: Flat-rolled products typically below 3.0 mm thick, supplied as cut lengths.
It specifies the standard dimensions, tolerances, and permissible variations for hot-rolled steel plates and sheets produced in Japan. It applies to general structural steels, automotive, shipbuilding, and pressure vessel grades unless otherwise specified in individual product standards (e.g., JIS G 3101, JIS G 3106, JIS G 3116).
For professionals in the structural steel, manufacturing, and construction industries, adhering to precise standards is non-negotiable. is the Japanese Industrial Standard that defines the dimensions, mass (weight), and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips .
The standard is formally titled "Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips," and is published by the Japanese Standards Association (JSA) under the authority of the Japanese Industrial Standards Committee (JISC). As the primary specification for hot-rolled flat steel products, JIS G 3193 serves as the foundational document that ensures quality, interoperability, and safety across manufacturing and construction sectors. jis g 3193 pdf
The JIS G 3193 standard regulates the production profile of dimensional boundaries across three fundamental structural shapes:
Tolerances differ for "mill edges" (untrimmed) and "cut edges" (trimmed/resheared).
The demand for the PDF version reflects the fast-paced nature of modern construction and manufacturing. Engineers require instant access to tolerance tables to verify designs or inspect incoming materials. The digital availability of the standard has streamlined supply chains, allowing for immediate dispute resolution regarding whether a delivered shipment falls within the agreed-upon "JIS" specifications.
JIS G 3193 is referenced alongside several primary material specifications: JIS G 3193:2019 Hot Rolled Steel Standards - Scribd Once you have legally obtained the PDF, integrate
Plates/sheets are expressed by thickness, width, and length (mm). Strips use thickness and width (mm).
Thickness variation is a critical factor in structural calculations. JIS G 3193 establishes varying tolerance brackets depending on the of the material. Broadly, as the plate or sheet gets wider, the mill requires a wider tolerance margin.
Most infrastructure projects across Asia (and many that follow Asian standards globally) explicitly require compliance with JIS. If you are supplying steel products to a project in Japan, the Philippines, Thailand, Vietnam, or Indonesia, your material certifications must reference JIS G 3193 tolerances. Without the PDF for reference, you cannot legally certify that your steel meets the required dimensional specs.
Outlines the maximum permissible waviness of a plate when laid on a flat surface. Thicker, narrower plates have stricter flatness limits than thin, wide sheets. As the primary specification for hot-rolled flat steel

Only if the mill declares so. Some specialty plates (e.g., wear-resistant or clad plates) may be supplied under different dimensional agreements.
