2, so there is no problem of poor ductility.

3. The thickness and spacing of steel bars are the same, so there is no problem of saving steel bars.

4. Slimming steel bars and cold-rolled ribbed steel bars are not the same thing.

5, so to sum up, most of them still consider construction. It is not easy to slide and deform when binding the steel bar at the bottom of the plate with cold-rolled ribbed steel bar; It is not easy to trample and deform when making the upper reinforcement. So my personal suggestion is to use cold-rolled ribbed steel bars.
