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
Mountain Disc (Mountain Plate) — 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).
