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
Disc Nut — 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.
