Advantages
1. Strength You Can Trust
We understand that not all projects have the same demands. That’s why we offer tiered material options to match your specific structural and budgetary needs:
- Premium Grade: For high-stress applications, we recommend our #45 steel tie rods, manufactured through hot-rolling processes. These deliver exceptional tensile strength—up to 185-190 kN for D17mm and over 200 kN for D20mm—ensuring maximum safety and reliability in demanding environments.
- Standard & Economical: For projects with standard load requirements, our Q235 cold-drawn tie rods provide dependable performance with a tensile strength of 130-140 kN, offering a cost-effective solution without compromising essential integrity.
2. Precision & Versatility in Design
- Full Size Range: Our tie rods come in industry-standard diameters (D15/17mm, D20/22mm) and can be custom-cut to your required length.
- Comprehensive Nut Selection: We supply a complete range of nuts—including round nuts, wing nuts, swivel nuts with round plates, hex nuts, water stoppers, and washers—in diameters from D90 to D120mm. All nuts are made from consistent QT450 steel, ensuring uniform durability across types.
3. Quality Controlled at the Source
Based in Tianjin—a major industrial and logistics hub—we have direct access to high-quality raw materials and maintain strict in-house quality control throughout production. This allows us to guarantee product consistency, traceability, and compliance with both British and metric measurement standards.
4. Global Compliance & Adaptability
Our products are trusted across Southeast Asia, the Middle East, Europe, and the Americas. We recognize that each market has unique standards and expectations. Rather than a one-size-fits-all approach, we offer tailored quality levels—helping you select the right product for your local requirements, climate conditions, and safety regulations.
5. Honest Guidance, Not Just a Sales Pitch
In a market where quality can be uneven and price often overshadows performance, we stand by the principle: “Quality First, Customer Foremost, Service Utmost.” We take the time to understand your project’s real needs and recommend the most appropriate solution—whether it’s premium #45 steel for critical structures or reliable Q235 for standard formwork.
6. Built for System Integrity
More than just components, our tie rods and nuts are engineered to work seamlessly within your entire formwork system. They ensure tight, secure connections between formwork and wall, reducing the risk of leaks, misalignment, or failure during concrete pouring.
