The difference between round steel and other steel bars

1. The appearance is different. The round steel has a smooth and round appearance, no pattern and no ribs, and other steel bars have engraved or ribbed appearance on the surface. This results in a small bonding force between the round steel and the concrete, while the other steel bars and concrete have a small bonding force. Great 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 the round steel is low, and the strength of other steels is high, that is, the round steel with the same diameter can withstand less tensile force than other steel bars, but the plasticity of the 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.
