Understanding Sheet Metal Gauge
What is Sheet Metal Gauge?
Sheet metal gauge is a measurement used to denote the thickness of sheet metal. There are different standards used for various metals, including the Manufacturers’ Standard Gauge (MSG) for steel and the Brown and Sharpe (B&S) gauge for non-ferrous metals. The gauge number inversely relates to thickness—higher gauge numbers indicate thinner sheets. This can create confusion, especially when mixing materials, as the actual thickness can vary between types of metal.
19 Gauge Steel Sheet Specifications
