Works with the development of high-strength steel tie rods in order to meet the needs of many domestic projects of high-strength steel rod supporting. The products in the country, mainly by imports, to revitalize national industry and to break the monopoly on the steel trolley international market of Britain, France, Germany, Luxembourg, and a few other countries, making the localization of steel rod has been applied in the domestic market and to to enter the international market.
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.
