Cold Rolled Steel Coil DC01 DC02 DC03 SPCC
Manufacturing Process
- Raw Material Preparation: Quality-checked hot rolled coil or plate serves as the primary raw material
- Pre-treatment: Heating and cleaning to remove surface oxides and dirt for smoother surface preparation
- Cold Rolling: Multi-pass rolling through 4-6 stands to achieve required thickness and width, including embossing, trimming, and polishing
- Pickling: Oxide and rust scale removal to enhance surface flatness and finish
- Oiling: Surface protection against oxidation and corrosion, reducing friction during handling
- Cutting: Precision cutting to specified lengths and widths for diverse industry applications
- Packaging: Final packaging with comprehensive labeling including specifications, batch numbers, and production dates
