What We Make
We produce plain and spiral-ribbed prestressed steel wire, low-relaxation PC steel strand, PE-coated unbonded strand, and hot-rolled spring steel flat bar. Raw materials are melted and rolled in our own plants, then drawn, heat-treated and finished under strict process control.
Every batch is tested for tensile strength, relaxation, ductility and hardness before delivery. We supply standard sizes and custom dimensions according to project drawings, for bridges, buildings, infrastructure, agricultural machinery and heavy equipment.
Bridges
PC strand and wire for prestressed concrete bridges, tunnels and rail projects.
Rail & Precast
Spiral-ribbed PC wire for concrete sleepers and precast components.
Highway Precast
PC strand for precast box girders and highway projects.
Who We Work With
We partner with infrastructure contractors, precast concrete factories, agricultural machinery manufacturers and steel distributors in over 70 countries. Our team provides technical support, custom sizing and on-time delivery for every project.
Our Factory & Quality
Our 280,000 m² facility in Tianjin houses complete production lines for wire drawing, heat treatment, strand stranding and flat bar rolling. We have 1,300 employees including 290 professional engineering and technical staff.
Every batch is tested using a full range of physical and chemical equipment, including direct-reading spectrometers, carbon-sulfur analyzers, universal tensile testers, stress relaxation testers, hardness testers and metallographic microscopes. We maintain strict factory-release standards to ensure 100% product qualification.
