The JSA is the primary publisher of JIS standards. Their official online store, the , is the most direct and authoritative source. Here is exactly how to find and purchase the PDF:
Unlike material standards that dictate chemical composition or mechanical strengths (such as JIS G 3101 for general structures or JIS G 3106 for welded structures), JIS G 3193 serves as the universal dimensional framework. It governs the structural uniformity, flatness, and cutting precision of steel products utilized heavily across global manufacturing, shipbuilding, and construction industries.
, adjusted to reflect specific Japanese market transaction practices Rounding Rules : Numerical values within the standard follow JIS Z 8401 , which provides the official guide for rounding numbers Application
Provides the necessary data for inspection reports (mill test certificates). jis g3193 pdf
Maintained by the , JIS G 3193 provides the structural baseline for hot-rolled steel flat products.
Would you like a breakdown of a particular tolerance table from JIS G3193?
If you are sourcing steel from a Japanese mill (Nippon Steel, JFE, or Kobe Steel) to a country using ASTM or EN standards, you must check compatibility. The PDF acts as a quick-reference translation guide. The JSA is the primary publisher of JIS standards

You might wonder why engineers don't just use the physical book. The demand for a digital PDF version stems from three critical workplace needs:
Official copies are copyright-protected and usually require a purchase. You can find them at: It governs the structural uniformity, flatness, and cutting
JIS G3193 aligns closely with the international standard ISO 7452 (Hot-rolled steel plates—Tolerances on dimensions and shape), featuring minor modifications to suit common commercial transaction practices in Japan. 2. Structural Breakdown of a JIS G3193 Document
If you are looking for the , here is a summary of the most common data points found within the standard:
The specifies the dimensions, shape, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips manufactured by Japanese iron and steel producers. Originally established by the Japanese Industrial Standards Committee (JISC) , it provides the physical foundation for standard manufacturing grades like SPHC, SS400, and SM490. Accessing a certified JIS G3193 PDF allows engineers, fabricators, and quality control departments to verify that raw steel shipments match required specifications for thickness, width, length, flatness, and edge conditions. 1. What is JIS G3193?
Thickness must be measured at least 15mm from the edge for cut-edged plates, or 25mm for mill-edged strips Working on an international bid?
