Embedded Tie Rod Assembly
Embedded before pouring, the J-hook (dimensioned as diameter × length × hook width × hook length × thread) transfers formwork load into the cured concrete for single-sided concreting and foundation anchors. Supplied with positioning templates, anchor plates and full inspection documentation; hot-dip galvanized for long-term embedment.
Specifications
- J / L hook embedded anchors
- Diameter 12–36mm, custom length
- Positioning template included
- Anchor plate and nut options
- HDG finish for embedment

06Material Grades Explained
| 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. |

Technical FAQ
Embedded Tie Rod Assembly — Answers for Engineers and Buyers
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).
