The density of steel varies depending on the alloy components but generally ranges from 7750 to 8050 kg m3484 and 503 lb cubic feet or 775 to 805 g cm3448 and 465 oz cubic inches. Tendon high strength low allow steel typically used for instance in pre-stressed concrete elements this steel grade is likely to contain more virgin steel Rebar steel basic steel used for concrete reinforcement.
