Aluminum Sheet Metal Gauge Tolerance

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

Aluminum sheet metal gauge tolerance.

Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. 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. 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.
