: Hot-rolled steel continuously rolled and wound into coils, which can later be cut into custom sheet lengths. Note: This standard does not apply to flat steel bars. Standard Dimensions (Thickness & Width)
: Descriptions of methods to verify compliance with the standard, including testing procedures and evaluation criteria.
If you are working with hot-rolled steel in structural, automotive, or general engineering industries—particularly when collaborating with Japanese partners or complying with international standards—you will likely encounter the standard.
If you are dealing with (plate or sheet), JIS G 3193 is the correct dimensional standard. jis g 3193 pdf
JIS standards are revised every 5–10 years. The current valid version as of this writing is .
Civil and structural engineers use the exact masses and section moduli derived from JIS G 3193 to calculate load-bearing capacity. A 2% deviation in flange thickness might lead to a 5–8% deviation in moment of inertia. that feed into safety calculations.
Standards like JIS G 3193 are crucial for several reasons: : Hot-rolled steel continuously rolled and wound into
Applicable only to fixed steel plates and sheets, not coils. Permissible Thickness Tolerances

Width and length tolerances depend heavily on whether the steel is finished with a (mechanically sheared/laser trimmed) or a mill edge (as-rolled from the mill). 1. Width Tolerances
