High-strength steel rod as a major force components in the construction work, the more common use in all types of construction work of the foreign. Domestic high-strength steel rod (mainly Rel ≥ more than 460Mpa steel rod) all rely on imports, only the general strength of the steel rod (relative to Rel ≥ of 460Mpa the steel rod, refers Rel ≥ 235Mpa Rel ≥ 345Mpa steel The Rod) production in a small number of domestic manufacturers, the lack of a competitive advantage.
Achieved a major breakthrough in the development of high-strength steel rod products, material selection, heat treatment, forging process, tensile testing, and the creation of a number of technological achievements of high-strength steel rod. The overall performance of the successful development of high-strength steel rod has reached more than similar products in the international advanced level of technology.
