Sheet Metal Size Conversion

Steel galvanized and aluminum.

Sheet metal size conversion.

Cold and hot rolled steel 16 gauge 14 gauge 1 8 and 1 4. Tap and drill sizes. Sheet metal gauge to inch. Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5.

Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different. Print this page. For example 20 gauge mild steel is 036 thick. 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. Aluminum 0 025 0 032 0 040 0 050 0 063 0 080 1 8 0 125 and 1 4 0 25. Weight per square foot of material is also provided. Print this page.

So a 20 gauge brake has a maximum bending capacity of 036. There are several different gauge systems used today with specific gauge designations used for specific metal types. Decimal nearest fractional 4 112 7 64 6 138 9 64 8 164 11 64 10. Galvanized steel 24 gauge 20 gauge 18 gauge and 16 gauge.

Table 1 sheet metal sizes including gauge and weight per square foot. The maximum capacity of a sheet metal brake or shear is based on the total thickness gauge of mild steel at its full length.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Decimal nearest fractional 4 112 7 64 6 138 9 64 8. Table 1 below summarizes the most common sheet metal sizes for aluminum standard sheet steel stainless steel and galvanized steel.

Copper 48 oz 24 oz 20 oz and 16 oz. 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. Us sheet metal screw diameters. Or you can download the sheet metal gauge size chart pdf.
