Cold Reduced steel (CR)
Cold Reduced steel (CR) is a strip mill steel product made from cold rolling a hot rolled pickled product at room temperature. After cold rolling, it is annealed (continuous or batch process) and skin passed to produce a formable product with a high quality surface finish.
Here at GNEE STEEL, we stock and process DC01 mild steel (often referred to as CR4), in varying thicknesses from 0.9mm up to 3mm. Each sheet is de-coiled and flattened to strict tolerances , ensuring consistent quality and flatness, every time.
What is DC01 steel?
Cold-rolled steel plays an essential role in industries such as automotive production, electrical manufacturing, home appliances, HVAC systems, and metal fabrication. Among the most commonly used grades, DC01 steel stand out due to their versatility and excellent surface quality.

DC01 Steel Chemical Composition
The low carbon content of DC01 steel (≤0.12%) gives it excellent formability and surface quality, which means it is both strong and flexible when cold-formed and can easily adapt to various processing techniques. Whether it is bending, stamping, or forming complex shapes, DC01 steel can maintain stable quality performance, making your production smoother.
| Element | Content (%) |
| Carbon, C | ≤ 0.12 |
| Manganese, Mn | ≤ 0.60 |
| Phosphorus, P | ≤ 0.045 |
| Sulfur, S | ≤ 0.045 |
| Silicon, Si | ≤ 0.03 |
| Nitrogen, N | ≤ 0.008 |
| Aluminum, Al | ≤ 0.02 |
| Copper, Cu | ≤ 0.20 |
