JIS G 3193:2019 (and its 2025 successor) was developed based on (Hot-rolled steel plates—Tolerances on dimensions and shape). While it is modified to better reflect Japanese practical trading practices (noted as 'MOD' in the standard), it largely aligns with international standards.
The 2019 revision introduced changes regarding the definition of "strip" and updated tolerance tables to align more closely with international standards (like ISO 4995). Using an outdated PDF could lead to non-compliant fabrication or rejected material shipments.
To prevent "wavy" plates that interfere with automated robotic welding and plasma cutting tables, establishes clear metrics for flatness and lateral warpage:

It does not stand alone; instead, it is referenced by specific steel grades to define physical geometry:
JIS G 3193 applies to a wide range of hot-rolled steel products, but it does apply to hot-rolled steel flat bars. It is often referenced in conjunction with material-specific standards such as: JIS G 3101 (General Structural Steel)

dictate the chemical composition or mechanical strength of the steel (those are covered by material-specific standards like JIS G 3101 for structural steel or JIS G 3131
You're looking for a PDF related to JIS G 3193!
Specific measurement positions are mandated to ensure uniformity. For example, for cut-edged plates, thickness is measured no less than 15 mm from the edge.
Free PDF sharing sites often host outdated or incomplete versions of the standard, which can lead to critical compliance errors in professional manufacturing environments.
These revisions demonstrate the Japanese Standards Association's commitment to ensuring that JIS G 3193 remains relevant, precise, and aligned with the needs of the modern steel industry. Using an outdated PDF could lead to non-compliant
When a factory produces hot-rolled steel under standards like JIS G 3101 (SS400 structural steel) or JIS G 3106 (SM400 welding steel), they use JIS G 3193 to determine the allowed physical deviations in thickness, width, length, and flatness. Scope of Coverage
The demand for the PDF version reflects the fast-paced nature of modern construction and manufacturing. Engineers require instant access to tolerance tables to verify designs or inspect incoming materials. The digital availability of the standard has streamlined supply chains, allowing for immediate dispute resolution regarding whether a delivered shipment falls within the agreed-upon "JIS" specifications.
: Continuous rolled steel wound in coils, providing high-efficiency feed material for automated stampings.
The standard specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips . The most recent major revision is JIS G 3193:2019 , which replaced the 2008 version and aligns closely with the international standard ISO 7452:2013 . Core Content of JIS G 3193
