Our alloy carbon steel coils are precision-manufactured from high-quality carbon structural steel with optimized alloy compositions, achieving an exceptional balance of strength and toughness. Featuring smooth surfaces and tight dimensional tolerances (±0.02mm), these coils are available in customized thicknesses (0.3-3.6mm) and widths (600-2000mm). Whether for automotive structural stamping or wear-resistant machinery components, our products deliver outstanding formability and durability, providing reliable material solutions for industrial manufacturing.

Manufactured with advanced tandem cold rolling mills equipped with automatic gauge control (AGC system) and shape regulation technology, the production process integrates a continuous pickling line for complete oxide removal, a high-precision 6-stand cold rolling mill, batch annealing furnaces (HSP & CAP), and a skin pass mill for optimized surface finishing. The fully integrated system ensures exceptional dimensional accuracy and surface quality, delivering thickness control up to ±0.01mm for special orders to meet stringent custom requirements.

The manufacturing process utilizes a fully automated intelligent control system with digital monitoring from raw material pretreatment through continuous rolling and annealing treatment. Equipped with German-engineered 4-high reversible rolling mills and continuous annealing furnaces, we ensure consistent mechanical properties throughout each coil. Online non-destructive testing equipment provides real-time surface defect and microstructure inspection, while precision slitting units guarantee perfect coiling flatness. Our ISO9001-certified production involves 16 quality checkpoints from molten steel to finished products, ensuring uncompromising quality throughout the entire manufacturing process.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
