| Grade | Catatan |
|---|---|
| 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. |

Cincin Plum — Jawapan untuk Jurutera dan Pembeli
Tie spacing is governed by the maximum lateral pressure of fresh concrete, which depends on pour rate, concrete temperature, slump and wall height, plus the allowable load of the rod, the waler and the panel facing. Spacing must be calculated per pour, not copied from a previous project.
