1. fine rolled twisted bar reinforced with General reinforced the main difference is the intensity and chemical composition are not the same.
2. finish rolling thread steel was prestressed steel, higher strength than common rebar. finishing tied rebar yield ratio was 0.9 per cent; and ordinary reinforced yield ratio to 0.6 per cent.
3. elongation rolling rebar reinforcement to around 10%, about common rebar is 30%.
So fine rolled twisted bars a lot containing vertical prestressed beam slab reinforcement and Gao Tieduo tendons while ordinary twisted steel reinforcement can only be used for auxiliary increased bending stiffness.
