    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.

    In tinner's snips this means the handles are extra long. The compound-action bulldog-pattern, also known as a notch snips, has the ability to cut up to 16 gauge cold rolled sheet metal or multiple layers of sheet metal up to 0.062 in (1.6 mm) thick. Some snips have replaceable blades for when the blade becomes worn out.

  7. Rolling (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Rolling_(metalworking)

    [20] For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.
