Metric Sheet Steel Thickness Tolerance

Cold rolled steel sheets dc01 electro galvanized steel sheets dc01 ze and hot dip galvanized steel sheets dx51d.

Metric sheet steel thickness tolerance.

Sheet metal guage tolerances. Cold rolled carbon steel sheet metal is used in automotive panels trailer siding roofing and fuel tanks. Cold rolled sheet dc01 en 10131 table 1 thickness tolerance 6mm to 8mm 05mm 8mm to 1mm 06mm 1mm to 1 2mm 07mm 1 2mm to 1 6mm 09mm. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.

Low carbon steel rods and discs also known as mild steel low carbon steel is easy to machine form and weld. Equal to less than 1000 1000 thru 1300 1300 thru 2100. 4mm 28mm 28mm 4mm. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

The gauge number 18 holds no relevance to the actual measurements. 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. Thickness is measured along the longitudinal edges of the plate at least 3 8inches but not more than 3 inches from the edge. With a thickness that s precision ground to a tight tolerance these bars are sometimes called flat stock.

O1 tool steel sheets and bars also known as flat stock these precision ground sheets and bars are held to a tight thickness tolerance. 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. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
