Looking for high-performance EN 10025-2 channel steel for construction or industrial projects? GNEE, a professional steel manufacturer, supplies both S355J2 and S275JR channel steel with guaranteed quality, fast delivery, and EN 10204 3.1 mill certificates. Read on to understand the differences, applications, and advantages of these steel channels.
S275JR channel steel
Key Differences Between S355J2 and S275JR Channel Steel
When choosing channel steel, the mechanical performance and project environment are critical factors:
| Feature | S275JR Channel Bar | S355J2 Channel Steel |
|---|---|---|
| Yield Strength (MPa) | 275 | 355 |
| Tensile Strength (MPa) | 410–560 | 470–630 |
| Low Temperature Impact Test | No | Yes (-20°C) |
| Suitable for Cold Weather | Limited | Excellent |
| Chemical Composition | Non-alloy, EN 10025-2 | Non-alloy, EN 10025-2 |
S355J2 is ideal for heavy-load structures and cold climate projects, while S275JR is suitable for standard building structures where low-temperature performance is not required.
Available Types and Stock Sizes
GNEE maintains ready stock of both S355J2 and S275JR channels in multiple types:
- UPN Channels (Tapered Flanges):
- UPN 100×50×6×8.5, UPN 120×55×7×9, UPN 200×75×8.5×11.5
- UPE Channels (Parallel Flanges):
- UPE 80×50×4×7, UPE 120×60×5×8, UPE 140×65×5×9, UPE 220×85×6.5×12
All channels come with EN 10204 3.1 mill certificates, ensuring traceable quality for critical engineering applications.
Applications – How to Choose the Right Channel Steel
Construction Projects:
S275JR: Roof supports, curtain walls, and standard building frameworks
S355J2: Bridges, heavy-load industrial buildings, and large structural frameworks
Mechanical & Industrial Equipment:
Both grades: Machinery frames, industrial racks, and fabricated supports
Transportation & Automotive:
S355J2: Vehicle chassis, ship bulkheads, and low-temperature structural components
Tip: If your project involves cold environments, heavy loads, or critical safety structures, choose S355J2. For standard structural needs, S275JR is cost-effective and widely available.

What is S275JR grade steel?
S275JR grade steel is a readily weldable low carbon manganese steel with good impact resistance. This material is commonly supplied in the untreated or normalised condition. Machinability of this material is similar to that of mild steel.
What is S275JR steel equivalent to?
1 (American Welding Society) permits S275JR as an equivalent to A36 for welding purposes, and they are frequently interchanged in international projects. However, they are not identical: Standards: A36 is governed by ASTM (American), while S275JR follows EN (European), leading to differences in testing requirements.
What type of material is S235JR?
S235JR steel is a low-carbon structural alloy valued for its machinability, strength, and versatility. Perfect for complex components with tight tolerances, it is widely used in CNC machining for mechanical, structural, and industrial applications.
Are A36 and S275JR the same?
Both yield strength and tensile strength of S275JR carbon steel is higher than that of mild steel ASTM A36. So S275JR carbon steel can bear heavier load than mild steel ASTM A36. In other word, mild steel ASTM A36 is not equivalent to S275JR carbon steel.
What is the difference between S235JR and S275JR?
S235JR is used in less demanding applications, such as general construction, lightweight structures, and components where lower strength is sufficient (e.g., beams, columns, and frames). S275JR is preferred for applications requiring higher strength, such as heavier structural components, bridges, or machinery parts.
