As a leading manufacturer based in Liaocheng, Shandong, Hemaokang Steel (Shandong) Co., Ltd. specializes in producing high-quality cold rolled mild steel sheets designed specifically for automotive panel applications. Our Mild Steel Sheet 1.2mm x 1250mm x 2500mm Cold Rolled is engineered to meet the rigorous demands of the automotive industry, offering exceptional dimensional accuracy, superior surface finish, and consistent mechanical properties. Despite our recent establishment in 2025, we leverage decades of industry expertise and a state-of-the-art production facility to deliver products that compete globally. With an annual export value ranging from US$50 Million to US$100 Million and a dedicated team of 51–100 professionals, we ensure every sheet meets ISO9001 certified quality standards.
Product Features & Technical Specifications
- Precision Cold Rolling Process – Our sheets undergo multiple cold rolling passes to achieve a tight thickness tolerance of ±0.05mm and excellent flatness, ensuring seamless forming and welding for automotive body panels.
- Superior Surface Quality – The cold-rolled surface is free of scale and pits, with a smooth finish (Ra ≤ 1.2μm) that reduces the need for additional grinding or coating preparation, saving time and cost in downstream processes.
- Excellent Formability – Made from low-carbon mild steel (typical grades DC01 or SPCC), the sheet offers high ductility and elongation (≥28%), enabling deep drawing and complex stamping without cracking – ideal for door panels, hoods, and fenders.
- Consistent Mechanical Properties – Stress-relieved during annealing, the material provides uniform hardness (HRB 45–60) and tensile strength (270–410 MPa), guaranteeing repeatable results in automated production lines.
- Anti-Rust Protection – Each sheet is oiled and interleaved with protective paper to prevent corrosion during transit and storage, maintaining its pristine condition until use.
