6mm Rebar – Deformed Steel Bar (HRB400 / HRB500)
Product Overview
Jingye supplies 6mm rebar, a hot-rolled ribbed deformed bar with a nominal diameter of 6 mm. The nominal mass is 0.222 kg per metre and the nominal cross-sectional area is 28.3 mm2. This size is rolled as mill coil and sold by weight, so there are approximately 4,505 metres to the tonne; cut into 12 m lengths that is about 375 bars to the tonne.
This size is produced as coiled rebar only, because straight bars start at 12 mm. It is normally specified for welded mesh, light stirrups and binding wire. 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, coiled rebar.

Frequently Asked Questions
- What is the nominal mass of 6mm rebar?
6mm rebar has a nominal mass of 0.222 kg per metre and a nominal cross-sectional area of 28.3 mm2. This size is rolled as mill coil and sold by weight, so there are approximately 4,505 metres to the tonne; cut into 12 m lengths that is about 375 bars to the tonne. The figures follow GB 1499.2 nominal values.
- What length is 6mm rebar supplied in?
Coiled rebar is supplied in mill coils, since this size is not rolled as straight bar.
- Do you supply test certificates for 6mm rebar?
Yes. Every heat is tested for chemical composition, yield strength, tensile strength, elongation and bend performance, and the shipment is released with a mill test certificate.
