Metal fabrication tool

Know what’s left on the coil.

Use the MMR Coil Calculator to estimate how much metal remains on a coil or drop coil. Choose steel, aluminum, or copper, select the appropriate gauge, and enter your measurements to calculate the estimated square footage, lineal footage, and total weight.
