  6. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

  7. Chromate conversion coating - Wikipedia
