Common Sheet Metal Gauge Chart

Here is another EZ to read chart that shows common sheet metal gauge to decimal equivalent. The chart is easy to read on a tablet or cell phone. Each material, Steel, Galvanized Steel, Stainless, and Aluminum have it's own gauge thickness. The best way to determine thickness is with a micrometer or dial caliper, but if your looking to find out what the decimal equivalent of a particular gauge is this LARGE TEXT chart is an easy way to find out.

Need a low cost dial caliper here is a page full of them at Amazon
