HOT ROLLED Deformed Steel Bar for Construction

Rebar is steel for reinforced concrete and prestressed reinforced concrete with a round cross-section, sometimes square with rounded corners. It includes bright round bars, ribbed bars and twisted bars.

Reinforced concrete reinforcing bars are straight bars or coils of steel for reinforced concrete reinforcement, and their shape is divided into two kinds of light round bars and deformed bars, and the delivery status is straight bars and coils.

Light round bars are actually small round bars and discs of ordinary low carbon steel. Deformed bars are bars with ribs on the surface, usually with 2 longitudinal ribs and evenly distributed horizontal ribs along the length. The shape of the cross-rib is spiral, herringbone, crescent-shaped 3 kinds. The number of millimeters of nominal diameter is used. The nominal diameter of the deformed reinforcement is equivalent to the nominal diameter of the light round bar with equal cross section. The nominal diameters of steel bars are 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi. reinforcing bars are mainly subjected to tensile stresses in concrete. Deformed steel bars have a greater bonding capacity with concrete due to the ribs, and thus can better withstand the external forces. Reinforcing steel is widely used in various building structures. Especially for large, heavy, light thin-walled and high-rise building structures.
