Steel Bar Processing Machine, In the current steel standards for reinforced concrete, three main strength grades are specified for hot-rolled construction steel bars: 300 MPa, 400 MPa, and 500 MPa. For processing and distribution, most companies primarily handle the following nine types of steel bars:
- HPB215 high-strength wire
- HPB300 high-strength wire
- Q300 hot-rolled round steel
- HRB400(E)/500(E) coil
- HRB400(E)/500(E)/600(E) threaded steel
- CRB550 cold-rolled ribbed steel bars
To meet the diverse requirements of reinforced concrete projects across various sectors, new specialized processing and distribution enterprises must be equipped with at least 11 types of mechanical processing equipment. Below is an overview of the main machinery and their processing ranges:
