JIS G 3112 is the Japanese Industrial Standard specifying requirements for hot-rolled steel bars used as concrete reinforcement. To match this to your program, talk with our team.
What JIS G 3112 Covers
It covers round (plain) and deformed (ribbed) reinforcing bars, defining the grades and mechanical requirements verified by tensile and bend testing.
How the Test Is Run
A rebar sample is pulled to failure with high-force grips, and yield, tensile strength, and elongation are checked against the grade; bend tests confirm ductility.
Why It Matters
Rebar verification underpins reinforced-concrete safety; high-force serrated grips and a bend fixture sized to the bar are essential.
