Steel wire rod (iron rod) rebar & thread bar for building
Rebar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross-section is round, sometimes square with rounded corners. Including round steel bars, ribbed steel bars, and twisted steel bars.
Reinforcing steel bars for reinforced concrete refer to straight or coil-shaped steel used for the reinforcement of reinforced concrete. Its shape is divided into two types: smooth steel bars and deformed steel bars, and the delivery status is straight and coiled.
Light round steel bars are actually small round bars and coils of ordinary low-carbon steel. Deformed steel bars are steel bars with ribs on the surface, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of the nominal diameter. The nominal diameter of deformed steel bars is equivalent to the nominal diameter of smooth round steel bars with equal cross-sections.
The nominal diameter of the steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Rebars mainly bear tensile stress in concrete. Due to the action of ribs, deformed steel bars have greater bonding capacity with concrete, so they can better withstand external forces. Steel bars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.
Hot-rolled, cold-rolled, and cold-drawn steel bars, as well as heat-treated steel bars made of grade IV steel bars after heat treatment, have higher strength than the former.
Yield point (fy)
When the stress of the steel bar exceeds the yield point, the tensile force does not increase but the deformation increases significantly. When a large residual deformation will occur, the tensile force value at this time is divided by the cross-sectional area of the steel bar to obtain the tensile force per unit area of the steel bar. , Is the yield point σs°
