what is 12 gauge aluminum sheet?

what is ‘gauge’

If you want to know the specific information of  12 gauge aluminum sheet, firstly，you need to understand what is ‘gauge’.

Gauge is a way of identifying sheet metal thickness.Different gauge numbers indicate different thicknesses, and different metals with the same gauge number have different thicknesses.

16 gauge steel is 1.519mm thick, but 16 gauge aluminium is 1.290mm thick.

How to convert metal gauges to metric units (inches or millimeters)?

Gauges are independent of those metric measurement systems, so if you want to know the specific thickness corresponding to the gauge number of a metal, you need to consult the gauge chart.

The chart below is a complete list of gauge charts for aluminum sheets, we can quickly convert gauges to inches (in), or convert gauges to millimeters (mm).

What is the thickness of 12 gauge aluminum sheet?

gauge–>inch

12 gauge aluminum sheet is 0.0808 inches thick

gauge–>mm

12 gauge aluminum sheet’ thickness  is 2.052 mm( millimeters).

So, the thickness of 12 gauge aluminum sheet and 2mm aluminum sheet is almost the same. This thickness determines its wide application.

Curtain wall panel

Different thicknesses of curtain wall panels are selected according to different architectural decoration requirements. Conventional thicknesses are 1.5mm, 2.0mm, 2.5mm and 3.0mm.

The thickness of aluminum sheet for outdoor building decoration is generally 2.5mm and 3mm; the thickness of 2.0mm can be selected for indoor decoration; the thinnest 1.5mm can be selected for indoor ceiling decoration.

The history of ‘gauge’

What does the gauge of aluminum mean?

The ‘gauge’ system has a long history in metal fabrication.

It likely originated in the UK wire industry before standard and metric measurement systems were widely adopted. At the time, gauge numbers were used to describe the diameter of the wire being drawn.

sheet-metal-gauge

Later, adopted by North American metal manufacturers, it became a popular method of identifying sheet metal thickness, also known as the Manufacturer’s Standard Gauge.

Manufacturer’s standard gauges provide the thickness of standard sheet metal such as steel, aluminum, copper, and stainless steel, and the same gauge number for different metal materials represents different thicknesses.

2 popular gauge standards

1) Brown and Sharpe Gage

Also known as American Wire Gauge (AWG), used for most non-ferrous metals such as aluminum and brass

This standard is more popular, widely used, and has an accepted sheet metal gauge chart

2) Birmingham Gauge

In the UK, Birmingham Gauge (BG) is used for metal in strip and tube, and there are standards for zinc, where higher gauge numbers indicate thicker sheets.

This standard is less applicable

Which is thicker gauge 12 or 14?

From the aluminum gauge table above, we can clearly see that the smaller the gauge number is, the thicker the sheet metal is, and vice versa, the thinner the sheet metal is.

Therefore, the 12-gauge aluminum plate is thicker than the 14-gauge aluminum plate.
