Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.

Aluminum sheet metal gauge tolerance.

History of the gauge system the gauge system has long history in metal fabrication. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075. The aluminum sheet metal thickness can be divided into four categories. Super thick sheets mm.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
