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.
For plates up to 10 in.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
