How To Choose Sheet Metal Thickness

One of the most important decisions when working with sheet metal is deciding what thickness you ll need.

How to choose sheet metal thickness. You can find the gauge to mm inch conversion for sheet metal by the chart below. The thicker the piece of sheet metal the heavier in weight the material is for building. How to choose cut and bend sheet metal thickness. Zinc is measured in millimeter.

In the united states the thickness of the metal is measured as a gauge. But since aluminum is weaker than titanium you d specify a differing decimal thickness for each metal for the same application. Commonly used gauges can range anywhere from 30 to 7. Standard sheet sizes are never the same for sheet metal either.

Parts made from cold rolled sheet must be painted or otherwise protected immediately to prevent surface rust. With custom sheet metal fabrication always note that the higher the number of the gauge the thinner the metal. Based on the product you are planning to develop. These gauge numbers will differ depending on the material.

Cold rolled sheet can be laser cut punched and formed with excellent results. Usually most of the common sheet metal products are made from the sheet thickness 1 2mm for general purposes however cost reduction techniques are applied to even reduce the same if needed. Then as the gauge number increases the sheet metal will become thinner. Use cold rolled sheet crs to get better material strength with a good surface finish.

Some only come in metric. Selecting sheet metal thickness requires familiarity with material gauges. Aluminum is measured in inch. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.

Bending sheet metal can be tricky but with the right tool it s easy. Sheet metal gauge to mm. The selection of sheet metal thickness depends upon the type of use i e. And more consistent metal thickness.
