Formwork tie rods

Formwork Tie Rods are critical load-bearing components in concrete pouring projects, designed to connect and tension opposing formwork panels against the immense lateral pressure of fresh concrete. Manufactured from high-strength alloy steel through precision machining and heat treatment, our tie rods offer exceptional tensile strength and durability. We provide a comprehensive range, including through-tie rods and disposable threaded tie rods, to deliver safe, efficient, and cost-effective solutions for formwork projects of all scales and complexities, ensuring precise concrete dimensions and smooth surface finishes.

Description

Product Name: Formwork Tie Rods
Key Features:
- High Tensile Strength: Made from high-strength alloy steel (e.g., 45Mn, 40Cr), our rods withstand extreme concrete pressure, preventing formwork failure and ensuring worksite safety.
- Comprehensive Specifications: Available in various diameters (M12, M16, M18, M20, M24, etc.) and lengths, with custom options to suit diverse needs, from walls/columns to large foundations and bridge piers.
- Economic & Efficient (for Disposable Type): The innovative three-part tie rod system allows the outer parts and nuts to be reused while the inner section remains in the concrete. This saves material costs and leaves a small, neat hole in the finished wall.
- Corrosion Resistance: Surface treatments like galvanization (hot-dip or electro) or Dacromet provide excellent rust resistance, ensuring longevity even in harsh environments.
- Easy Installation: Standardized threading works seamlessly with cone nuts and washers for quick assembly and disassembly, significantly boosting on-site productivity.
Product Types:
- Through-Tie Rods: Feature continuous threading and are used with PVC sleeves. Suitable for thinner walls and are fully retrievable.
- Disposable Threaded Tie Rods (3-Part System): Consist of an inner wedge and two outer rods. The outer components are reusable, making this a cost-effective and popular choice for modern formwork.
Applications:
- Formwork for building walls, shear walls, and columns
- Large-scale infrastructure: bridge piers, tunnel walls, dams
- Industrial foundations and equipment bases
- Any cast-in-situ concrete structure requiring resistance to lateral concrete pressure.
