Pdf - Jis G 3193

Do not just look at nominal dimensions. Scroll to the "Permissible variations" tables and apply the allowed plus/minus to your inspection criteria.

The standard specifies the dimensions, mass, shape, and permissible dimensional tolerances for hot-rolled steel plates, sheets, and strips . Governed by the Japanese Industrial Standards (JIS) committee, this manufacturing benchmark ensures absolute consistency and structural integrity across heavy manufacturing, infrastructure, and automotive industries.

It outlines standard thicknesses (ranging from 1.4 mm to over 50 mm), standard widths (up to 3048 mm), and standard lengths (up to 12,192 mm). Dimensional Tolerances:

It is vital to understand that JIS G 3193 does not exist in a vacuum. While it dictates shape and size , it is almost always used in conjunction with material standards such as JIS G 3101 (General Structural Steel) or JIS G 3106 (Rolled Steel for Welded Structures). jis g 3193 pdf

Find your nominal size (e.g., "200 x 100"). Read the row: height, flange width, web thickness, corner radii.

When a manufacturer certifies a steel plate to a structural standard like JIS G 3101 SS400, they will simultaneously reference to confirm that the physical dimensions of the plate fall within legal, safe, and commercial tolerances. 2. Key Dimensional Tolerances Specified in JIS G 3193

If you are searching for the PDF download, you likely need to verify one of three critical factors:

JIS standards are established by the Japanese Standards Association (JSA) to standardize products, ensure safety, and facilitate trade. JIS G 3193 specifically could pertain to steel plates used in various applications, including construction, shipbuilding, and manufacturing of pressure vessels. Do not just look at nominal dimensions

Once you have legally obtained the PDF, integrate it effectively:

The Jis G 3193 standard offers several benefits to manufacturers, users, and consumers of steel products, including:

is a critical Japanese Industrial Standard that defines the dimensions, shape, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips . Established in 1954 and most recently updated in 2025 , this standard ensures consistency and quality for flat-rolled steel products used across construction, automotive, and industrial manufacturing. Scope and Application

The standard outlines dimensional configurations for three distinct hot-rolled product categories: While it dictates shape and size , it

A crucial section of the JIS G 3193 PDF details how to calculate the theoretical weight of steel. In global logistics and trade, steel is bought and sold by metric tonnage. Because physical weighing can vary by scale calibration, contracts often use based on standard dimensions.

Measures maximum deviation from a straight line along the longitudinal edge.

Lists other standards required for the application of JIS G 3193.

If your PDF lacks these references, you are missing context.

This standard is essential for manufacturers, quality control professionals, engineers, and anyone involved in specifying, procuring, or working with hot-rolled steel plates, sheets, and strips in the Japanese market and beyond. Its precise tolerances and clear guidelines support the production of high-quality products and facilitate smooth international trade.
