Batang Pengikat 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. |

Panduan Pembelian
- Confirm rod diameter and required load class with your structural engineer
- Match cone, sleeve and wing nut threads to the rod before ordering
- Request mill certificates (EN 10204 3.1) for structural applications
- For outdoor or aggressive environments, specify HDG 45–85µm or Dacromet

Perbandingan Batang Pengikat D15 vs D20
Kedua batang diproduksi di jalur yang sama, dengan grade dan pelapisan yang sama — pilihan tergantung pada beban yang ditanggung dinding dan jarak pengikat yang diizinkan desain formwork Anda.
| Parameter | D15/17 (DW15) | D20/22 (Rd20) |
|---|---|---|
| Ulir | DW15: akar 15 mm, OD 17 mm, pitch 7,5 mm | Ulir kontinu Rd20 |
| Tegangan perkiraan | ≈150 kN | ≈230 kN |
| Grade | 4.8 / 8.8 / 10.9 sesuai ISO 898-1 | 4.8 / 8.8 / 10.9 sesuai ISO 898-1 |
| Material | Q235 / 45# / 40Cr / 20MnTiB | Q235 / 45# / 40Cr / 20MnTiB |
| Penggunaan umum | Formwork pelat dan dinding standar | Dinding bertekanan tinggi, kolom, bekisting jembatan |
| Panjang | 200–9000 mm, potong sesuai ukuran | 200–9000 mm, potong sesuai ukuran |
Angka tegangan bersifat perkiraan nilai tipikal — kapasitas aktual tergantung pada grade dan material yang dipilih; seleksi akhir harus diverifikasi terhadap desain formwork Anda.
FAQ Teknis
Batang Pengikat Kuat Tinggi D15/17 — Jawaban untuk Insinyur dan Pembeli
Standard diameters cover D15 and D20, with bar length cut to the wall thickness plus the required allowance for nuts, plates and walers. Non-standard diameters and lengths can be produced to drawing.
