How to Use This Table
- Find your flat sheet width → Choose the total width of your sheet before rolling.
- Select your overlap → If welding or joining is needed, account for overlap.
- Read the estimated cylinder diameter → This is the expected diameter of the rolled sheet.
How is Cylinder Diameter Calculated?
The formula used: Cylinder Diameter=Flat Sheet Width−Overlapπ\text{Cylinder Diameter} = \frac{\text{Flat Sheet Width} – \text{Overlap}}{\pi}Cylinder Diameter=πFlat Sheet Width−Overlap​
Where:
- Flat Sheet Width = The total sheet width before rolling.
- Overlap = The amount of material lost due to welding or joining.
- π\piπ (Pi) ≈ 3.1416.
Key Takeaways
- Larger flat sheets create larger diameter cylinders.
- More overlap reduces the final cylinder size.
- Used in metalworking, fabrication, ductwork, piping, and more.
- Works for steel, aluminum, plastic, and other rollable materials.
