Material Weight

Material Weight

In order to estimate the cost of material it is essential that you know the weight of different material gauges and types of material.   Below you will find a list of some common weights dealing with the metal industry and metal fabrication.  One of the key factors is knowing the weight factor because its the same for all gauges of like material.

Weight Factor – Weight Per Cubic Inch of Material

The weight factor is calculated by the following formula

(Weight) / (Width * Length * Thickness)

The nice thing about knowing the weight factor is you can easily determine the weight of any size of metal.  For example, 16 Gage sheet steel has a weight factor of 0.29032.  If you have a 36×96 inch sheet of 20 Gage Sheet Steel, the weight would be 0.0375*36*96*0.29032 resulting in 60 Lbs.  Knowing the weight factor of sheet steel you now can calculate all the weights very easily.
