There are many types of steel rebars, which can be divided according to different benchmarks. The following is an introduction to the classification of steel rebars under some benchmarks for reference by consumers:

(1) Divide according to mechanical properties. Under this benchmark condition, the reinforcement can be divided into first-grade reinforcement, whose grade is 300/370; second-grade reinforcement, whose grade is 335/510; third-grade reinforcement, whose grade is 370/570; fourth-grade reinforcement, whose grade Level at 540/835.

(2) Divide according to the size of the diameter. Under this benchmark, steel bars can be divided into steel wire (about 3-5mm in diameter), thin steel bars (about 6-10mm in diameter) and thick steel bars (above 22mm in diameter).

(3) Divide according to the production process. Under this benchmark, steel bars can be divided into hot-rolled steel bars, cold-rolled steel bars, cold-drawn steel bars, and heat-treated steel bars.

(4) Divide according to the rolling shape. Under this benchmark, steel bars can be divided into smooth steel bars, steel wires, steel strands, cold-rolled twisted bars, and ribbed bars.

(5) Divide according to the role of steel bars in the structure. Under this benchmark, steel bars can be divided into stressed steel bars (steel bars that bear tension and pressure), erected steel bars (used to fix the steel hoops in the beams to form the steel skeleton inside the beams), and distributed steel bars. (Used in the roof panel or floor, perpendicular to the stressed steel bars, the weight is evenly transmitted to the stressed steel bars, and can also resist deformation) and stirrups (used to bear part of the cable tension stress and It plays the role of fixing the reinforced steel bar, and is mostly used in the interior of house beams and columns). In addition, there are some structural tendons made according to different structural configurations, such as prestressed steel bars, waist bars, and pre-embedded anchor bars, etc.
