TECHNICAL FEATURES

► BS4449:2005 GrB500B rebars are produced with low carbon equivalent & Weldable, whereas ASTM A615 Gr60, Gr75, Gr80, QS 600 ISO 6935-2:2007, B500B-R SASO ASTM A615:2015 are Non-Weldable.
► BS4449:2005 GrB500B rebars have High Strength Compared to ASTM A615 Gr60 which reduces steel consumption & congestion in structure, in turn reduces overall cost of project.
► BS4449:2005 GrB500B rebars have High Yield Strength i.e. SOO MPa (Min) compared to ASTM A615 Gr60, without compromising on ductility.
► BS4449:2005 GrBSOOB rebars have better bend performance, due to severe bend & re-bend angle. Rebars conform- ing to BS 1119:2005 Specification, are subjected to Fatigue testing and survive minimum 5 million stress cycles
► QS 600 with Yield Strength>600 MPa: Over the years rebar with yield strength 420MPa, 460MPa, SOOM Pa etc. conforming to BS 4449/ASTM A 615 specifications were available in Qatar/GCC region. Rebar with higher strength i.e.YS>600t1Pa will reduce the steel consumption by around 20 % in construction, which in turn lowers the overall cost of structure. Using high strength rebar QS 600 can also lead to reduction in column size of heavily loaded structure and there is relief from rebar congestion.
