High-tech new metal materials are widely used

      Prestressed steel strands have a series of advantages such as high strength, low relaxation value, can save a lot of metal materials, reduce the size of concrete structures, and improve the grade of prestressed concrete structures. They have been widely used as important metal materials in universities, energy saving, and material saving. In transportation, energy, industrial and civil construction, water conservancy, environmental protection construction, etc.In the field of transportation, prestressed steel strands are mainly used in bridges, geotechnical anchorage, urban viaducts, rail transit lines, airport building structures and runways, large pipe piles, trestles, high load-bearing ground, etc.; in the field of energy construction, prestressed steel Strands are mainly used in the reinforcement of dams and underground powerhouses, ship locks, culverts, geotechnical anchoring, containment vessels and workshops of nuclear power plants, anchor rods of offshore oil drilling platforms and coal mining, etc. In the field of construction, prestressed steel strands are mainly used In concrete structures, steel structures, foundation projects and heavy-load lifting; in water conservancy facilities, prestressed steel strands are mainly used in hydropower stations, aqueducts, culverts, dam reinforcement, reinforcement to prevent floor floating, circumferential winding reinforcement, etc.
