Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner in carbon steel solutions. Our ASTM A36 Carbon Steel Coil with thickness range of 2-12mm and a fixed width of 1500mm is specifically engineered for structural applications. As a newly established yet rapidly growing exporter with annual export value exceeding US$50 million, we combine fresh manufacturing capabilities with global supply chain experience. Each coil is produced under strict ISO9001 quality management system, ensuring consistent mechanical properties and dimensional accuracy for demanding construction projects worldwide.
Our ASTM A36 coils are hot-rolled carbon steel sheets processed into convenient coil form, ideal for further fabrication like cutting, bending, or welding. The material's excellent weldability and moderate strength make it the preferred choice for structural components such as beams, columns, bridges, and industrial buildings. Below we detail the key specifications and advantages that set our product apart.
Key Product Features & Technical Specifications
- Standard Compliance: Fully conforms to ASTM A36 / A36M-19 standard, ensuring minimum yield strength of 250 MPa and tensile strength of 400-550 MPa.
- Dimensional Precision: Thickness tolerance is within ±0.25mm for 2-6mm range and ±0.3mm for 6-12mm range, meeting common structural tolerance requirements.
- Width Uniformity: 1500mm width maintained with ±5mm tolerance, suitable for standard structural profiles.
- Surface Quality: Available in black (as-rolled) or pickled & oiled finish to prevent rust during transit.
- Mechanical Consistency: Controlled rolling process ensures uniform microstructure and reliable mechanical properties coil to coil.
- Edge Condition: Mill edge (as-rolled) or trimmed edge options available upon request.
- Coil Weight: Customizable from 10 tons to 30 tons per coil to optimize your handling and processing efficiency.
