JIS G 3112:2020 PDF Download

The JIS G 3112:2020 standard sets out the requirements for round and deformed steel bars that are manufactured by hot rolling and intended for use as reinforcement in concrete. It should be noted that this standard does not cover rerolled steel bars for concrete reinforcement as specified in JIS G 3117.

In terms of international correspondence, this standard aligns with ISO 6935-1:2007, which specifies plain bars for the reinforcement of concrete, and ISO 6935-2:2019, which focuses on ribbed bars. The degree of correspondence between the JIS standard and these international standards is considered to be moderate.

It's worth highlighting that the term "steel bars" in this context includes both individual bars and those supplied in coil form. This standard provides important guidelines and criteria to ensure the quality and suitability of steel bars for reinforcing concrete structures.
