The standard categorizes bars based on whether they are plain (round) or deformed, and by their yield strength: Civil808.com Minimum Yield Point ( Tensile Strength ( Round (Plain) 380 – 520 Round (Plain) 440 – 600 345 – 440 390 – 510 490 – 625 Standard Specifications Chemical Composition
JIS G3112 is the regulatory benchmark in Japan for hot-rolled steel bars used to reinforce concrete structures. It ensures that the steel provides the necessary tensile strength and ductility to keep buildings and bridges safe, especially in seismically active regions. The standard covers two primary types of bars: jis g3112 pdf
) to prevent brittleness. Mechanically, the bars must undergo rigorous testing for , yield point , and bendability . These tests ensure that the steel can withstand significant stretching and bending during both construction and the lifespan of the building without catastrophic failure. International Alignment and Quality Control The standard categorizes bars based on whether they
💡 If you just need a quick reference for rebar grades (like SD295A, SD345, SD390), many steel mills provide free excerpts – but for full specifications, invest in the official PDF. Mechanically, the bars must undergo rigorous testing for
The symbol stands for "Steel Deformed." The number following "SD" indicates the minimum yield point (yield strength) in Newtons per square millimeter (N/mm²).
Having the official JIS G3112 PDF ensures that you are referring to the exact, unaltered text of the standard, which is legally binding in jurisdictions that mandate Japanese industrial specifications.
The search term "JIS G3112 PDF" is popular because modern construction workflows are digital. Having the standard available as a PDF allows for quick keyword searches, remote access on construction sites via tablets, and easy sharing between site offices and headquarters.
