BMP Slope Protection
TECCO mesh is a family of high-tensile, rhomboid (diamond) steel wire meshes engineered for active slope stabilization and rockfall protection. The system combines ultra-high-strength wire (typically ≥ 1770 N/mm²), knotted edges, corrosion-resistant metallic coatings, and standardized accessories (anchors, spike plates, boundary/sewing ropes, clips) to create a fast-install, durable facing that works on rock and soil/rock interfaces.
2) How TECCO mesh works
- High-tensile wire grid transfers face loads to anchors with very low elongation.
- Knotted ends keep capacity to the panel boundary and create neat, secure seams.
- Spike plates clamp the mesh to the slope at each nail and spread the load into the grid.
- Boundary rope secures edges and captures the bottom edge under spike plates; sewing (lacing) rope and clips join panels along seams.
- Open diamonds allow drainage and vegetation while providing surface control.

3) Model families (quick reference)
| Model | Wire Ø | Opening (inscribed) | Typical diamond diagonals* | Typical roll sizes** | Typical usage note |

| G65/3 | 3.0 mm | ~65 mm | ~83 × 143 mm | 3.5 m × 20 m | Standard stabilization |

| G80/4 | 4.0 mm | ~80 mm | ~102 × 177 mm | 3.5 m × 20 m | Heavy-duty slopes |
| G80/4.6 | 4.6 mm | ~80 mm | ~102 × 173 mm | 3.5 m × 10/20 m | Maximum robustness/top class |
* Diagonals are typical geometry; exact values depend on production tolerance.
** Roll sizes vary by supplier; G65/2 is commonly supplied in 3.5 m × 40 m long rolls for productivity.
4) Materials & coatings TECCO mesh
- Wire: high-tensile steel, typically ≥ 1770 N/mm².
- Coatings: Zn–Al (Galfan/ULTRA-type) or hot-dip galvanized (HDG); typical coating mass ≥ 150 g/m² with heavier classes available for aggressive environments.
- Stainless options: available on request for highly corrosive sites (confirm grade and availability).
5) Spike plates (load-transfer plates)
| Plate family | Size class (L × W × t) | Hole Ø | Typical use |
|---|---|---|---|
| P25/34 N | ~250 × 155 × 5 mm | 34 mm | Compact plate for tighter meshes (e.g., G45/2) |
| P33/40–50 N | ~330 × 205 × 7 mm | 40/50 mm | Standard workhorse for most TECCO/Spider installs |
| P66/50 N | ~667 × 300 × 7 mm | 50 mm | High-load applications; long bearing length |
All spike plates are diamond-shaped to match mesh geometry, include pressed spikes/ribs, and are installed pretensioned at each anchor.
6) Mechanical performance (typical guidance)
-
TECCO mesh tensile capacity class:
- 2.0 mm meshes (e.g., G40/2, G45/2, G50/2, G65/2, G80/2) often fall around ≈ 150 kN/m (confirm on datasheet).
- 3.0/4.0/4.6 mm variants provide progressively higher capacities and puncture/shear resistances.
-
Performance is configuration-dependent (wire tolerance, diamond geometry, coating class). Always use the project-specific test sheet for certified kN/m, puncture, shear, and unit mass.

7) Applications TECCO mesh
- Rockfall protection on road/rail cuttings, benches, portals, and quarry faces.
- Active stabilization of weathered rock and mixed soil/rock slopes.
- Soil-nail / rock-bolt facings needing open, durable, and strong surface control.
- Aesthetic/vegetated slopes where drainage and low visual mass are desired.
8) Installation workflow (good practice)
- Survey & design anchor grid, panel layout, edge treatment, and seam plan.
- Drill & set anchors; verify embedment; fit spike plates and nuts; pretension per design.
- Place panels from crest; align diamonds with load paths; treat edges with boundary rope (capture the bottom rope under lowest plates).
- Sew/lace seams at specified pitch; add clips where required; maintain uniform tension.
- Inspect & handover: torque check, contact/seat at plates, seam continuity, edge terminations, as-built documentation.
9) TECCO mesh Selection guide (which model when?)
- Need maximum surface control with low weight → G40/2 or G45/2.
- Balanced control & drainage → G50/2 or G65/2 (fast coverage with long rolls).
- General-purpose higher capacity → G65/3 or G80/3.
- Heavy-duty slopes / higher energies → G65/4 or G80/4.
- Top robustness / mining & high-energy zones → G80/4.6.
- Need very open appearance & drainage with light handling → G80/2.
10) Quality & documentation
- Manufactured under controlled tolerances for wire, geometry, and coating.
- Batch certificates available: wire strength, coating mass/class, and (on request) unit mass.
- Typical submittals: panel schedule, anchor layout, spike plate details, lacing method, inspection/acceptance criteria.
11) Ordering checklist
- Model (e.g., G65/2, G80/4.6).
- Wire & coating (diameter, Galfan or HDG; specify coating mass/class).
- Geometry (inscribed opening and requested diamond diagonals).
- Roll size (width × length; e.g., 3.5 m × 20 m, or 3.5 m × 40 m for G65/2).
