The standard provides comprehensive tables specifying the allowable deviation from the nominal dimensions. For instance, for mill-edge steel strips is specifically detailed. In cases of narrower strips (under jis g 3193 pdf
Prevents structural failure from underweight plates; avoids unexpected weight overages.
This standard is essential for manufacturers, quality control professionals, engineers, and anyone involved in specifying, procuring, or working with hot-rolled steel plates, sheets, and strips in the Japanese market and beyond. Its precise tolerances and clear guidelines support the production of high-quality products and facilitate smooth international trade. Valid, fully translated English and Japanese PDF versions
JIS G 3193 is rarely used by itself. It functions as a dimensional baseline that pairs with material property standards. The most common pairs include: Material Standard Description Dimensional Baseline Rolled Steel for General Structure (e.g., SS400) JIS G 3193 JIS G 3106 Rolled Steel for Welded Structure (e.g., SM490) JIS G 3193 JIS G 3131 Commercial Hot-Rolled Mild Steel Coins (e.g., SPHC) JIS G 3193 5. How to Obtain an Official, Legitimate Copy
Flat-rolled steel, generally under 3mm or 6mm in thickness (depending on commercial naming), delivered in cut lengths. If you share with third parties, their policies apply
High-yield steel for welded structures (e.g., SM490).
If you are involved in projects requiring high-quality hot-rolled steel, acquiring the is a necessary investment to ensure your structural components meet international, high-standard requirements.
Features wider tolerances (often +25 mm / -0 mm) because the edges are not trimmed after rolling.
