Sheet metal guage tolerances during the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
Gauge range for 16 gauge steel sheets.
Gauge decimal equivalent hot rolled p o tolerance range cold rolled tolerance range lbs.
0 7 mm 0 8mm and 1 5 mm.
Tolerance ranges for all other gauges are for widths between 32 and 60.
Gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.

Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing sponsored links wire gauge is a measure for the size of a wire either in diameter or in cross sectional area.
Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh 41 82 0 1345 5 625 pounds per square foot.
26 gauge 24 gauge 20 gauge 18 gauge 16 gauge 14 gauge 1 8 and 1 4.
For 18 ga crs the weight is 2 0 pounds per square foot and for 20 ga crs the weight is 1 5 pounds per square foot.
16 ga crs is 2 5 pounds per square foot.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
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.

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.
