Reinforcing steel bars (rebars) are steel materials for reinforced concrete and prestressed reinforced concrete, and have a circular cross section, and sometimes a square cross section with rounded corners. Comprises plain round steel bars, ribbed steel bars and twisted steel bars. The reinforcing steel bar for reinforced concrete is straight bar or wire rod steel for reinforcing steel bar for reinforced concrete, and has two shapes, i.e. plain steel bar and deformed steel bar, and two kinds, i.e. straight bar and wire rod, in delivery state.
The yield strength is the yield limit at which the metal material yields, i.e., the stress against a slight amount of plastic deformation. For a metallic material in which no significant yield phenomenon occurs, a stress value that produces 0.2% residual deformation is specified as its yield limit, called the conditioned yield limit or yield strength. An external force greater than the yield strength will cause the part to permanently fail and fail to recover. If the yield limit of the low-carbon steel is 207MPa, the part can generate permanent deformation under the action of external force greater than the yield limit, and the part can restore the original shape even if the yield limit is less than the yield limit.
