Embedded Channels, T-Bolts & Anchors
Hot-rolled cast-in channels that replace welded and drilled fixings in concrete — fast installation, serrated load transfer and corrosion protection rated for metro and utility corridor service.
Cast-In Channels — YE-YMC
- Hot-rolled in one pass — lower residual stress than fabricated channels
- Durable & environmentally sound — complete anti-corrosion system with hot-dip, alloy-coated and stainless options
- Nationally tested — multiple test reports from the national test center
- Flexible lengths — cut or rolled to project requirements; curved versions for tunnels and circular walls
| Item No. | Model | Section (mm) | Rivet Ø (mm) | T-Bolt |
|---|---|---|---|---|
| 71002 | Channel YE-YMC-30/20 | 30 × 20 × 3 | 8 | M8 – M10 |
| 71003 | Channel YE-YMC-38/23 | 38 × 23 × 3 | 10 | M10 – M16 |
| 71004 | Channel YE-YMC-53/34 | 53 × 34 × 3 | 10 | M10 – M16 |
| — | Curved YE-YMC-30/20 · 38/23 · 53/34 | as above | 8 / 10 / 10 | M8 – M16 |
T-Head Bolts
The T-head locks into the channel groove through mechanical keying — no slip, suitable for dynamic and seismic loads; pairs with the ribbed channel for three-directional load transfer.
| Item No. | Model | Spec. | Channel | Grade |
|---|---|---|---|---|
| 71008 | T-Bolt | M12 × 40 | 30 / 20 | 8.8 |
| 71009 | T-Bolt | M12 × 40 | 38 / 23 | 8.8 |
| 71010 | T-Bolt | M12 × 40 | 53 / 34 | 8.8 |
Undercut Anchors — High Load
For cracked concrete: clear installation marks on the anchor, load-bearing at low torque with full mechanical interlock, and low expansion stress for close edge and spacing applications.
| Item No. | Model | Length (mm) | Embedment (mm) | Design Load (kN) |
|---|---|---|---|---|
| 41039 | Undercut Anchor M12×110 | 110 | 90 | 31.61 |
| 41040 | Undercut Anchor M12×130 | 130 | 120 | 55.68 |
Wedge Anchors
Cold-formed for ductility; the specially designed expansion clip grips reliably with minimal torque. Widely used for through-type fixings, backed by national test reports.
| Item No. | Model | Length (mm) | Embedment (mm) | Design Load (kN) |
|---|---|---|---|---|
| 41037 | Wedge Anchor M10×90 | 90 | 70 | 7.0 |
| 41038 | Wedge Anchor M12×100 | 100 | 85 | 9.0 |
Where Embedded Channels Work Best
Utility tunnels, metro structures, wall-mounted cantilever brackets and anywhere welding or drilling into structure is restricted.
