Proteksyon ng BMP Slope
BMP G80/4.6 tecco mesh is the most robust model in the BMP tecco range. Built from 4.6 mm high-tensile steel wire and formed into rhomboid (diamond) cells with an ≈ 80 mm inscribed opening, it delivers exceptional capacity for demanding geotechnical conditions—steep rock faces, dynamic rockfall zones, and mining ground support—while remaining modular and field-friendly. Knotted ends ensure strong load transfer and tidy, secure edges. The mesh integrates with anchors, spike plates, and lacing systems to create a complete, high-performance facing.
2) Key Advantages G80/4.6 tecco mesh
- Maximum robustness within the BMP tecco family
- High strength-to-weight from ultra-high-tensile wire (≥ 1770 N / mm²)
- Large aperture (≈ 80 mm) for drainage, vegetation, and reduced visual impact
- Knotted edges for reliable force transfer to boundaries and seams
- Durable coatings (Zn-Al or HDG) for long service life in harsh climates
- Systemized installation with compatible anchors, spike plates, and ropes

| Anchors / mga bolts | Primary connection to competent ground (self-drilling or bar anchors) |
| Boundary rope | Secures perimeter, transitions, and terminations |
| Sewing (lacing) rope | Joins adjacent panels; maintains continuity and load paths |
| Connection clips/clamps | Rapid local connections where specified |
6) Installation Summary (Good Practice)
- Survey & Disenyo: define anchor grid, panel layout, overlaps or seam sewing.
- Drill & set anchors: verify embedment; fit spike plates and nuts; pretension per design.
- Place panels: align diamonds with load paths; secure edges using boundary rope.
- Sew/lace panels: apply specified lacing pitch; keep uniform tension; add clips where required.
- Pretension & inspect: tighten to the design torque; check contact, overlaps, and terminations.
