The difference between round steel and other steel bars

1. The appearance is different. The round steel has a smooth round shape with no lines or ribs. The surface of other steel bars has grooves or ribs. This results in a small bonding force between the round steel and the concrete, while the bonding force between the other steel bars and the concrete is small. Great adhesion.

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

3. The strength is different. Round steel has low strength, while other steels have high strength. That is, compared with other steel bars, round steel with the same diameter can withstand less tensile force than other steel bars, but the plasticity of round steel is smaller than that of other steel bars. Strong, that is, the round steel has a larger deformation before being pulled off, while the deformation of other steel bars before being pulled off is much smaller.
