Rebar
Rebar is the common name for hot rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed ofHRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words Hotrolled, Ribbed.and Bars respectively. Hot-rolled ribbed steel bars are divided into three grades: Grade II HRB335 (the old grade is 20MnSi), Grade IIlHRB400 (the old grades are 20MnSiV,20MnSiNb, 20Mnti), and Grade IV HRB500.
HRB500 Rebar
Rebar is widely used in building, bridge, road and other civil engineering construction. Large to highways, railways, Bridges, culverts, tunnels, flood control, DAMS and other public facilities, small to the foundation of housing construction, beams, columns, walls, boards.
Deformed Steel Rebar
Rebar is usually used in reinforced concrete, the effect of its stripes is to increase the friction force, make rebar and concrete bite together, form one,under the action of external force will not produce twitching phenomenon, improve the strength of concrete.
