This S275JR mild steel channel is a C-shaped structural section manufactured in accordance with EN 10025-2 standards. It is widely used in structural and general engineering applications where good strength, weldability, and machinability are required.
The channel offers excellent weldability and machinability, making it suitable for fabrication, cutting, and welding processes. While its formability is limited, it performs reliably in load-bearing structures.
S275JR mild steel channel
The material provides good corrosion resistance under normal service conditions and is typically supplied in bare (uncoated) condition, allowing for further surface treatment such as painting or galvanizing if required.
With precise dimensions and consistent mechanical properties, this S275JR channel section is commonly applied in construction frames, supports, brackets, and steel structures.

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.
