Carbon Steel Bar
Carbon steel bar is widely used in machinery, construction, automotive, manufacturing, and general engineering. It offers a practical combination of strength, machinability, weldability, and cost, making it suitable for both structural use and the production of machined components.
We supply carbon steel bars in different shapes, including round bar, square bar, flat bar, and hexagonal bar. A range of carbon steel grades is available to meet different requirements for strength, hardness, wear resistance, and machining performance.
Our carbon steel bars can be supplied in hot rolled, cold drawn, forged, peeled, polished, and other conditions. Available dimensions cover various diameters, widths, thicknesses, and lengths. Cutting and other processing services can also be provided according to drawings or specific project requirements.
Carbon steel bars are commonly used to manufacture shafts, pins, gears, bolts, fasteners, rods, machine parts, automotive components, tools, and structural parts. They are also suitable for further machining, heat treatment, welding, and fabrication.
We can supply carbon steel bars according to ASTM, AISI, SAE, EN, DIN, JIS, and other commonly used standards. Different grades, sizes, tolerances, surface conditions, and delivery requirements can be arranged based on the application.

Carbon Steel Bar Application
FAQ
What carbon steel bar grades and shapes do you supply?
We regularly supply carbon steel bars in ASTM A36, AISI 1018, 1020, and 1045, EN S235JR/S355JR, JIS SS400, and GB Q235/Q355. Available shapes include round, square, flat, and hexagonal bars. Other grades and specifications are also available on request.
What is the difference between hot rolled and cold drawn carbon steel bars?
Hot rolled carbon steel bars are commonly used for general fabrication, construction, and structural applications. Cold drawn bars offer a smoother surface and tighter dimensional tolerances, making them suitable for machined parts, shafts, and precision components.
What carbon steel bar sizes are available?
We supply a wide range of standard sizes for carbon steel round bars, square bars, flat bars, and hexagonal bars. Custom diameters, widths, thicknesses, and lengths can also be arranged depending on the grade and quantity.
Can carbon steel bars be cut to custom lengths?
Yes. We provide cut-to-length service for carbon steel bars. Send us your required lengths, cutting list, or drawings, and we can prepare the material before shipment.
Do you provide MTC for carbon steel bars?
Yes. A Mill Test Certificate (MTC) can be provided with the order. Third-party inspection, such as SGS or BV, can also be arranged before shipment if required.
How are carbon steel bars packed for export?
Carbon steel bars are usually packed in bundles with steel straps for shipment. Special export packing can also be arranged based on bar size, order quantity, and shipping requirements.
What information do you need for a quote?
Please send us the grade, shape, size, length, and quantity, along with your destination port and any cutting, inspection, or packing requirements. We’ll get back to you with a quote.
