Sheet Metal Gauge Chart

Sheet metal gauge chart: We supply Full Sheets, Part Sheets, Cut to Size and CNC shape cutting, we can take DXF and most common file types.

We can TIG weld Copper, Brass, Bronze and Stainless, and MIG weld Aluminium, Corten and Mild Steel. Zinc and Pewter are soldered. Information on zinc gauge (zg) is also given on this page.

It is possible to TIG weld zinc but the fumes are quite toxic so care must be exercised.

Understanding Zinc Gauge Chart

It’s important to note that zinc sheet has a unique gauge system that differs from traditional SWG measurement methods used for materials like steel and aluminum. Known as Zinc Gauge (ZG), the system operates inversely compared to other sheet metal gauges—the thickness actually increases as the gauge number goes up.

While zinc gauge isn’t commonly referenced in most sheet metal fabrication practices, familiarity with it is advantageous, especially if you encounter gauges instead of thicknesses in specifications.

For your reference, some common zinc sheet sizes and their corresponding gauges include:

  • 13zg = 0.8mm
  • 14zg = 0.9mm
  • 15zg = 1.0mm
  • 16zg/17zg = 1.2mm
  • 19zg = 1.5mm

If you’d like to explore this topic further, additional information can be found on Wikipedia regarding zinc gauge.
