Understanding JIS G3193: The Standard for Steel Plates, Sheets, and Strips
If you are in the manufacturing or construction industry, you have likely come across the technical specification JIS G3193. This standard, established by the Japanese Industrial Standards (JIS), is the "rulebook" for the dimensions, mass, and permissible variations of hot-rolled steel plates, sheets, and strips.
Whether you are looking for a JIS G3193 PDF to verify tolerances or to ensure your materials meet project specs, What is JIS G3193?
JIS G3193 specifies the shape, dimensions, mass, and tolerances for hot-rolled steel. Unlike other standards that might focus on the chemical composition of the steel (like JIS G3101 for structural steel), G3193 is primarily about the physical geometry of the product. It applies to: Hot-rolled steel plates Hot-rolled steel sheets Hot-rolled steel strips Key Content in the PDF
When you download a JIS G3193 PDF, you are looking for specific data points to ensure your material is "within spec." The document typically includes:
Dimensional Tolerances: This is the heart of the standard. It defines how much the actual thickness, width, and length of a steel plate can deviate from the ordered size.
Flatness: It provides limits on "waviness" or curvature in the steel, which is critical for precision laser cutting or welding.
Squareness: Instructions on how to measure and limit the out-of-squareness of sheets and plates.
Mass Calculation: Formulae for calculating the theoretical weight of the steel based on its dimensions and the standard density of steel ( Why This Standard Matters
Using a standardized reference like JIS G3193 ensures consistency across the global supply chain.
Engineering Precision: If an engineer designs a part assuming a 10mm thickness, they need to know the maximum "minus tolerance" allowed so the part doesn't fail under stress.
Cost Estimation: Accurate mass calculations help procurement teams estimate shipping costs and material pricing.
Quality Control: Receiving departments use these tables to inspect incoming shipments. If a plate is thinner than the G3193 allowance, it can be rightfully rejected. How to Access the Standard
While many websites offer "JIS G3193 PDF" downloads, it is important to ensure you are using the latest revision. Official copies can be purchased through: The Japanese Standards Association (JSA) The ANSI Webstore
Note: Always check if your project requires the most recent version (e.g., the 2019 revision) or if an older version is specified in the contract.
JIS G 3193:2019 is the primary Japanese Industrial Standard that specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips. Searching for "jis g3193 pdf" is the first
Unlike many other JIS standards that define the chemical composition or mechanical properties of a specific metal (like JIS G 3101 for general structures), G 3193 is a dimensional standard. It is used as a companion to multiple product standards to ensure that hot-rolled steel meets strict geometric requirements. 1. Scope and Application
This standard applies to hot-rolled steel products manufactured in Japanese mills, specifically:
Steel Plates: Generally thicker sections used in heavy construction. Steel Sheets: Thinner flat products. Steel Strips: Coiled hot-rolled steel.
Exclusions: It explicitly does not apply to flat steel bars. 2. Core Dimensional Tolerances
The standard provides detailed tables for permissible variations based on the size and shape of the steel.
Thickness Tolerances: Measured at specific distances from the edge—typically at least 25 mm for mill-edged strips and 15 mm for cut-edged plates. The tolerance varies depending on the nominal width and thickness.
Width and Length Tolerances: Variations allowed depend on whether the edges are mill-rolled or cut/trimmed.
Shape and Flatness: The standard defines "lateral warpage" (camber) and flatness limits to ensure the material remains usable for fabrication. 3. Measuring and Calculation
Mass Calculation: JIS G 3193 provides the formula for calculating the theoretical mass of steel based on its nominal dimensions.
Appearance: Specifies that the steel must be free from defects that are detrimental to practical use, although surface imperfections typical of hot-rolling are generally acceptable. 4. Technical Revision History
The standard is periodically reviewed to align with modern manufacturing capabilities. Current Version: JIS G 3193:2019. Superseded Versions: 2008, 2005, and 1990. JIS G 3193-2019 PDF (Dung Sai Thep Tam) - Scribd

While the standard defines physical requirements, it is typically used in conjunction with specific material product standards (like JIS G 3101 for structural steel) to ensure the steel meets both mechanical and dimensional quality benchmarks. Key Technical Sections
The document is structured to cover every physical aspect of hot-rolled products: Dimensions and Expression of Size

JIS G 3193 standard specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips
. It is the primary reference for manufacturing and quality control of flat-rolled steel in Japan and is widely used across the global supply chain 📋 Key Specifications
The standard covers three main categories of flat steel products: Steel Plates and Sheets : Defined by thickness, width, and length Steel Strips : Defined by thickness and width (often supplied in coils) Cut Lengths : Strips that have been cut into specific sheet lengths : This standard specifically does apply to flat bars 📏 Dimensional Tolerances
Tolerances vary based on the thickness and width of the material. Below is a summary of standard thickness tolerances for common dimensions: Thickness Tolerances (Typical Values) Specified Thickness (mm) Width < 1600mm Width 1600–2000mm Width 2000–2500mm Under 1.25 plus or minus 0.16 1.60 to < 2.00 plus or minus 0.19 3.15 to < 4.00 plus or minus 0.24 plus or minus 0.34 plus or minus 0.34 10.0 to < 16.0 plus or minus 0.55 plus or minus 0.65 plus or minus 0.65 Measurement Rules Mill Edges : Thickness must be measured at least from the side edge : Thickness must be measured at least from the side edge 🛠 Comparison & Compliance International Equivalent : JIS G 3193 is a modified version ( ISO 7452:2013

Let’s walk through a practical scenario. You are ordering hot-rolled steel plates of 12 mm thickness, 2,500 mm width, 6,000 mm length from a Japanese mill (like Nippon Steel or JFE).
JIS G 3193 is a Japanese Industrial Standard titled: "Dimensions, mass and permissible variations of hot-rolled steel sections."
Unlike material chemistry standards (like JIS G3101 for SS400 or JIS G3106 for SM490), JIS G3193 does not specify the mechanical properties (tensile strength, yield point) of steel. Instead, it acts as a dimensional rulebook. It establishes the standard sizes, theoretical mass calculations, and allowable tolerance limits for a wide range of hot-rolled steel shapes.
