The official PDF of the standard can be obtained by purchasing it directly from authorized standards distributors. The price for the 20-page Japanese version of JIS G 3193:2025 is , while the 19-page English version costs 14,300 JPY (approx. $95 USD) .
Think of the broader JIS G 3101 standard as the "birth certificate" for general structural steel (like the ubiquitous SS400), defining its chemical composition and mechanical properties. Following that analogy, —a companion standard that sets the dimensional rules for how that steel must be physically delivered. This Japanese Industrial Standard applies specifically to flat products created through the hot-rolling process. It covers a wide array of items:
When sourcing hot-rolled steel plates, sheets, or strips, particularly for projects involving Japanese materials, the standard is crucial. It defines the mandatory requirements for dimensions, mass, and permissible variations (tolerances) for these materials. jis g3193 pdf
Ensures that purchased steel meets authorized dimension standards.
Understanding the content of JIS G 3193 can save a fabricator from using the wrong thickness tolerance and discovering that a 12‑mm plate is actually 11.8 mm, possibly jeopardizing a structural connection. The official PDF of the standard can be
| Length (mm) | Tolerance (mm) | |---|---| | 600 ≤ ℓ < 4,000 | +20 / 0 | | 4,000 ≤ ℓ < 6,000 | +30 / 0 | | 6,000 ≤ ℓ < 8,000 | +40 / 0 | | 8,000 ≤ ℓ < 10,000 | +50 / 0 | | 10,000 ≤ ℓ < 15,000 | +75 / 0 | | 15,000 ≤ ℓ < 20,000 | +100 / 0 | | 20,000 ≤ ℓ | +0.5% / 0 |
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.
