Cutting-Edge Rolling Mill Facilities – The Backbone of Precision Manufacturing
At the heart of Guangzhou Chengxin’s operational excellence lies its state-of-the-art rolling mill complex, a technological marvel enabling the production of ±0.02 mm tolerance steel coils across hot-rolled, cold-rolled, and coated product lines. This facility represents the pinnacle of precision manufacturing, ensuring that every coil meets the highest standards of quality and consistency. The rolling mill complex is not just a testament to Guangzhou Chengxin's commitment to excellence but also a symbol of China's growing prowess in the Global Steel industry.
Our facility features
- 6-High UCMM Reversing Mills: Equipped with automatic shape control (ASC) and hydraulic gap adjustment (HGA), these mills are capable of achieving 95% thickness uniformity for cold-rolled products. This level of precision ensures that each coil produced meets the stringent quality requirements, making them ideal for a wide range of applications.
- Continuous Galvanizing Line (CGL): This line is capable of processing 300,000 tons/year with zinc coating weights up to 275 g/m². The CGL is designed to provide a high-quality, corrosion-resistant coating to steel coils, making them suitable for use in harsh environments.
Defect Detection
100% coil surface mapping stored in blockchain-enabled traceability database. This innovative approach to data storage ensures that every coil produced can be traced back to its source, providing transparency and accountability in our production process.
Certifications
- CE Marking (EN 15085-2 for welding safety). This certification ensures that our products meet the highest safety standards, giving our customers peace of mind when using our steel coils.
- ISO 50001 energy management compliance, reducing carbon footprint by 28% since 2022. This certification is a testament to our commitment to sustainability and our efforts to reduce our environmental impact.
Applications & Case Studies
Automotive: We are proud to be producing 0.4 mm-thick dual-phase steel (DP780) for EV battery enclosures. Our products are IATF 16949 certified, ensuring that they meet the highest standards of quality and safety in the automotive industry.
Ms.Chen, Chief Engineer, stated:"Investing in new automation ensures we deliver ASTM/JIS/EN-compliant products. Our recent upgrade to AI-driven defect detection systems has slashed surface imperfection rates to <0.2%." This statement highlights our commitment to continuous improvement and our dedication to delivering the highest quality products to our customers.
