Precision Rolled Tie Rod
A precision rolled tie rod: the thread is rolled over the full length instead of being cut, so the section stays continuous and a nut can be set anywhere along the rod. It is used where a heavy formwork tie runs through a wall and has to be tensioned from the accessible face, and where the same rod also serves as a prestressing bar by design. Supplied in 40Cr and PSB830/PSB930 grades; diameters, lengths and end treatment follow your drawing.
Specifications
- Precision rolled tie rod, thread rolled over the full length
- Nut can be positioned at any point along the rod
- Heavy formwork ties, including walls tied from one accessible face
- Cut to length on your drawing; diameters on request

| Grade | Notes |
|---|---|
| Q235 | Plain carbon steel. Economic option for light and medium formwork loads. Not heat treated. |
| 45# | Medium carbon steel. The standard formwork tie rod grade in China; quenchable to class 8.8. |
| 40Cr | Alloy steel. Higher hardenability and better fatigue performance than 45#; used where repeated reuse matters. |
| Class 10.9 bolt | Quenched and tempered alloy steel bolt used in the climbing cone set. Not electroplated without a documented baking cycle. |
| QT450-10 | Ductile (nodular) iron with 450 MPa tensile and 10% elongation. Used for sleeves and embedded plates where toughness and castability matter. |
| HRB400 | Hot-rolled ribbed bar (threaded steel) to Chinese standard. Used for embedded foot bolts; good bond with concrete. |

Precision Rolled Tie Rod — Answers for Engineers and Buyers
It consists of two reusable outer threaded bars, two plastic cones and one embedded middle bar with a welded water-stop plate. After stripping, the two outer bars are unscrewed and reused on the next pour; only the middle section stays inside the wall. This keeps consumable cost low while producing a watertight wall penetration.
