#9 Rebar – Deformed Steel Bar (ASTM A615)
Product Overview
Jingye supplies #9 rebar, a hot-rolled ribbed deformed bar with a nominal diameter of 28.7 mm (1.128 inch). The nominal mass is 5.060 kg per metre and the nominal cross-sectional area is 644.6 mm2. At the standard 12 m length there are approximately 16 bars to the tonne, or 198 metres to the tonne.
This size is supplied as straight bars in 8 to 12 m lengths to ASTM A615. It is normally specified for bridges and heavy foundations. All bars carry transverse ribs for mechanical interlock with concrete. Grades are ASTM A615 Gr.40 and Gr.60, and the applicable standards are ASTM A615 Gr.40 and Gr.60.
