Note: As of late 2025, the standard was updated, with the current iteration frequently referred to as . Scope of the Standard jis g 3193 pdf

In shipbuilding, bridge construction, and high-rise framework, minor structural thinning can compromise structural integrity. JIS G 3193 keeps these deviations within safe structural limits.

If the deviation exceeds the standard, you can reject the material.

, this standard is essential for manufacturers and engineers to ensure consistency and quality in steel products used across various industries, including construction and automotive manufacturing. The current version of this standard is JIS G 3193:2019 , which was establishes based on ISO 7452:2013 JIS G 3193 keeps these deviations within safe

: This could cover requirements for the steelmaking process, chemical composition, deoxidation process, and any special treatments (like heat treatment).

JIS G 3193 is the Japanese Industrial Standard titled "Dimensions, mass, and permissible variations of hot-rolled steel plates, sheets, and strips." Unlike standards that strictly dictate chemical composition or mechanical properties (such as tensile strength), JIS G 3193 is primarily a dimensional standard. It governs the geometric properties of hot-rolled steel, defining the rules by which steel mills produce and deliver their 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. The current version of this standard is JIS

| Dimension Description | Permitted Tolerance | | :--- | :--- | | Depth (Height) of section | ±3.0mm to ±4.0mm depending on size | | Flange width | ±3.0mm to ±5.0mm | | Web thickness | +0.5mm to -0.3mm (varies by nominal thickness) | | Flange thickness | +0.5mm to -0.3mm | | Length | +40mm / 0mm for standard orders |
