Pasak Kuat Tinggi D15/17
Produced on CNC thread-rolling lines for burr-free threads and consistent geometry. DW15 (15mm root / 17mm outer thread, 7.5mm pitch) third-party tested tensile capacity by material: Q235 100-110 kN, 45# 120-140 kN, 40Cr 140-160 kN, precision-rolled 180 kN (values are tested tensile, not allowable working load — divide by the applicable safety factor for design); Rd20 reaches approximately 230 kN rated per factory data. Threads follow DIN 976, A193 B7 or GB/T 15389; materials range from Q235 to 45#, 40Cr and 20MnTiB with plain, electro-galvanized, hot-dip galvanized or Dacromet finishes.

| 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. |

Perbandingan Tiub Pengikat D15 vs D20
Kedua-dua rod dihasilkan pada jalur yang sama, mengikut tahap dan perlindungan yang sama — pilihan bergantung pada beban yang dibawa dinding dan jarak pengikat yang dibenarkan dalam rekabentuk bentuk anda.
| Parameter | D15/17 (DW15) | D20/22 (Rd20) |
|---|---|---|
| Ulir | DW15: punca 15 mm, OD 17 mm, pitch 7.5 mm | ulir berterusan Rd20 |
| Tegangan anggaran | ≈150 kN | ≈230 kN |
| Tahap | 4.8 / 8.8 / 10.9 mengikut ISO 898-1 | 4.8 / 8.8 / 10.9 mengikut ISO 898-1 |
| Bahan | Q235 / 45# / 40Cr / 20MnTiB | Q235 / 45# / 40Cr / 20MnTiB |
| Guna biasa | Bentuk pelat dan dinding biasa | Dinding bertekanan tinggi, tiang, struktur jambatan sementara |
| Panjang | 200–9000 mm, dipotong mengikut ukuran | 200–9000 mm, dipotong mengikut ukuran |
Angka tegangan adalah nilai anggaran tipikal — kapasiti sebenar bergantung pada tahap dan bahan yang dipilih; pemilihan akhir harus disahkan mengikut rekabentuk bentuk anda.
