Sheet metal manufacturing and services the following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases.
Awg sheet metal thickness.
Cold and hot rolled steel 16 gauge 14 gauge 1 8 and 1 4.
The sheet metal gauges are neither standard nor metric the numbers are independent of measurement systems and do not mean actually measured value.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Commonly used metals for manufacturing at our shop are.
The brown and sharpe gage also known as the american wire gage awg is used for most non ferrous metals such as aluminum and brass.
16 ga crs is 2 5 pounds per square foot.
In addition the same gauge number for different materials presents different thickness for example 37 gauge stainless steel is 0 0066 inches thick while 37 gauge aluminum is 0 0045 inches thick.
Below you will find a chart for metal thicknesses and weights.
The gauge number 18 holds no relevance to the actual measurements.
Gauge to thickness chart.
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.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
For other materials such as aluminum and brass the thicknesses will be different.
The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel.
There are several different gauge systems used today with specific gauge designations used for specific metal types.
For sheet metal products.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
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.
This is known as the manufacturers standard gage for sheet steel.
