Cold-rolled ribbed steel bars strengthen project quality assurance testing. In order to ensure that substandard steel do not go up in the project, you should pay attention to the detection of steel: One shall not use cold-drawing process to produce shoddy products notch; the second is not recognized by the production license and permit inspection of the use of the company's products are not allowed to use; Third, strengthening the manufacturers to establish a quality assurance system, not the factory rejects. Liang provisions in the specification, the column ends rod rebar stirrups to be encrypted, its purpose is to ensure that under seismic loads and vertical frame beam plastic hinge zone and column ends have sufficient shear capacity rebar rod , while also increasing restraints on concrete stirrups to ensure the realization of the beam hinge mechanism to ensure the end of the column ductility steel wire rod manufacturers, to prevent buckling of longitudinal reinforcement. From watching these purposes, is to ask the stirrups sufficient number and density, in order to improve the shear capacity of beams bend ductility. Steel wire rod plant, Henan steel wire rod, cold rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province.
