D15 / D20 High-Strength Tie Rods

Produced on CNC thread-rolling lines for burr-free threads and consistent geometry. DW15 (15mm root / 17mm outer thread, 7.5mm pitch) carries approximately 150 kN allowable tension, while Rd20 reaches approximately 230 kN. Threads follow DIN 976, A193 B7 or GB/T 15389; materials range from Q235 to 45#, 40Cr and 20MnTiB with plain, electro-galvanized, hot-dip galvanized or Dacromet finishes.

  • DW15 and Rd20 all-thread bars
  • D15 ≈150 kN / D20 ≈230 kN allowable tension
  • Length 200–9000mm, cut to length
  • Q235 / 45# / 40Cr / 20MnTiB

Five-Section Water Stop Tie Rod
Tie Rods & Water Stop Rods

Five-Section Water Stop Tie Rod

The five-section design leaves the water stop plate embedded in the wall while the outer cones and threads are recovered after concreting, eliminating through-hole leak paths. Water stop plates are supplied welded (e.g. 120×120mm sheet or Ø65mm round) in fixed or movable types for D14/D15/D20 rods, with matching PVC cones and rubber seals.

  • D14 / D15 / D20 rod options
  • Removable middle section, recovered outer parts
  • Water stop plate welded or movable, 120×120 or Ø65
  • PVC cones and rubber seals matched to wall thickness

FAQ

Formwork Fastener Products

A formwork tie rod is a high-strength threaded bar that, together with nuts, anchor plates and walers, holds formwork panels against the lateral pressure of fresh concrete. It passes through the wall section and is either fully recovered after stripping (through-tie used with a sleeve) or permanently embedded (lost-end / water-stop type).
