Round bar

difference between round steel and other steel bars: 1. The shape of round steel is different. Round steel is smooth and round, without lines and ribs. The surface of other steel bars is carved or ribbed, which results in the bonding force between round steel and concrete. Small, but the bonding force between other steel bars and concrete is large. 2. The composition is different. Round steel (first-grade steel) belongs to ordinary low-carbon steel, and most other steel bars are alloy steel. 3. The strength is different. Round steel has low strength, while other steels have high strength. Compared with other steel bars, round steel with the same diameter can bear less tensile force than other steel bars, but round steel has better plasticity than other steel bars. Strong, that is, round steel has greater deformation before being broken, while other steel bars have much smaller deformation before being broken.
