steel sheet 2400mmx1200mmx2.38mm Hot Rolled Cold Rolled iron sheet thick carbon
sheet
We offer both Hot Rolled and Cold Rolled carbon steel sheets, two of the most fundamental materials in the metal industry. Whether you need the robust, cost-effective properties of hot-rolled steel for structural applications or the smooth, precise finish of cold-rolled steel for aesthetic and high-tolerance parts, we have you covered. Our standard stock includes popular sizes like 2400mm x 1200mm. At Asia Metal, we are dedicated to meeting your specific needs and offer comprehensive customization of dimensions, thickness, and grade.

| Property | Hot-Rolled Steel (e.g., Q235B) | Cold-Rolled Steel (e.g., SPCC) |
|---|---|---|
| Surface Finish | Slightly rough, scaly surface (mill scale) | Smooth, clean, slightly oily surface |
| Dimensional Tolerance | Less precise, wider tolerance | Highly precise, tight tolerance |
| Yield Strength | ≥ 235 MPa | ≥ 140 MPa |
| Tensile Strength | 370 - 500 MPa | ≥ 270 MPa |
| Applications | Structural parts, frames, general fabrication | Automotive panels, appliances, furniture, precision parts |
The key difference is the processing temperature. Hot-rolled steel is rolled at a high temperature (above 930°C), making it easier to shape and resulting in a rougher, scaly surface with looser tolerances. Cold-rolled steel is processed further at room temperature, which increases its strength and hardness, and produces a smoother, more refined surface with much tighter dimensional tolerances.
It depends on your application. If you need material for structural components, frames, or projects where surface finish and precise dimensions are not critical, Hot-Rolled (HR) steel is a more cost-effective choice. If your project demands a superior surface finish (for painting or coating), tight tolerances, and higher strength, such as for car bodies, appliances, or precision enclosures, then Cold-Rolled (CR) steel is the correct choice.
The 2400mm x 1200mm (often referred to as 8ft x 4ft) is a very common, standard stock size that we keep available for quick dispatch. However, we are not limited to this size. At Asia Metal, we offer full slitting and cutting services to provide steel sheets in any custom length and width you require.
