BMP Slope Protection
BMP G50/2 tecco mesh is a high-tensile, rhomboid (diamond) steel wire mesh using 2.0 mm wire and an ≈ 50 mm inscribed opening. Positioned between G45/2 and G65 series, it offers tighter face control than 65 mm meshes while maintaining better drainage and lower visual mass than 45 mm meshes. With knotted ends, robust coatings, and full system accessories, G50/2 is well suited to active slope stabilization, rockfall mitigation, and soil-/rock-interface facings.
2) Where G50/2 Fits in the Family
- G40/2 / G45/2 → very tight apertures for maximum surface control.
- G50/2 → mid-aperture option balancing fines retention and drainage.
- G65/3 / G65/4 / G80/3 / G80/4 / G80/4.6 → progressively larger apertures and/or heavier wires for higher capacities and openness.

4) Mechanical & Durability Notes
- High strength-to-weight: 2.0 mm high-tensile wire minimizes weight while providing strong load paths across the rhomboid grid.
- Knotted ends: maintain wire capacity to the edge, improve seam performance, and simplify panel handling.
- Corrosion protection: Zn–Al or HDG coatings provide long service life; coating class/coating mass can be specified for environmental severity.
- Unit mass & roll weight: depend on exact mesh geometry and coating; confirm on the batch test sheet.
5) Applications
- Active slope stabilization on weathered rock and soil/rock interfaces.
- Rockfall mitigation for road and rail cuttings, benches, and embankments.
- Soil-nail / rock-bolt facings where a mid-aperture mesh balances surface control and drainage.
- Aesthetic/vegetated slopes needing openness for plant growth with reliable face control.
6) System Components G50/2 tecco mesh
| Component | Function |
|---|---|
| Spike plates | Transfer anchor load efficiently into the mesh |
| Anchors / bolts | Primary connection to competent ground (self-drilling or bar anchors) |
| Boundary rope | Secures perimeters, transitions, and terminations |
| Sewing (lacing) rope | Joins adjacent panels; maintains continuity and load paths |
| Connection clips/clamps | Rapid local connections where specified |
7) Design & Selection Guidance G50/2 tecco mesh
-
Aperture choice:
-
Need more fines retention and surface control → consider G45/2.
-
Need more drainage/visibility with good control → G50/2.
-
Need maximum openness or heavier capacity → G65/G80 series.
-
-
Edge detailing: use boundary rope on all free edges and transitions.
-
Seams: sew/lace along full seam length at the specified pitch; add clips where required.
-
Anchor layout: grid and embedment based on design loads and substrate; use spike plates for load transfer.
-
Pretension: torque anchors per design to ensure mesh contact and limit slip.
8) Installation Summary (Good Practice)
- Survey & design the anchor grid, panel layout, edge treatment, and seam/lacing plan.
- Drill & set anchors; verify embedment; fit spike plates and nuts; pretension to specification.
- Place panels; align diamonds with load paths; secure edges with boundary rope.
- Sew/lace panels at the specified pitch; maintain uniform tension; add clips where required.
- Final check: verify torque, contact, overlaps/terminations, and overall continuity.
9) Quality & Documentation
- Manufactured from high-tensile steel wire with controlled tolerances.
- Batch test certificates available (wire strength, coating class/mass, unit mass if requested).
- Submittals typically include: panel schedule, anchor layout, spike plate details, lacing method, inspection/acceptance criteria.
10) Ordering Checklist (G50/2)
- Model: G50/2 tecco mesh.
- Wire & coating: 2.0 mm; specify Galfan or HDG and coating mass/class.
- Opening & geometry: ≈ 50 mm inscribed opening; request diagonal dimensions on the quote.
- Roll size: width × length within 1.0–3.9 m × 10–30 m.
- Accessories: spike plates, anchors/bolts, boundary rope, sewing rope, clips.
- Certificates: request project-specific datasheet with rated tensile (kN/m), puncture, shear, unit mass, and coating certificates.
11) Frequently Asked Questions
Q1: How does G50/2 differ from G45/2?
G50/2 has a slightly larger opening, improving drainage and reducing visual mass while still offering strong surface control.
Q2: When would I pick G50/2 over G65/3?
When you need more fines retention and closer face control than a 65 mm aperture provides but want to avoid the very tight 45 mm grid.
Q3: Can G50/2 be supplied in stainless steel?
Yes, stainless options can be produced on request for highly aggressive environments; confirm wire grade, coating (if any), and lead time.
Q4: What certified values will I receive?
Your project datasheet will list mesh tensile per meter width, puncture/shear resistances, unit mass, and coating data for the exact build you order.
12) Conclusion G50/2 tecco mesh
BMP G50/2 tecco mesh delivers a balanced, mid-aperture solution for slope stabilization and rockfall protection. With 2.0 mm high-tensile wire, ≈ 50 mm openings, knotted edges, durable coatings, and a complete accessory system, it provides dependable face control, efficient drainage, and long-term performance. It is an excellent choice when G45/2 is too tight and G65 meshes are too open.
