What are the Gauges?

The gauge is used to specify the thickness of the sheet metal. The gauge is neither standard nor metric, and its value has nothing to do with those measuring systems.

The sheet metal thickness gauge for steel is based on a weight of 41.82 pounds per square foot per inch of thickness. This is called the steel plate manufacturer’s standard gauge.

FAQ

What are the gauges of sheet metal?

The larger the specification number, the thinner the metal. The commonly used steel sheet metal sheet ranges from size 35 to about 3.

16 gauge thickness in mm

standard steel: 1.367

GALVANIZED steel: 1.161

ALUMINUM:1.29

Stainless Steel: 1.588

18 gauge thickness in mm

standard steel: 1.214

GALVANIZED steel: 1.31

ALUMINUM:1.024

Stainless Steel: 1.27

What gauge metal is thicker 14 or 16?

14 gauge is thicker, Let’s take galvanized steel as an example: 14gauge = 1.993mm , 16guge = 1.161.

Which 22 or 24 gauge?

22 gauge is thicker.  22 gauge STEEL is 0.0299 in, 24 gauge STEEL is 0.0239 in.

Which is thicker 20 or 30 gauge?

20 gauge is thicker.  20 gauge STEEL is 0.912mm, 30 gauge STEEL is 0.305.

Is 29 gauge metal roof good?

The metal roof of 29 gauge is relatively thin. If you live in an area with strong winds and bad weather, we recommend using a thicker 22 gauge metal roof.

What is thicker 7 gauge or 10 gauge?

7 gauge is thicker. 7 gauge STEEL is 4.554mm,  10 gauge STEEL is 3.416mm.

Which is thicker 22 gauge or 26 gauge?

22 gauge is thicker. 22 gauge STEEL is 0.0299 in,  26 gauge STEEL is 0.0179 in.

What is thicker 16 gauge or 20 gauge?

16 gauge is thicker. 16 gauge STEEL is 0.0598 in,  20 gauge STEEL is 0.0359 in.

What gauge are metal roofs?

The metal thickness of the roof ranges from 22 gauge (thickest) to 32 gauge (thinest).
