Used for building, strengthening piers, walls, load-bearing beams, columns, foundations and other structures to improve the stability and safety of the project.
HRB is the steel bar grade, H, R, B are hot rolled (Hotrolled), Ribbed (Ribbed), Bars
HRB400 (20MnSiV, 20MnSiNb, 20MnTi), the standard yield strength of the steel bar is 400MPa, and the design value is 360MPa. Diameter 6 ~ 50mm, elastic modulus 200GPa.
Low carbon steel rebar The surface of low carbon steel is flat and the shape is round. They come in a variety of sizes from 6 mm to 50 mm. They are used in concrete for special purposes, such as dowel for expansion joints, where rods must slide in metal or paper sleeves, for contraction joints for roads and runways, and for column spirals. They are easy to cut and bend without damage. For structural buildings, such as Bridges and other heavy structures, the use of mild steel rods is not recommended because there is not a great deal of adhesion, slip and strength between concrete and steel. Deformed steel bars have ribs, lugs and indentation on the surface of deformed steel bars, which reduces the main problems faced by low carbon steel due to slip and achieves good bonding between concrete and steel bars. Higher tensile properties compared to other rebar. These bars range in diameter from 6 mm to 50 mm.
Deformed bars are commonly known as hot-rolled ribbed bars. It belongs to the skeleton of small steel and rebar mainly used for building components. In use, it is required to have certain mechanical strength, bending deformation properties and process welding properties. The raw material billet for the production of rebar is carbon structural steel or low alloy structural steel which has been melted by sedation, and the finished rebar is delivered in hot rolled form, normalizing or hot rolled state.
