With an unparalleled project portfolio that includes supplying more major Chinese bridge projects than any other enterprise, we bring proven reliability and scale to global engineering teams. These tension members deliver exceptional tensile strength, superior fatigue resistance, and long service life, making them the trusted choice for engineers and contractors worldwide to ensure structural safety, stability, and durability.
Proven Performance from a Leading Supplier
Benefit from the expertise of China's foremost manufacturer. Our tie rods are validated by their extensive use in China's vast and complex bridge network, demonstrating their capability to perform in the most challenging real-world conditions.
Exceptional Strength and Stiffness
Manufactured from high-quality alloy steel (such as 42CrMo, 40Cr), offering yield and tensile strengths significantly higher than standard carbon steel. Capable of withstanding extreme tensile loads and dynamic stresses, ensuring structural integrity under severe conditions.
Superior Fatigue Resistance
Precision machining and heat treatment processes provide excellent fatigue performance, enabling the rods to endure millions of stress cycles. This is critical for bridges and structures subjected to dynamic loads like wind and traffic.
Precise Dimensions and Tolerances
Advanced machining technology guarantees thread accuracy and rod straightness. Ensures perfect fit-up with connectors (such as clevises, turnbuckles) for fast, secure on-site installation.
Excellent Corrosion Protection
Multiple coating options are available to meet demanding environmental requirements:
Hot-Dip Galvanizing: Cost-effective corrosion protection suitable for most environments.
Epoxy Zinc-Rich Coating: Provides superior chemical resistance and long-term durability.
Stainless Steel Option: 304 or 316 stainless steel material available for highly corrosive environments (e.g., coastal, industrial areas).
Full Customization Service
We customize tie rods according to your project drawings and specifications, including various diameters (M36 to M150 and above), lengths, and end connection types (such as threaded ends, clevis ends, hinge ends).
Our products are designed and manufactured in strict compliance with international design and manufacturing standards, ensuring global applicability, safety, and reliability.
Compliant Design: Product design conforms to key codes including EN 1993-1-11 (European Standard for Steel Structures) and AISC 360 (American Institute of Steel Construction), ensuring system safety under various load cases.
Standard Materials: Core steel complies with international material standards such as ASTM A572/A572M (High-Strength Low-Alloy Columbium-Vanadium Structural Steel), ASTM A193/A193M (Alloy-Steel and Stainless Steel Bolting Materials), and EN 10025 (Hot rolled products of structural steels).
Precision Manufacturing: Thread processing conforms to standards like ISO 898-1 and ISO 965, ensuring connection accuracy and strength.
Quality Assurance: We operate under an ISO 9001 Quality Management System and can provide inspection reports from authoritative third-party agencies such as SGS and Bureau Veritas. All critical components undergo 100% ultrasonic testing.

The cables for suspension bridges are primarily used in various cable structure systems, including cable nets, cable trusses, cable domes, and hybrid systems such as cable-stayed structures, string structures, cable-arch structures, and suspendomes that combine flexible cables with rigid components. They are also essential for glass curtain wall systems. These structural cables are valued for their aesthetic appeal, innovative anchorage design, and high anchoring efficiency. They contribute to creating lighter, more beautiful, and cost-effective building structures, making them particularly suitable for public venues like airports and stadiums that prioritize visual appeal.
