Sheet Metal Gage Thickness Conversion

So a 20 gauge brake has a maximum bending capacity of 036.

Sheet metal gage thickness conversion.

Sheet metal gauges work opposite to what one might consider the norm. Steel galvanized and aluminum. The smaller the number the thicker the material. For example 20 gauge mild steel is 036 thick.

Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Sheet steel gauge conversion chart the thickness of sheet metals is specified by gauge. Is different from inches there is no conversion formula.

Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different. The gauge number 18 holds no relevance to the actual measurements. Hence 4 gauge material is thicker than 6 gauge material.

Converting sheet metal gauge to thickness in inches. You can find the gauge to mm inch conversion for sheet metal by the chart below. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal gauge to mm.

Sheet metal gauge size chart 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. Gauge ga standard steel thickness. Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5. The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.
