The numbers of a steel gauge chart typically range between 3-30. Yet those numbers do not indicate a specific dimensional value. Standard gauge sizes were developed based on the weight of the sheet for a given material and the equivalent thicknesses differ for each gauge size.

Jan 24, 2025 · Sheet metal is under ¼ (0.25”) thick. Anything thicker is called a plate. In North America, we measure it in two ways: Gauges (like 14 gauge) – industry standards; Inches (like 0.0747″) – precise measurements; While Europe and Asia primarily use the metric system – millimeters (mm).
