Heavy-gauge flat steel usually thicker than 3mm.
The PDF includes comprehensive tables for permissible variations:
The Japanese Standards Association provides the most accurate and up-to-date versions, including the English version, JIS G 3193 : 2019. Standards.ie : Provides instant downloads for this standard. jis g3193 pdf
All dimensions, including thickness, width, and length, must be expressed in millimeters (mm) . Key Specifications and Tolerances
Steel plate mass is calculated using the standard density of 7.85 g/cm³ (or 7.85 kg/mm·m²). The standard mass (kg/m²) is simply: . For a given plate, the mass is then calculated as: mass = length (m) × width (m) × thickness (mm) × 7.85 . The standard also provides tables of standard masses for various thicknesses, widths, and lengths. For reference, the mass per square meter for a 12 mm thick plate is 94.2 kg/m². Heavy-gauge flat steel usually thicker than 3mm
At its core, JIS G3193 defines the (tolerances) for hot rolled steel products. It ensures that the steel you order meets specific physical requirements, which is critical for precision engineering and structural integrity.
The Japanese Standards Association (JSA) provides the authoritative version. All dimensions, including thickness, width, and length, must
In industrial procurement, it’s crucial to know the differences between national standards. Here’s how JIS G 3193 stacks up against other global specifications:
If you are in the manufacturing or construction industry, you have likely come across the technical specification . 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.
In steel procurement, material is often bought and sold by theoretical weight rather than actual scale weight. JIS G3193 provides the baseline calculation standard.
