Note: Actual product dimensions and coil weight may vary according to mill production tolerance and customer requirements.

 

 

For transformer manufacturers and electrical equipment producers, accurate calculation of CRGO coil weight is important for material planning, transportation arrangement and production cost estimation.

The theoretical weight of grain oriented electrical steel coils can be calculated based on coil dimensions and material density.

 

CRGO Coil Weight Calculation Formula

A commonly used calculation method is:

• Coil Weight (kg) = (OD² - ID²) × Width × 0.00000765

Where:

• OD = Outer diameter of coil (mm)
• ID = Inner diameter of coil (mm)
• Width = Coil width (mm)
• 0.00000765 = Conversion factor based on electrical steel density (approximately 7.65 g/cm³)

 

For export purchasing, the final net weight may vary slightly due to:

• Actual coil dimensions;
• Thickness tolerance;
• Processing loss during slitting;
• Packaging weight calculation method.

Professional suppliers normally provide actual coil weight information on packing lists and mill documentation.
