D15/D20 High Tensile Formwork Tie Rod

This series of tie rods are the core load-bearing components for steel formwork wall reinforcement, designed to withstand lateral pressure during concrete pouring. Adopts domestic universal coarse thread, equivalent to international DW standard system. The thread is not easy to be blocked by slurry and can be cut freely on site, compatible with most steel frame formwork systems. With hot-dip galvanized finish for excellent rust and corrosion resistance, it is reusable for multiple turnarounds and widely used in wall, column, bridge, tunnel and other infrastructure projects.

• High Load Bearing Capacity
  Made of high-grade 45# carbon structural steel with quenching and tempering treatment, it delivers stable tensile strength to resist high lateral concrete pressure, effectively avoiding formwork burst during pouring.
• Universal Standard Compatibility
• Equivalent to international DW standard thread system, fully interchangeable with mainstream formwork systems worldwide. No modification required for on-site replacement.
• Excellent Corrosion Resistance
  Hot-dip galvanized surface provides long-lasting rust and corrosion protection, suitable for harsh outdoor, coastal and high-humidity construction environments.
• Flexible On-site Construction
  The coarse thread design is not easy to be blocked by concrete slurry. It can be cut freely on site to adapt to different wall thicknesses, improving construction efficiency.
• Long Reusable Life
  High strength and wear resistance support multiple turnovers, reducing comprehensive cost of the project.

• Wall and column formwork reinforcement for commercial, residential and industrial building projects
• Bridge pier, abutment and cap beam formwork construction for highway and railway infrastructure
• Tunnel lining, dam and retaining wall formwork for water conservancy and municipal underground projects
• D15 model for conventional formwork projects; D20/D26 models for heavy-load projects such as high piers, thick walls and large-scale dams
