The criteria defined within the JIS G 3193 Document apply uniformly to:
The is a cornerstone Japanese Industrial Standard that specifies the dimensions, shapes, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips. Unlike other structural steel standards that focus on chemical formulas or tensile strengths, JIS G 3193 acts as the foundational metric reference. It is widely used alongside material-grade standards like JIS G 3101 (SS400) . Understanding this technical document is crucial for engineers, fabricators, and steel procurement professionals globally.
Cost estimate: A single-user PDF of JIS G3193 typically ranges from .
When it comes to industrial standards for hot-rolled steel, few are as foundational as JIS G 3193. If you’ve ever searched for “jis g3193 pdf,” you’re likely looking for the official document that defines how steel plates, sheets, and strips should be measured, weighed, and checked for quality before they’re used in bridges, ships, vehicles, or any heavy machinery. This article will walk you through everything you need to know about JIS G 3193—what it covers, who uses it, how it has evolved, and where you can find an official copy. jis g3193 pdf
Thickness is the most critical metric specified in a JIS G3193 PDF. The allowable tolerance varies depending on: The nominal thickness of the plate.
This standard is not applicable to flat bars.
The standard explicitly does not apply to flat steel bars (flat bars) or structural profiles like I-beams and channels, which are governed by other standards such as JIS G3192. The criteria defined within the JIS G 3193
Do not just write "Per JIS G3193." Write: "Thickness tolerances per JIS G3193:2019, Table 2, Class A. Flatness per Table 9, Standard Quality." Then attach the relevant 2 pages of the PDF to the order.
: Specifies permissible variations based on the plate's width and nominal thickness. For example, a plate under 1.25 mm thick with a width under 1600 mm typically has a tolerance of
Practical significance: Engineers and fabricators use JIS G3193 for section selection, structural calculations, and detailing. Contractors rely on its tolerances to plan connections, fits, and welding/bolting operations. Manufacturers follow it to produce consistent profiles and label products.

The 2025 revision was not a minor update. According to the Japanese Standards Association (JSA), the revision was driven by several key factors. Issues with the previous version included the inclusion of manufacturer-buyer contractual agreements within the standard's requirements for strip mass, as well as potential inconsistencies between appearance specifications and actual operational practices.
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.
: Defines standard values for thickness (ranging from 1.4 mm up to over 300 mm), width (600 mm to 3048 mm), and length (1829 mm to over 12000 mm).
