Formwork tie rods are high-strength specialized fasteners engineered to secure and stabilize concrete formwork during the critical casting process. By connecting opposite panels of the formwork, these rods counteract the immense lateral pressure exerted by fresh concrete, preventing bulging, shifting, or structural collapse. This ensures that the final concrete structure maintains precise dimensions, uniform wall thickness, and a high-quality professional finish.
Designed for versatility and extreme durability, our tie rods are manufactured from premium-grade steel to meet the rigorous demands of modern civil engineering. Whether used in residential buildings, commercial high-rises, bridges, or industrial facilities, these essential components work in tandem with nuts and washers to create a robust support system, ensuring maximum safety for workers and structural integrity for the project.

Frequently Asked Questions
Choose Q235 for light residential projects (90KN), Grade 45 for standard commercial structures (140KN), and PSB830 for high-load civil engineering like bridges (180KN).
Galvanization (Yellow or Silver) provides a protective zinc layer that prevents oxidation and corrosion, significantly extending the lifespan of the rods in humid environments.
Yes, our tie rods are designed to be compatible with various systems, including timber, steel panels, and specialized scaffolding accessories like Ringlock systems.
They act as tension members that hold opposite formwork panels together, resisting the lateral hydraulic pressure of wet concrete and preventing the forms from bursting.
They are typically used with wing nuts, hex nuts, washers, and rapid clamps to create a fully adjustable and secure fastening system.
We perform chemical analysis of the raw steel, dimensional checks on threading, and critical tensile strength tests to ensure they meet the specified break load.
