The difference between round steel and other steel bars: 1. The appearance is different, the round steel is light and round, no grain and no ribs, and the surface of other steel bars has engravings or ribs, which causes the adhesion between round steel and concrete to be small, while the adhesion of other steel bars and concrete is large. 2. The composition is different, round steel (first-class steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel. 3. The strength is not the same, the round steel strength is low, and the strength of other steel is high, that is, the round steel with the same diameter size Compared with other steel bars, the round steel can withstand less tensile force than other steel bars, but the plasticity of round steel is stronger than other steel bars, that is, the round steel has a large deformation before being pulled off, and the deformation of other steel bars before being pulled off is much smaller.
