, JIS G 3193 includes specific technical modifications to reflect Japanese transaction practices . For those used to standards, it’s comparable to specifications like for general tolerances of structural steel Key Data Points in the Standard: Thickness Tolerances:
Flatness is measured on a flat surface plate. The deviation is calculated as the difference between the highest point of the convex side and the actual thickness of the steel. 📥 Where to Find the PDF jis g3193 pdf

If your design calls for a 200x200x8x12 H-beam (JIS standard) but only ASTM A992 is available locally, use the PDF to compare the sectional modulus (Zx) and radius of gyration (rx). The tolerances differ; the JIS beam will have tighter straightness requirements.
The standard, titled "Dimensions, mass and permissible variations of hot rolled steel plates, sheets and strips," is a technical specification published by the Japanese Standards Association (JSA) . It serves as the primary reference for ensuring dimensional accuracy and tolerance compliance in the Japanese steel industry. Overview of JIS G3193
