ASTM A6 is the American standard for general requirements for rolled steel shapes. Both cover similar ground (dimensions, mass, tolerances), but the numbers differ. An H-beam meeting JIS G 3193 may not automatically meet ASTM A6 without conversion. Always specify the governing standard.
The document is primarily composed of tables that define standard dimensions and the "permissible variations" (tolerances) for those dimensions. 1. Thickness Tolerances
is the Japanese Industrial Standard that defines the dimensions, shape, mass, and permissible variations for hot-rolled steel plates, sheets, and strips.
The standard does not apply to flat bars, and its application is ultimately defined in the relevant product-specific standards that reference JIS G 3193. jis g 3193 pdf

In civil engineering and shipbuilding, a plate that is too thin can compromise structural integrity, while a plate that is too thick adds unnecessary dead weight. Engineers reference the standard to calculate the "minimum guaranteed thickness" of a plate under maximum negative tolerance. Cost and Mass Calculations
JIS G 3193 is more than just a downloadable file; it is a cornerstone of industrial quality control. By strictly defining the dimensions, mass, and tolerances of hot-rolled steel products, it bridges the gap between steel mills and construction sites. Whether used to verify the thickness of a bridge girder or to calculate the shipping weight of a coil of steel, JIS G 3193 provides the necessary framework for precision and reliability. As long as hot-rolled steel remains a primary building block of modern civilization, the detailed specifications contained within the pages of JIS G 3193 will remain indispensable.
For steel strips and cut lengths, the standard thickness is generally . Standard Width Always specify the governing standard
The JIS G 3193 standard has a long history, having been first established on July 30, 1954. It has undergone several revisions since then to keep pace with technological advancements and changes in the industry.
