First established in the 1960s and revised periodically (with major revisions in 1990, 2008, and 2019), this standard specifies the general tolerances and requirements for flat steel products. Without JIS G3193, a steel plate ordered from a Japanese mill might not fit into a fabricated structure designed in another country.
If you can tell me you are using (e.g., SPHC, SS400) or what thickness you need to know, I can find the precise tolerances for you.

Width tolerances dictate how much a plate or sheet can deviate from its ordered width. JIS G3193 categorizes these based on the edge type:
The standard defines the maximum allowable deviation from a flat plane for plates of different thicknesses and widths. For example, thinner and wider plates are allowed slightly more deviation.
| Length (mm) | Tolerance (mm) | |---|---| | 600 ≤ ℓ < 4,000 | +20 / 0 | | 4,000 ≤ ℓ < 6,000 | +30 / 0 | | 6,000 ≤ ℓ < 8,000 | +40 / 0 | | 8,000 ≤ ℓ < 10,000 | +50 / 0 | | 10,000 ≤ ℓ < 15,000 | +75 / 0 | | 15,000 ≤ ℓ < 20,000 | +100 / 0 | | 20,000 ≤ ℓ | +0.5% / 0 | First established in the 1960s and revised periodically
Would you like a comparison between JIS G 3193 and a similar standard (e.g., ASTM A6 or EN 10034), or help interpreting a specific tolerance table from it?
In steel procurement, material is often bought and sold by theoretical weight rather than actual scale weight. JIS G3193 provides the baseline calculation standard.
The JIS G3193 pdf standard offers several advantages to manufacturers, suppliers, and users of steel products. Some of the benefits include: JIS G3193 categorizes these based on the edge
Specifies the maximum allowable deviation from a flat surface when the plate is laid on a level floor. This is crucial for CNC laser cutting and automated welding.
: Defines the theoretical mass of steel plates and sheets, generally expressed in kilograms. Obtaining the JIS G 3193 PDF
Find the row for "12 mm" and column for "Width 2500 mm." The PDF will tell you the allowable deviation (e.g., +0.6 / -0.3 mm).
If you need to verify specific tolerances for a project, consulting the 2019 edition of JIS G 3193 on JSA Webdesk is recommended.
For width, tolerances depend on whether the steel has a "mill edge" (as-rolled edge) or a "cut edge" (sheared or trimmed edge). Cut-edge steel has tighter, more precise tolerances, as specified in detail within the standard.
