Both Low-alloy Coupled Steels and Cold rolling belt rib steel bars are cold finishing steel bars. In project practice, Anchor ability of Low-alloy Coupled Steels Concrete will higher than cold rolling belt rib steel bars. So, more economical steel bars and cement contents. Through comparative trial about on concretes component of Low-alloy coupled steels and cold rolling belt rib steel bars in this article. Summarizes that anchor ability of Low-alloy coupled steels are depending transverse steel, well, steel bars and concretes has the better joint work ability.
