Advanced Manufacturing Process
Our rigorous production flow ensures that every coil of stainless steel strip conforms strictly to international quality standards.
Raw Material Inspection: Every incoming master coil undergoes spectroscopic chemical analysis and mechanical testing to verify purity and grade compliance.
Precision Cold Rolling: Multi-roll precision mills apply uniform reduction rates to achieve highly consistent thickness profiles across the entire coil length.
Bright Annealing: Heat treatment under a protective atmosphere prevents surface oxidation, restoring excellent elongation and ensuring uniform hardness.
Precision Slitting: Custom-designed slitting lines shear the strips to the exact target width with minimal burr and clean edge conditions.
Quality Control & Verification: Before packaging, we run comprehensive quality checks, measuring:
- Micro-thickness and width tolerances
- Hardness (HV / HRB) and Tensile Strength
- Surface glossiness and roughness
Secure Seaworthy Packaging: Strips are wrapped with moisture-barrier film, anti-rust paper, and desiccants, then securely strapped to heavy-duty wooden pallets or packed in reinforced wooden cases.
