Reference this chart for part sizing in all our materials.
Before there was a way to use physical measurements, gauge size charts were used to describe the thickness of sheet metal materials. However, gauge thickness is dependent on the density of the material, which means that different materials use different gauge charts.
At SendCutSend we provide all of our material options in imperial and metric systems so there’s no confusion on what size material you’re ordering. However, it’s still valuable to understand the different gauge sizes.
Check out the video below to learn more about gauge thickness and reference the following gauge charts to see what materials we have in stock.
