The 2025 revision is notable for addressing several critical points. The JSA noted that the previous 2019 version had issues where certain clauses were inconsistent with operational realities. The 2025 revision makes key changes that include:
Do not just look at nominal dimensions. Scroll to the "Permissible variations" tables and apply the allowed plus/minus to your inspection criteria.
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) jis g 3193 pdf
When dealing with steel coils (strip), the calculation ignores length and uses total coil mass, which must be tracked via automated mill scales. Why Is This Standard Crucial for Quality Assurance?
The standard is formally titled "Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips," and is published by the Japanese Standards Association (JSA) under the authority of the Japanese Industrial Standards Committee (JISC). As the primary specification for hot-rolled flat steel products, JIS G 3193 serves as the foundational document that ensures quality, interoperability, and safety across manufacturing and construction sectors.

: Standard nominal thicknesses, widths, and lengths for various steel products.
The standard specifies exactly where to measure thickness—usually not less than 15 mm or 25 mm from the edge, depending on whether it is a cut or mill edge.
