Always ensure you access the of the PDF through official channels to guarantee your data is accurate and your project remains compliant.
Generally ranges from under 1.60 mm up to over 300 mm.
Ultimate Guide to JIS G 3193: Dimensions, Masses, and Tolerances for Hot-Rolled Steel
: JIS G 3193 does not apply to flat bars or steel sections, which are covered by separate standards like JIS G 3194 and JIS G 3192.
Specific tolerances apply to resheared or fine-cut plates compared to normal cutting methods. jis g 3193 pdf
JIS G 3193 has been revised multiple times (e.g., 1990, 2003, 2008, 2019). If your PDF is from 1990, the permissible variations may be obsolete. Always download the (check JSA for current year).
Thickness must be measured at least 25 mm from the side edge.
In this guide, we break down what JIS G 3193 covers, why it is critical for construction and manufacturing, and how you can access the official documentation.
For the most accurate, up-to-date information, it is advised to check the JSA website for the latest 2025 revision. Always ensure you access the of the PDF
JIS G 3193 PDF: Dimensions, Weight, and Tolerances for Hot-Rolled Steel
: Defined in standardized tables to match industrial requirements. Length : Specified for cut lengths of sheets and plates. 3. Permissible Variations (Tolerances)
| Resource | Pros | Cons | | :--- | :--- | :--- | | (e.g., Nippon Steel, JFE Steel) | Free, easy to read, widely used | Only covers their products, not all tolerances | | Engineering handbooks (e.g., Machinery's Handbook) | Summarized values | Not legally binding for compliance | | CAD block libraries | Digitally pre-modeled sections | Often no tolerance data, just nominal sizes |
: Detailed specifications on dimensions (thickness, width, length), mass, and acceptable deviations from the specified measurements. Specific tolerances apply to resheared or fine-cut plates
The standard ensures that the materials delivered by the manufacturer meet precise dimensional tolerances necessary for automated manufacturing and structural integrity. Key Aspects of JIS G 3193 1. Dimensional Tolerances (Thickness, Width, Length)
If you need the official, full-text technical standard, you should acquire it from authorized sources to ensure accuracy.
For compliance and accuracy, always purchase the official JIS G 3193 PDF from the Japanese Standards Association (JSA) Web Store or an authorized distributor. Avoid "free" versions which are often outdated and incomplete.
It is important to distinguish between "unofficial" mirrors and the authoritative source. While you may find scanned copies on engineering forums, these are often:
