Gauge size chart for sheet metal. Filter for standard steel, galvanized steel, stainless steel, zinc, or birmingham gage.

Ga. is different from inches, there is no conversion formula. Even when the non-ferrous metal plate and the steel plate are the same Ga., the thickness is actually different. You can find the gauge to mm / inch conversion for sheet metal by the chart below.

2025年1月16日 · Understand the Metal’s Properties: Different metals like stainless steel, aluminum, and galvanized steel have different thicknesses at the same gauge number. Check your chart for these details. Our Sheet Metal Gauge Chart provides a quick reference to all the standard gauges and thicknesses, making it easy to select the right material.

For example, 16 gauge galvanized steel sheet thickness is 1.6129 mm (0.0635 inches); while 18 gauge galvanized steel sheet thickness is 1.3106 mm (0.0516 inches). The steel sheet gauge table below is the equivalent sheet gauge thickness in inches or millimeters. How to Calculate the Weight of Galvanized Sheet?

Galvanized Coating Thicknesses. As you can see from our first chart the galvanized columns are thicker than the regular steel. The process of galvanizing bonds a layer of zinc to the steel. This layer’s thickness can be controlled and the different thicknesses are designated below.
