Core Application Areas of Prestressed Steel Wire Drawing Machines
1.Large-Scale Bridge Projects
Cables for cable-stayed/suspension bridges: Produces high-strength galvanized steel wire (strength ≥1860 MPa) with a diameter of 5-7 mm for load-bearing cables (e.g., a single strand of the Shanghai-Suzhou-Jiangyin Yangtze River Bridge contains 127 wires).
Box girder prestressing tendons: Spiral ribbed steel wire or notched steel wire with a diameter of 4-12mm is manufactured to improve the bending resistance of concrete beams.
2.High-speed railway and rail transit systems
Sleepers (sleeper slabs): Use 7-8mm Φ prestressed steel wire (such as CRTS III slab track) to withstand dynamic train loads.
Catnel posts: Produce 5mm Φ high-precision steel wire, meeting ±0.02mm diameter tolerance requirements.
3.Energy Infrastructure
Nuclear Power Plant Containment: Manufacturing 1860MPa-grade low-relaxation steel wire for prestressed double-layer containment structures (such as the Hualong One unit).
Wind Turbine Tower Anchors: Manufacturing large-diameter (12-20mm) prestressed steel wire bundles to replace traditional steel bar anchor systems.
4.Prefabricated Buildings
Prestressed Hollow-Core Slabs/Double-T Slabs: Utilizing 9-12mm spiral ribbed steel wire, they reduce concrete usage by 30% and increase floor spans to 18 meters.
