Legitimate sources (paid, but legal):
For rectangular sheets, the standard defines how much the corners may deviate from a perfect 90-degree angle. This is usually expressed as a ratio (e.g., less than 0.5% of the diagonal length). jis g3193 pdf
For a limited time after a revision, "draft" versions may be available for public comment, but these are rarely the final PDF. Do not rely on these for commercial manufacturing.
Note: A JIS H-beam is generally slightly heavier and has different flange slopes compared to an equivalent ASTM beam. Always check the PDF before substitution.
If you’re looking for the PDF for an ongoing project, always check the . As of 2026, the valid version is JIS G 3193:2025 . Older editions (2008, 2019) are interesting for historical reference but should not be used for new orders unless specifically agreed. The official JIS G 3193 PDF is the only document that guarantees you are seeing the legally correct values, as confirmed by the Japanese government and the Japanese Industrial Standards Committee. specifies the: : Individual sheet pieces uncoiled and
The standard covers hot-rolled steel products divided generally into three categories based on thickness and form:
The structure of the standard is logical and easy to navigate:
In steel procurement, material is often bought and sold by theoretical weight rather than actual scale weight. JIS G3193 provides the baseline calculation standard. This is usually expressed as a ratio (e
: Instructions on how to measure and limit the out-of-squareness of sheets and plates.
I once consulted for a structural steel fabricator who downloaded a "free" JIS G3193 PDF from an unknown blog. They used thickness tolerances from the 1990 version (which allowed +0.8 mm tolerance on 9mm plate). The 2019 version allowed only +0.5 mm.
Using the mass tables in the PDF, you can precisely calculate freight costs. If a JIS beam weighs 56.2 kg/m, and you need 1,000 meters, you require exactly 56.2 tons—not the nominal weight.
