Rebar

Professional Introduction：Rebar is commonly known as hot-rolled ribbed steel bar.

Ordinary hot-rolled steel bars are designated by the initials HRB followed by the minimum yield point value of the grade. H, R, and B represent the first letters of Hot-rolled, Ribbed, and Bars, respectively. Hot-rolled ribbed steel bars are classified into three grades: Grade HRB335 (old grade 20MnSi), Grade HRB400 (old grades including 20MnSiV, 20MnSiNb, 20Mnti), and Grade HRB500.

For seismic structures with higher requirements, the applicable grades are designated by adding E to the existing grade (e.g., HRB400E, HRBF400E).

Specifications: The standard recommended nominal diameters for rebar are 6, 8, 10, 12, 16, 20, 25, 32, 40, and 50mm, with typical cut-to-length sizes of 9m and 12m.

Standard Numbers: GB1499.2-2007 (Steel for the Reinforcement of Concrete – Part 2: Hot Rolled Ribbed Steel Bars); GB1499.2-2007/XG1-2009 (Amendment No. 1 to GB1499.2-2007); GB/T 2101-2008 (General Requirements for Inspection, Packing, Marking, and Certification of Steel Sections); GB1499.1~GB1499.3 (Steel for the Reinforcement of Concrete); JIS G 3112-87 (1998) (Steel Bars for Reinforced Concrete); JIS G 3191-66 (1994) (Shapes, Dimensions, Masses, and Tolerances of Hot-rolled Steel Bars and Coiled Bars); BS 4449-97 (Hot Rolled Steel Bars for the Reinforcement of Concrete).

Applications: Rebar is widely used in civil engineering projects such as houses, bridges, and roads. From public facilities like highways, railways, bridges, culverts, tunnels, flood control, and dams to the foundations, beams, columns, walls, and slabs of buildings, rebar is an indispensable structural material.
