Deformed Bar (Rebar)
D10 – D50
The standard structural reinforcing bar for concrete construction, rolled in thirteen diameters from D10 to D50 and certified to Vietnamese, Japanese and American standards. Every bar carries a rolled-in mill mark and diameter index, so material can be traced from the site back to the cast.
- Thirteen diameters, D10 through D50
- Nine grades across three standards
- Standard 11.7 m length; bundles run 2.6 – 2.8 t
- Mill test certificate issued per heat number
- TCVN 1651-2:2018
- JIS G 3112:2020
- ASTM A615M-20
