Product Overview

JIS G3112 is Japanese industrial standard for hot‑rolled deformed steel reinforcing bar, covering SD295, SD345, SD390, SD490 grades. SD295 and SD345 are low‑to‑medium yield grades for ordinary residential building; SD390 for medium‑load infrastructure; SD490 is high‑strength rebar widely used for bridge, pier, heavy‑duty foundation in Japan and Southeast‑Asia countries adopting JIS norm.

Ribbed deformed surface ensures reliable bonding force with concrete. Diameter range Φ6‑50mm. Standard length 9m /12m, custom‑cut length from 3‑18m. Hot‑rolled black finish or epoxy anti‑corrosion coating optional for coastal environment.
