What Are Hot Rolled and Cold Rolled Steel Sheets?
Hot Rolled Steel Sheets are processed at high temperatures, making them easier to shape and form. They are ideal for applications where precise dimensions aren’t critical but strength is essential. On the other hand, Cold Rolled Steel Sheets are processed at room temperature, resulting in a smoother finish and tighter tolerances, perfect for applications requiring exact dimensions and superior surface quality. Explore our range of steel sheets.
Key Differences Between Hot Rolled and Cold Rolled Steel Sheets
- Manufacturing Process
- Hot Rolled Steel Sheets: Rolled at temperatures above 1700°F, allowing for easier shaping and forming.
- Cold Rolled Steel Sheets: Rolled at room temperature after being cooled from the hot rolling process, providing a smoother finish.
- Surface Finish
- Hot Rolled: Rougher, scaled surface with slight imperfections.
- Cold Rolled: Smooth, polished surface with tighter tolerances.
- Dimensional Accuracy
- Hot Rolled: Less precise, suitable for structural components.
- Cold Rolled: More accurate dimensions, ideal for aesthetic applications.
- Strength and Hardness
- Hot Rolled: Softer, more ductile, suitable for welding.
- Cold Rolled: Harder and stronger due to strain hardening.
