These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
Sheet metal gauges work opposite to what one might consider the norm.
In an earlier article we took a look at the standard gauges for steel sheet.
Copper sheeting comes in thicknesses ranging from very thin copper foil to thick copper plate.
Below is a quick guide to help you determine which thickness best suits the needs of your project.
