In the ever-evolving world of construction, manufacturing, and heavy industry—where progress is driven by innovation and efficiency—the demand for materials that offer durability, formability, and cost-efficiency remains unwavering. Among the myriad of available options, the A36/Q235/S235JR carbon steel coil stands out as a globally recognized mild steel coil solution, celebrated for its excellent mechanical performance, ease of processing, and broad applicability across a range of industries.
This family of low carbon steel coils, including A36 carbon steel coil, Q235 carbon steel coil, and S235JR carbon steel coil, is widely used in civil engineering, machinery fabrication, automotive parts production, agricultural equipment manufacturing, and general industrial applications. Its balanced properties of strength, ductility, and weldability make it a trusted material for builders and fabricators worldwide.
A36, Q235, and S235JR are standard-grade carbon steels classified under different national standards. A36 belongs to ASTM (USA), Q235 is the GB standard (China), and S235JR falls under the EN standard (Europe). Despite the regional variations, these grades share nearly identical core characteristics and are all considered hot rolled carbon steel coils suitable for structural applications.
These carbon steel coils are primarily composed of iron with a carbon content of about 0.2–0.29%, offering moderate strength and good toughness. Additional elements such as silicon, manganese, and trace amounts of sulfur and phosphorus further enhance the coil’s mechanical integrity and welding performance. These properties make it an ideal structural steel coil for both load-bearing and forming applications.
With tensile strength ranging from 400 to 550 MPa and yield strength starting at ≥235 MPa, these low carbon steel coils offer the required resilience for load-bearing components and structural frameworks. They maintain good elongation (≥20%) for shaping and deformation processes.
Thanks to their low carbon composition, these coils support MIG, TIG, and arc welding processes without the need for preheating. The material is also ideal for bending, stamping, laser cutting, punching, and rolling—making it a fabricator-friendly mild steel coil option.
Available in custom thicknesses from 0.1mm to 200mm and widths up to 2500mm, our hot rolled carbon steel coils and cold rolled carbon steel coils are suitable for both light and heavy-duty industrial uses.
International Standard Compliance
