Product Introduction
CNB Group supplies high‑precision cold rolled steel coils in both full‑hard and annealed conditions. Our CR steel features a smooth surface and tight thickness tolerance. We offer commercial quality (SPCC), drawing quality (SPCD), and deep drawing quality (SPCE) for applications including automotive bodies, home appliances, office furniture, and tinplate substrate. Bright annealed products keep a shiny, clean surface ideal for decorative use and further coating; black annealed is suitable for stamping and re‑rolling.
