Common Aluminum Sheet Metal Gauges

Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities.

Common aluminum sheet metal gauges.

Aluminum is a common metal used for both industrial and non industrial applications. General information of aluminum sheet thickness. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example. However it is not recommended for sheet metal work because it tends to crack on the outside radii once it passes its yield and therefore requires a much larger radii to be able to bend properly.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. This is known as the manufacturers standard gage for sheet steel. The aluminum sheet metal thickness can be divided into four categories. To help this blog will explain the gauge system and features a sheet metal gauge chart.

Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. In most of the world sheet metal thickness is consistently specified in millimeters. In most cases it can be difficult to choose the correct aluminum grade for your intended application.

Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. 3003 aluminum sheet has a smooth semi shiny finish and is popular for many applications including. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 3003 h14 aluminum sheet astm b209 qq a 250 2 excellent weldability and formability with good corrosion resistance makes 3003 aluminum sheet a popular and economical choice.

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. Mill finish not polished. Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades. The larger the gauge number the thinner the metal.

If your project does not have any physical or structural demands and the aesthetics are not important then almost any aluminum grade will do the job. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Aluminum is a general purpose alloy commonly used in extrusions and is also available in sheet metal. Fuel tanks food chemical handling trailer siding roofing etc.

For other materials such as aluminum and brass the thicknesses will be different.
