The difference between round steel and other steel bars

 The difference between round steel and other steel bars

　　1. The shape is different. The shape of the round steel is smooth and round, without grain and ribs. The surface of other steel bars has grooves or ribs, which results in a small bond between the round steel and concrete, while other steel bars and concrete. Strong adhesion.

　　2. The composition is different. Round steel (first-grade steel) belongs to ordinary low-carbon steel, and other steel bars are mostly alloy steel.

　　3. The strength is different, the strength of round steel is low, and the strength of other steel is high, that is, compared with other steel bars, round steel with the same diameter can bear less tensile force than other steel bars, but the plasticity of round steel is higher than that of other steel bars. Strong, that is, the round steel has a large deformation before being broken, while the deformation of other steel bars is much smaller before being broken.
