| Production Process | Rebar is a steel bar with ribbed surface, also known as ribbed reinforcement, usually with 2 longitudinal ribs
and a transverse rib evenly distributed along the length direction.
The shape of transverse rib is spiral shape,
herringbone shape and crescent shape. In terms of millimeters of nominal diameter.
The nominal diameter of ribbed reinforcement is equal to the nominal diameter of the light-round reinforcement with the same cross-section.
The nominal diameter of the steel bar is 8-50 mm, and the recommended diameter is
8, 12, 16, 20, 25, 32 and 40 mm.Ribbed bars mainly bear tensile stress in concrete.
The ribbed steel bar can bear the action of external force better because of the effect of ribbed and concrete.
Ribbed bars are widely used in various building structures, especially large, heavy, light thin-walled and tall buildings. |

| Application | Rebar is widely used in building, bridge, road and other civil engineering construction. From highway, railway,
bridge, culvert, tunnel, flood control, dam and other public facilities, to the building foundation, beams,
columns, walls, plates, screw steel are indispensable structural materials. With the deepening of China's urbanization,
the demand for rebar is strong for infrastructure construction and the booming development of real estate. |
