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.
Super thick sheets mm.
Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.
The aluminum sheet metal thickness can be divided into four categories.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
