over standard S235 steel, allowing for significant material savings and lighter structural designs.
Our EN 10210 pipes are available in a massive range of sizes, with outer diameters up to 1219mm for circular sections and 500x500mm for square sections. The grade features precisely controlled carbon and manganese levels, ensuring high-quality joint integrity using all standard industrial welding methods (GMAW, SAW). For projects requiring enhanced durability, we provide pipes with specialized surface treatments including hot-dip galvanizing or advanced anti-corrosion coatings (3PE/FBE), ensuring the longevity of the structure in aggressive atmospheric or marine environments.
Main Applications of EN 10210 S355JRH Pipe
EN 10210 S355JRH steel pipe is the definitive material for modern structural engineering. It is extensively used in the construction of large-scale building skeletons, airport terminals, and highway bridges where high strength and dimensional precision are required. In the offshore sector, it serves as the essential material for platform trusses, jacket structures, and specialized subsea frames due to its reliable impact toughness and structural stability.
Beyond civil construction, S355JRH hollow sections are a vital component in the manufacturing of heavy machinery, crane booms, and agricultural equipment frames.

❓ Frequently Asked Questions
What is the difference between S355JRH and S355J2H?
The main difference is the impact test temperature. S355JRH is tested at 20°C (JR), while S355J2H is tested at -20°C (J2). J2H offers better fracture toughness in colder environments.
Why choose hot-finished EN 10210 over cold-formed EN 10219?
Hot-finished sections have uniform mechanical properties, higher load-bearing capacity, and no internal stresses from forming, making them safer for critical structural applications like high-rise columns.
What is the equivalent of S355JRH in the US standard?
The closest equivalent is ASTM A501 Grade B, which also covers hot-formed structural tubing. It also corresponds roughly to the high-strength version of ASTM A500.
Can these sections be galvanized?
Yes, EN 10210 hollow sections are excellent for hot-dip galvanizing. The hot-finished surface provides superior zinc adhesion, ensuring long-term rust protection.
What are the common end preparations?
Standard preparations are square cut (PE). For larger CHS sections intended for welding, beveled ends (BE) can be provided upon request.
