rockfall protection netting price depends on mesh strength, energy class, coatings, post spacing, and installation method; below is a clear, data-driven breakdown you can use to compare suppliers fast.
Real costs are driven by four levers: energy class (100–3000 kJ), mesh type (ring-net vs. high-tensile), corrosion protection (HDG, Galfan, stainless), and installation complexity (anchors, posts, terrain, access).
USD 28–45/m² for high-tensile drapery (65×65 mm, 3.0–4.0 mm); USD 80–145/m for ring-net barrier systems at 250–1000 kJ (ex-works, material only).
Anchors per post, drilling length, grout, labor rates, and terrain access can double the material cost. Request line-item quotes for posts, brake elements, ropes, and anchors.
Higher energy classes require heavier rings, stronger ropes, taller posts, and larger brake elements, which raise the overall system price per meter.
For durable performance, buyers often choose TECCO mesh (G65/3 or G80/4), ring net spirals (Ø300×3.0 mm), and ropes in 7×7 or 7×19 configurations at 12–22 mm with HDG or Galfan coatings.
Combine energy class, post spacing, anchor lengths, and coating to build a total cost model; verify on-site with a trajectory analysis and update the bill of quantities.
| Parameter | High-Tensile Mesh (Drapery) | Ring-Net Barrier (250–1000 kJ) | Notes |
|---|---|---|---|
| Mesh Type | G65/3 (65×65 mm, 3.0 mm) / G80/4 (65×65 mm, 4.0 mm) | Spiral ring Ø300×3.0 mm (double-wrapped) | Both HDG or Galfan coating |
| Tensile Strength | ≥ 1770 MPa (wire) | ≥ 1770 MPa (ring wire) | Factory test certificates available |
| Zinc / Zn-Al Coating | HDG ISO 1461 / Galfan ≥ 200 g/m² | HDG ISO 1461 / Galfan ≥ 240 g/m² | Coastal C3–C5 options |
| Rope Diameters | Support rope 12–16 mm; lacing 8–12 mm | Upper 20 mm; lower 16–18 mm; support 12–14 mm | 7×7 / 7×19 construction |
| Barrier Height | — (drapery) | 3.0–6.0 m | Posts steel S355 |
| Post Spacing | — | 10–20 m (typical) | Depends on energy class |
| Dynamic Deflection | — | 2.5–6.0 m (typical) | Per full-scale test |
| Energy Classes | — | 100 / 250 / 500 / 1000 / 1500 / 3000 kJ | ETAG 027 / EAD testing |
| Material Price (EXW) | USD 28–45 / m² | USD 80–145 / m | Guidance only; confirm with BOQ |
| Installation Adders | Anchors 1.5–3.0 m, grout, access | Anchors 3–6 m, foundations, crane | Labor rates vary by region |
Choose between hot-dip galvanized or Galfan coatings for long service life. For aggressive coastal sites, consider stainless ropes on upper bearing lines and retain galvanized mesh to balance performance and cost.
Highways, railways, tunnel portals, and open-pit mines frequently pair ring-net barriers at 250–1000 kJ with drapery for talus control—this hybrid solution stabilizes slopes while keeping total cost predictable.
