Aluminum sheet metal gauge tolerance.

The aluminum sheet metal thickness can be divided into four categories. Monroe nor any of its employees shall be held liable for any improper or incorrect use of the information described and or contained herein and assumes no responsibility for anyone s use of the information. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. 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. Super thick sheets mm. 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. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.
