Fabricated to EN10219-1 standards, the S235JRH grade offers a minimum yield strength of 235 MPa, tensile strength ranging from 360–510 MPa, and minimum elongation of 24%, ensuring dependable structural performance for construction, industrial frameworks and infrastructure applications globally.
Understanding EN10219-1 S235JRH Pipe
The product is intended as a welded structural hollow segment, either cold-formed or hot-finished. It is made to rigorous European requirements for chemical composition and mechanical qualities.
The material has regulated carbon concentration (max 0.17% – 0.20%) and manganese (max 1.40%) which gives excellent weldability without preheating for typical thicknesses. It offers a reliable load carrying capability with a minimum yield strength of 235 MPa. The tensile strength is between 360 MPa and 510 MPa, such that the pipe can withstand static and dynamic loads in structural systems.
You benefit from its excellent ductility during fabrication. Cold-forming operations become simpler, and surface finishes remain smooth. This makes installation faster and reduces labor costs on site.
Technical Specifications & Chemical Composition
Below are the key technical parameters for the product:
| Parameter | Value |
|---|---|
| Grade | S235JRH |
| Outer Diameter | 60.3mm – 2032mm (2" – 80") |
| Wall Thickness | 4mm – 100mm |
| Minimum Yield Strength | 235 MPa |
| Tensile Strength | 360 – 510 MPa |
| Minimum Elongation | 24% |
| Carbon Content (Max) | 0.17% – 0.20% |
| Manganese (Max) | 1.40% |
| Standard | EN10219-1 |
| Delivery Time | 7 Days (fastest) |
The controlled chemical balance ensures you receive pipes with consistent mechanical behavior and excellent weld integrity. This is crucial when fabricating large steel structures or frameworks requiring multiple joints.
Key Advantages for Structural Applications
Choosing the product means you gain multiple practical benefits. The material's stable mechanical properties support various construction and industrial needs. Its good weldability allows your team to work efficiently without complex pre-weld treatments.
Cost efficiency is another big element. S235JRH is a cost-effective solution with dependable performance, compared to higher strength classes. It is thus perfect for tasks with little budgets but high demands on quality.
Dimensional precision is maintained throughout the manufacturing cycle. Hot finished or cold formed, you get hollow pieces with tight tolerances. This makes assembly easier and limits modifications on location.
It is a material that may be used for many things, such as building frames, bridge supports, mechanical constructions and general engineering work. It's flexible in the manufacture, so you may request varied diameters, wall thicknesses and lengths to fit your particular demands.

We obtain raw materials from reliable Chinese steel mills such as Shagang, TISCO and Bao Steel. Every batch is subjected to rigorous quality control, from plate inspection to testing of final pipe. Our innovative heat treatment process strengthens weld seams, and we use expert inspection equipment to find any faults before shipping.
“Full traceability is provided. Each pipe has documentation on the source of raw material, the production process and the findings of the final inspection. Our company has passed API 5L, ISO9001, ISO14001 and ISO18001 certificates, which prove we have good quality, environmental protection and occupation health and safety.
Beyond pipe manufacturing, we offer value-added services for EN10219-1 S235JRH Pipe including welding, perforating, expansion processing, and anti-corrosion treatments such as hot-dip galvanizing, FBE coating, and 3LPE coating. These services enhance pipe durability and adapt products to challenging environments.
Quality Documentation & Project Support
For international projects complete documentation is necessary. We supply Mill Test Certificates (MTC) according to EN 10204 3.1 including chemical composition and mechanical test results. You also get dimensions inspection results for outer diameter, wall thickness, length and straightness.
If your project requires third party verification, we can work with organisations like as BV, TUV or Intertek. Further non-destructive testing (NDT), surface treatment reports and CE marking documentation are available on request.
Our technical staff will keep professional contact along the purchase process. From customised cutting to unique coating solutions and particular branding and packaging, we respond to your needs. This assistance helps with fast project approval and timely construction progress.
FAQ
Q：What is the difference EN10219-1 S235JRH and S355J2H?
A: It has lesser yield strength (235MPa vs 355MPa) and is impact tested at room temperature. S355J2H is tested at -20°C to improve cold toughness. If your project isn't going to be exposed to severe cold and is in mild climate, S235JRH is a cost-effective option with enough strength.
Q：Can this pipe be hot-dip galvanized?
A： Yes. The product is quite compatible with the galvanising procedures. This offers good corrosion protection in the long term notably for outdoor or exposed structural applications.
Q: Which welding process may be used for S235JRH?
A: The material has exceptional weldability due to its low carbon equivalent. typical thicknesses are often used without pre-heat using typical MIG, TIG, or SAW procedures. This makes it easier and cheaper for manufacture.
Q: Does S235JRH comply with CE marking requirements?
A: Yes. The product might be CE marked when it is produced in a certified factory production control system. This is needed for permanent buildings inside the European Economic Area.
Q: Which quality documentation should I seek before ordering?
A: Mill Test Certificate (MTC) 3.1 as per EN 10204 with chemical composition and mechanical test findings. Request for dimensional inspection reports, weld inspection records and visual inspection reports; Consider 3rd party inspection and other NDT for essential projects.
