What thickness or gauge is standard automotive sheetmetal on American vehicles, such as a door skin or fender skin. Decimal Equivalent. The most commonly used sheet metal sizes range from 30 gauge (thinner) to 7 gauge (thicker). Gage. Thanks for any info. Stainless. 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. The customary range gauge of a metal sheet is from a scale of 35 going down to 6. Modern Metal Thickness Measurements The common practice today is to specify the exact thickness of the product in question, thought the gauge may also be listed. NOTES: - Tolerance ranges for gauges 10, 11 and 12 are for widths between 40" and 60". Mechanical Steel Sheet Mechanical Tolerances ... CR - COLD ROLLED Sheet Metal Gage (guage) size chart Carbon Steel Sheets. Lbs/Ft 2. GAUGE TO THICKNESS CHART (Click here for a printable PDF chart) Gauge. H R . For instance, a sheet of 30-gauge standard steel measures 0.012 inches, which is slightly smaller than 30-gauge galvanized steel at 0.0157 inches and slightly larger than 30-gauge aluminum at 0.01 inches. As you can see on the sheet metal gauge chart below, the metal gauge thickness will vary significantly depending on the metal. 5 .2092 ASTM ANSI Mechanical Steel Sheet Mechanical Tolerances. A sheet metal gauge tool is used to measure metal thickness, and show both the gauge number as well as the thickness of the metal in thousandths of an inch. Nevertheless, in some situations sheet metal’s thickness can vary significantly which is then called foil or leaf. Tolerance Range. ASTM-AISI-Thickness-Tolerance-Ranges.pdfDownload .0236 plus .008 is considered to be 24 ga.0236 plus .004 is considered the nominal for 24 ga .0236 + .004 CR . 4 .2242 .2332.2152 . The equivalent thicknesses differ for each gauge size standard, which were developed based on the weight of the sheet for a given material. About product and suppliers: 112 sheet metal thickness range products are offered for sale by suppliers on Alibaba.com A wide variety of sheet metal thickness range options are available to you, There are 13 suppliers who sells sheet metal thickness range on Alibaba.com, mainly located in Asia. Different gauge thickness applies to different metals. Weight. I'm practicing up on my Mig and am trying to determine settings, using ER70-6S and C25.
