What is 12 gage Cold Rolled Steel?

Does anyone know what is 12 gage Cold Rolled Steel meaning? Also, help me to describe it.Thank you so muck ~!Mark Lin


Steel thickness is measured by gages. 16 gage is approximately 1/16th of an inch. The larger the number (say, 24), the thinner the steel. Steel is made from large metal bars (4'x12', about 8 thick) that pass through presses to get thinner and thinner. If the final stages of rolling are done with pressure and not heat, it is cold rolled. It often gets galvanized to prevent rusting. Hope this helps.
It's gauge.
