Sheet Metal Thickness Tolerance

Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.
Sheet metal thickness tolerance. Actual thickness will vary due to tolerances. Sheet metal is metal formed by an industrial process into thin flat pieces. 4 2242 2332 2152. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal guage tolerances. 4 20 2009 11 06 42 am.
However the range of tolerance on hot rolled sheet is much wider than the range found on cold rolled sheet. Stainless sheet thickness tolerances xls author. General information of aluminum sheet thickness. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Aluminum sheet thickness tolerances xls author. Thicknesses can vary significantly. Stainless sheet thickness tolerances. The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker.
Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. Hr hot rolled cr cold rolled sheet metal gage guage size chart carbon steel sheets. Thickness 36 48 60 title.
Both types of steel sheet have tolerance ranges. The aluminum sheet metal thickness can be divided into four categories. The range of the tolerance minimum thickness to maximum thickness in each gauge range decreases as the sheet material becomes thinner on its nominal or mean thickness. 4 20 2009 11 06 07 am.
