Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
