Shandong Zhonggui Equipment Co., Ltd.
At the CRTS III ballastless track slab production line in the Jinan production base, Shandong Zhonggui Equipment has been
In Jinan, at the advanced production facility of Shandong Zhonggui Equipment Co., Ltd., our high-performance prestressed steel wire is playing a pivotal role in the manufacturing of CRTS III ballastless track slabs—the backbone of modern high-speed railway infrastructure.
The Challenge: The production of CRTS III slabs demands rigorous precision. The materials must withstand extreme fatigue while maintaining structural integrity. Furthermore, to meet high-volume production targets, Shandong Zhonggui needed a supply solution that could integrate seamlessly with their automated tensioning systems to minimize downtime.
The Solution: We supplied our premium 1570 MPa, Ø6.25 mm Spiral Rib Prestressed Steel Wire.
Seamless Integration: Delivered in full coil form, our wire connects directly from the warehouse to the production line, enabling continuous, automated feeding.
Superior Bonding: The spiral rib design ensures exceptional grip within the concrete, essential for the safety of track slabs.
Key Results:
Ultra-Low Relaxation: With a relaxation rate of <1.5% at 1000 hours (under 70% max stress), our wire ensures long-term tension stability.
Enhanced Durability: The solution significantly improved the slab's crack resistance life, reducing long-term maintenance costs for the railway operator.
Operational Efficiency: The stability of the wire significantly reduced the frequency of maintenance adjustments during the tensioning process. Backed by our timely technical support and stable bulk supply, Zhonggui Equipment has achieved efficient, uninterrupted operations across multiple lines.
