20mm Rebar – Deformed Steel Bar (HRB400 / HRB500)
Product Overview
Jingye supplies 20mm rebar, a hot-rolled ribbed deformed bar with a nominal diameter of 20 mm. The nominal mass is 2.47 kg per metre and the nominal cross-sectional area is 314.2 mm2. At the standard 12 m length there are approximately 34 bars to the tonne, or 405 metres to the tonne.
This size is supplied as straight bars in 8 to 12 m lengths. It is normally specified for heavy structural members. All bars carry transverse ribs for mechanical interlock with concrete. Grades are HRB400, HRB400E, HRB500 and HRB500E, and the applicable standards are GB 1499.2, BS 4449, KS D3504, AS/NZS 4671, ASTM A615, SS 560 and the Myanmar, Costa Rican and Colombian standards.
