Sheet Metal Thickness Tolerance

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Sheet metal thickness tolerance.

4 20 2009 11 06 07 am. General information of aluminum sheet thickness. 4 2242 2332 2152. 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.

Thickness measurements are taken at least 3 8 inch in from edge of the strip except that on widths less than 1 inch the tolerances are applicable for measurements at all locatons. Thickness 36 48 60 title. Hr hot rolled cr cold rolled sheet metal gage guage size chart carbon steel sheets. Above tolerances include crown.

Sheet metal guage tolerances. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. The aluminum sheet metal thickness can be divided into four categories. The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.

Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25. Galvanized sheet thickness tolerances thickness in inches weight thickness in millimeters gage min. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. 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.

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. 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.
