Introduction to Rebar

Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction. 

The shape of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of nominal diameter.

The nominal diameter of ribbed steel bars is equivalent to the nominal diameter of plain round steel bars with equal cross-sections. 

The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. Ribbed steel bars mainly bear tensile stress in concrete. 

Due to the effect of ribs, ribbed steel bars have greater bonding ability with concrete, so they can better withstand the effects of external forces. 

Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

Rebar is widely used in civil engineering construction such as houses, bridges, and roads.

From large public facilities such as highways, railways, bridges, culverts, tunnels, flood control, dams, to small foundations, beams, columns, 

walls and slabs of building structures, rebar is an indispensable structural material.
