The shape and purpose are slightly different.
1. The surface of threaded steel bars has threads, which can increase the friction between the steel bars and concrete, improve the tensile strength and seismic performance of the steel bars, and are suitable for large buildings and bridges.
2. Deformable steel bars are processed into irregular protrusions and depressions on the surface of the steel bars, which can increase the bonding force between the steel bars and concrete, improve the bending strength and compressive performance of the steel bars, and are suitable for ordinary buildings and underground engineering. Steel reinforcement is a commonly used type of steel in construction engineering, mainly used to enhance the tensile strength and seismic performance of concrete.
