: Rules for measuring how "straight" or "flat" a sheet must be. This is critical for automated fabrication processes like laser cutting or robotic welding.
JIS G 3193 is used at multiple stages of the steel supply chain:

Note: A JIS H-beam is generally slightly heavier and has different flange slopes compared to an equivalent ASTM beam. Always check the PDF before substitution.
Find the row for "12 mm" and column for "Width 2500 mm." The PDF will tell you the allowable deviation (e.g., +0.6 / -0.3 mm). : Rules for measuring how "straight" or "flat"
A standard "JIS G3193 PDF" typically includes detailed tables and rules for the following:

The primary purpose of JIS G3193 is to provide a unified set of requirements for the appearance, shapes, and tolerances of hot-rolled steel. While it covers a wide range of steel products, it specifically .
The JIS G3193 standard is not just a document; it is a contract between the designer, the mill, and the fabricator. Having the correct PDF on hand means avoiding rework, reducing scrap, and guaranteeing that your steel structures stand the test of time.
For sheets and plates supplied in cut lengths, the standard defines the maximum allowable deviation over the nominal length. Typically, the standard only allows positive deviations (meaning the plate can be slightly longer than ordered, but not shorter) to prevent material deficits during fabrication. 4. Flatness and Camber
