JIS SS400 / EN S235JR / GB Q235B Carbon Structural Steel Bar / Rod




Common carbon structural steel, also known as ordinary carbon steel. The limitations on carbon, performance range, phosphorus, sulfur and other residual elements are relatively wide. As a result, there are more impurities and the price is moderate, mostly used in places where performance requirements are not high. The carbon content is mostly below 0.30%, manganese content is less than 0.80%, and the strength is low, but the plasticity, toughness and cold deformation properties are good. Except in a few cases, it is usually used directly without heat treatment to manufacture strip steel, profiled steel, steel plate, etc.


SS400 round bar is the most common yet widely used grade as a structural steel. SS400 grade is also known as JIS3101 having low carbon content. This kind of steel is widely used for manufacturing industrial applications and equipment.




It has a wide range of uses and a large amount of usage. It is mainly used in railway, bridge, all kinds of construction projects,and to produce all kinds of metal components bearing static loads, mechanical parts and welding parts which are less important and need no heat treatment.

These round bars are available in seamless, welded and fabricated types and in different shapes and sizes as per the demand and requirement of customers. At the time of manufacturing these bars, national and global specifications are added to the material. Superior and excellent quality of the material is used and is well inspected so that it can perform its best in the respective areas of working. In addition to it, advanced technologies and latest tools are used for creating an accurate size and length of bars.


Each and every material used for manufacturing is tested and inspected by our experts so that no damage is caused when the product is ready and used for further manufacturing purpose. These bars are known best of its admirable features like long service life, durability, workability, formability, weldability, tensile strength, excellent corrosion resistance. All these features make round bars even more demanding among industrial applications.


To know whether the manufactured product is of good quality or not and will it perform best at a high and elevated temperature or not, numerous tests are done. The entire testing and inspection process takes place under the strict regulation and observation of experts and inspection agencies. When all the tests are done, we offer different test certificates proving product quality and durability.
