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. Astm a480hot rolled sheet coil thickness tolerance.

Let s say that 11 gauge has a nominal thickness of 0 1196 inch from memory. Sheet metal guage tolerances. It applies to the following specifications that describe carbon steel structural steel and high strength low alloy steel hsla furnished as hot rolled sheet and cold rolled sheet. The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.

And astma653 a653m 94 standard specification for sheet steel zinc coat galvanized or zinc iron alloy coated galvanized by the hot dip process. 0236 plus 008 is considered to be 24 ga. Theoretical nominal weight tnw weight based upon the lineal footage using nominal weight per foot. The tolerance is only 0 014 inch for sheet narrower than 40 inches.

These measurements are based on astm a924 924m 94 standard specification for general requirements for sheet steel metallic coated by the hot dip process formerly astma525. 0236 004 0276.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. 1 1 this specification covers the general requirements for steel sheet in coils and cut lengths. Hr hot rolled cr cold rolled sheet metal gage guage size chart carbon steel sheets. The permitted thickness would be from 0 1196 to 0 1356 as this thickness permits 0 016 inch tolerance for sheets over 40 inch wide.

Actual weight actual scale weight of the coil. Astm a240 a480 steel sheet sthickness tolerance. Astm s steel standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of the different types of steels which are primarily used in the production of mechanical components industrial parts and construction elements as well as other accessories related to them. Table a2 8 permitted variations in flatness of cold rolled wide coil processed product as cut lengths.

Astm ansi mechanical steel sheet mechanical tolerances. Tolerance below apply to the following alloys.
