Sheet Metal Gauge Size Conversion

Typically the even number gauges are used more frequently.

Sheet metal gauge size conversion.

The maximum capacity of a sheet metal brake or shear is based on the total thickness gauge of mild steel at its full length. 8 gauge 4 115 mm. The comparison of different unit systems is shown in the table below. The larger the number of gauge is the smaller the diameter is.

Converting sheet metal gauge numbers to millimeters is as simple as following the chart below. So a 20 gauge brake has a maximum bending capacity of 036. For a more comprehensive gauge chart you can check out our sheet metal gauge chart here. For example 20 gauge mild steel is 036 thick.

8 gauge 4 191 mm aluminum brass copper. This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel. 8 gauge 4 176 mm stainless steel. It is also used to indicate thickness after promotion.

There is no conversion formula due to the difference between ga. The gauge number 18 holds no relevance to the actual measurements. Sheet metal gauge thickness chart. For different materials of steel the same gauge will also correspond to different mm.

Steel galvanized and aluminum. Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5.
