Steel Sheet Gauge Tolerances

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Steel sheet gauge tolerances.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Conversion data chart standard gauges chart gauge tolerance chart useful data page. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. 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.
