BMP Slope Protection
BMP G40/2 tecco mesh is a high-tensile, diamond (rhomboid) wire mesh designed for active slope stabilization and rockfall protection. It uses 2.0 mm high-strength steel wire formed into knotted diamonds with close openings (~40 mm), providing excellent surface control on weathered rock and fine soils while remaining light and easy to install. The mesh is used as part of a complete system with anchors, spike plates, boundary and sewing ropes, and connection clips.
2) G40/2 tecco mesh specifications
| Item | Specification |
|---|---|

| Wire diameter | 2.0 mm (high-tensile steel) |
| Wire tensile strength | ≥ 1770 N/mm² (≈ 1770 MPa) |
| Single-wire breaking load (theoretical) | ≈ 5.6 kN (based on 2.0 mm wire at 1770 MPa) |
| Mesh geometry | Rhomboid/diamond, knotted ends (twisted/locked eyes) |
| Opening reference | ≈ 40 mm (inscribed circle of the diamond) |
| Mesh tensile capacity class* | ≈ 150 kN/m (typical for 2.0 mm variants) |
| Coating options | Zn–Al (Galfan) or hot-dip galvanized; typical coating mass ≥ 150 g/m²; heavier coatings available on request |
| Roll width (typical) | 1.0 m – 3.9 m |
| Roll length (typical) | 10 m – 30 m |
| Edge finish | Knotted ends; prepared for lacing/sewing |
| System compatibility | Spike plates, anchors/bolts, boundary rope, sewing rope, connection clips |
*Exact mesh tensile and derived resistances depend on coating, manufacturing tolerance, and test method. Certified values for a specific batch are supplied on request.
3) Dimensional detail (ordering data)
| Dimension | Value / Range | Notes |
|---|---|---|
| Inscribed opening (Dᵢ) | ≈ 40 mm | Tighter opening for better fines retention and close surface control |
| Diamond diagonals (approx.) | application-specific | The model designation is driven by the inscribed opening; diagonal lengths vary slightly with production |
| Knot/loop spacing | equals mesh pitch | Knotted ends ensure force transfer and clean edges |
4) System components (supplied/selected as needed)
| Component | Function |
|---|---|
| Spike plates | Distribute anchor load into the mesh |
| Anchors / bolts | Primary connection to the slope (self-drilling or bar anchors) |
| Boundary rope | Secures perimeter and transitions |
| Sewing (lacing) rope | Joins adjacent panels; maintains continuity |
| Connection clips/clamps | Rapid local connections where required |
5) Key benefits G40/2 tecco mesh
- High strength-to-weight: 2.0 mm high-tensile wire minimizes weight while maintaining robust capacity.
- Tight aperture (~40 mm): Excellent surface control; helps retain small fragments and thin weathered layers.
- Durable protection: Zn–Al or HDG coatings deliver long service life in harsh climates.
- Fast, safe installation: Knotted edges, modular rolls (up to 3.9 m wide), and standardized accessories speed field work.
- Environment-friendly face: Open mesh allows drainage and vegetation regrowth.
6) Typical applications
- Active stabilization of rock cuttings and soil/rock interfaces
- Rockfall and shallow debris control on slopes and embankments
- Road/rail corridor protection and portal/abutment faces
- As the facing for soil-nail and rock-bolt systems
7) Quality & documentation
- Manufactured from high-tensile steel wire with controlled tolerances.
- Batch-specific mill test certificates and coating certificates available on request.
- Project submittals typically include: panel layout, anchor pattern, spike plate details, lacing method, and inspection/acceptance criteria.
8) Installation summary G40/2 tecco mesh
- Survey & design: define anchor grid, edge ropes, overlaps (or seam sewing).
- Drill & set anchors: verify embedment; fit spike plates and nuts for pretension.
- Place mesh panels: align diamonds; maintain straight load paths; treat edges with boundary rope.
- Sew/lace panels: use specified rope/clips at the pitch recommended; keep uniform tension.
- Pretension & inspect: tighten to design torque; check contact, overlaps, and terminations.
9) Ordering checklist (BMP G40/2)
- Model: G40/2 tecco mesh
- Wire/coating: 2.0 mm, Galfan or HDG (state target coating mass if required)
- Roll size: width × length (e.g., 3.5 m × 20 m, or as needed within the ranges above)
- Accessories: spike plates, anchors, boundary rope, sewing rope, clips
- Documentation: request batch test certificates and installation notes if needed
Notes
-
Values above reflect the established characteristics of the G40/2 type. If your project requires formally certified numbers (e.g., puncture/shear resistance, exact unit mass, or salt-spray hours for a particular coating class), BMP will issue a project-specific datasheet for the exact configuration you order.
Conclusion
BMP G40/2 tecco mesh combines 2.0 mm high-tensile steel wire with a tight ~40 mm diamond opening to deliver reliable, lightweight, and durable active slope stabilization and rockfall protection. Its knotted geometry ensures efficient load transfer, while Galfan or HDG coatings provide long service life in harsh environments. Compatible anchors, spike plates, boundary and sewing ropes form a complete, fast-install system—ideal where close surface control and long-term safety matter.
