Maintained by the , JIS G 3193 provides the structural baseline for hot-rolled steel flat products.
For strips and coils, the PDF details how much the side edge can curve laterally over a given length (e.g., 5 mm per 10 meters).
Unlike material chemistry standards (like JIS G3101 for SS400 or JIS G3106 for SM490), JIS G3193 does not specify the mechanical properties (tensile strength, yield point) of steel. Instead, it acts as a . It establishes the standard sizes, theoretical mass calculations, and allowable tolerance limits for a wide range of hot-rolled steel shapes.
The specifies the dimensions, shape, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips manufactured by Japanese iron and steel producers. Originally established by the Japanese Industrial Standards Committee (JISC) , it provides the physical foundation for standard manufacturing grades like SPHC, SS400, and SM490. Accessing a certified JIS G3193 PDF allows engineers, fabricators, and quality control departments to verify that raw steel shipments match required specifications for thickness, width, length, flatness, and edge conditions. 1. What is JIS G3193? jis g3193 pdf
The standard covers steel products with a thickness of 1.6 mm or more and a width of 500 mm or more. The steel products covered by JIS G3193 pdf are used for various applications, such as:
If your design calls for a 200x200x8x12 H-beam (JIS standard) but only ASTM A992 is available locally, use the PDF to compare the sectional modulus (Zx) and radius of gyration (rx). The tolerances differ; the JIS beam will have tighter straightness requirements.

The standard is a copyrighted document published by the Japanese Standards Association (JSA).
Varies based on width; for example, plates under 1600mm wide have tighter +/- tolerances than wider products Measurement Zones: Instead, it acts as a

Because JIS G3193 only covers dimensions and tolerances, it is always paired with material quality standards. Common pairings include:
Open your PDF. Ensure it says "JIS G 3193:2019" on the cover page. If it says 2008, stop. You are using an outdated tolerance map.
