Rebar is the common name for hot rolled ribbed steel bars, mainly used in construction and infrastructure projects. The grade of rebar is usually composed of HRB and the minimum value of its yield point, where H, R and B respectively represent the first letter of the three words Hot-rolled, Ribbed and Bars. According to the national standard, rebar is mainly divided into three grades: HRB335 (two grade rebar), HRB400 (three grade rebar) and HRB500 (four grade rebar), of which three grade and above rebar is the most widely used in engineering.
Rebar is mainly used in reinforced concrete structures of civil engineering projects such as buildings, bridges, and roads, serving as reinforcing bars to enhance the tensile strength and durability of concrete. Its applications also include manufacturing mechanical parts, providing foundation fixing and support in wind power generation, and reinforcing pipelines, tunnels, and other civil engineering projects.
