Works with the development of high-•∑αstrength steel tie rods ¥ ÷✘in order to meet the needs of many¥'← domestic projects of high-strengt↔¥>←h steel rod supporting. T® he products in the country, mainl∑≥α✔y by imports, to revitalize national©↔×> industry and to break t≤÷$ he monopoly on the stee​≈λl trolley international market of ≥♦©$Britain, France, German'÷y, Luxembourg, and a few othe>λ↕r countries, making the localizatio♠÷n of steel rod has been a¶↔←pplied in the domestic market and to ∑‌>☆to enter the international m•"σ↓arket.
High-strength steel rod as a major fo↔★∏£rce components in the construct​≠↕→ion work, the more common useγλ in all types of constru∏ ♠ction work of the foreγ✘ign. Domestic high-s&≈trength steel rod (mainly R♣<→™el ≥ more than 460Mpa£σλ© steel rod) all rely on imports, onl£✔↔y the general strength of the sα¶♠↔teel rod (relative to Re δ×l ≥ of 460Mpa the steel rod, refers∞  Rel ≥ 235Mpa Rel ≥ 345Mp✘≠a steel The Rod) production in a sΩ<≤mall number of domestic manufacturers, ∞π®™the lack of a competitive advaΩ ×£ntage.
Achieved a major breakthro€β∏ugh in the development of hδ✔¥igh-strength steel rod pr≤≥↕oducts, material selection, heat trea'γtment, forging process, tensile tes•>ting, and the creation€©  of a number of technological aλ©chievements of high-strength steel r♠×od. The overall perform&×ance of the successful developmen™∞‍ t of high-strength steel rod haΩ<βs reached more than si←®¶₩milar products in the in ‌ternational advanced leλ∞vel of technology.
