While working with sheet metal, gauge values may be used to denote a specific thickness. At the end, it depends on what material it is being used for. Each gauge value does not have an exact measurement value in its own, but will have a thickness value when referred to a specific material.

For example, a 19 Gauge for stainless steel will have a thickness of .0438″, while a 19 Gauge for aluminum will be .0359″. When determining the thickness of a metal sheet using the gauge system, a gauge chart should be used. In the chart below, we will list down the gauge values for stainless steel sheets.
