JIS G 3112 — Steel Bars for Concrete Reinforcement

← Back to all standards

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.
