At present, the main types of the reinforcing steel bars are stress bars, stirrups, erection bars and distribution bars. Conventional steel bars can be classified into four grades according to tensile strength: grade i rebar (grade 235/370); grade ii rebar (grade 335/510); grade iii rebar (370/570) and grade iv rebar (540/835).
The deformed steel bars are mainly divided into 9m, 12m or other fixed sizes which are customized, and are cut off according to needs in the machining process, so that waste materials, namely steel bar heads, are inevitably generated. To some extent, cause losses.
Because the conventional deformed steel bar is inconvenient to bend, the transportation mode is limited, and continuous automatic feeding in automatic construction cannot be realized due to the fact that the deformed steel bar is made of a fixed-length material.
