Aluminum sheet metal gauge tolerances.

Gauge nominal in mm max in mm min in mm 10. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

Steel sheet metal tolerances. An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less. General information of aluminum sheet thickness. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. The aluminum sheet metal thickness can be divided into four categories. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. 0 1345 3 42 0 1405 3 57 0 1285 3 26 11.

For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075.
