Sheet Metal Material Standards

Standard specification for steel sheet metallic coated by the hot dip process and prepainted by the coil coating process for exterior exposed building products.

Sheet metal material standards.

A792 a792m 10 2015 standard specification for steel sheet 55 aluminum zinc alloy coated by the hot dip process. Sheet metal is the next in line. But for harder materials e g. Sheet metal thickness ranges from 0 024 in.

The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm. Enclosure sheet thickness depends on material properties product size weight constraints and loads acting on it. Because sheet metal parts are manufactured from a single sheet of metal the part must maintain uniform wall thickness. Steel grades standards by country.

A875 a875m 13. International organization for standardization iso ts 4949 2003. Japanese steel grades. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

Aisi sae steel grades standard british standards. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. For alloys in general including steel unified numbering system uns of astm international and the society of automotive engineers sae. The minimum distance between two counterbores is eight times the material thickness.

The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. Structural simulation or manual calculations are recommended to calculate required sheet thickness. Standard specification for steel sheet as cold reduced for conversion to annealed cold rolled steel sheet and hot dip metallic coated steel sheet astm a1093 a1093m standard specification for electrolytic plasma treatment processing of conductive materials. European standards en 10027.

The thin sheet metal is easy to form while still providing great strength. Recommended inside bend radius for sheet metal parts should be equal to material thickness. Sheet metal materials are available in standard sheet thickness. 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.

Anything above that is a metal plate. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger counterbores. American steel grades.

At a relatively cheap price it makes a great fit for most engineering purposes. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
