Double Twisted Hexagonal Wire Mesh | Galvanized, PVC-Coated

Galvanized Hexagonal Gabion Mesh: field notes from the slope

If you spend enough time on riverbanks and cut slopes (I do), you start to appreciate how a humble double twisted hexagonal wire mesh can quietly hold a hillside together. This product, often called “gabion mesh,” is the workhorse behind resilient retaining walls, scour protection, and habitat-friendly infrastructure. The model I’ve been reviewing lately is the Galvanized Hexagonal Gabion Mesh from TiKe Metal—manufactured in Hebei Province, east side of Baoheng Road, Zhaobazhuang Village, Tangfeng Town, Shenzhou City, Hengshui City. Real plant, real steel, no mystery.

What’s inside the basket: specs that matter

Mesh aperture (mm) 60×80, 80×100, 100×120 (project-driven)
Wire dia. (mesh/selvage/lacing) ≈2.2–3.0 / 3.0–3.9 / 2.2–2.7 mm (real‑world use may vary)
Coating options Heavy galvanizing ≥245 g/m²; Zn–5%Al (Galfan) ≥215 g/m²; PVC/PE jacket ≈0.5 mm
Tensile strength ≈380–550 MPa (low-carbon steel wire per EN 10223‑3)
Common sizes 2×1×1 m; 2×1×0.5 m; mattresses 6×2×0.23 m
Service life ≈20–60 years, environment dependent (soil pH, salinity, UV)

Standards and tests? EN 10223‑3 for hex mesh; ASTM A975 for gabions; coating per ASTM A641/A641M or EN 10244‑2; zinc mass verified via ASTM A90/A90M; tensile via ASTM A370. I know, alphabet soup—but it keeps walls standing.

Process flow (shop-floor snapshot)

Material prep → double-twist weaving (no unravel mode) → heavy galvanizing or Galfan → optional PVC/PE extrusion → panel cutting & selvedge edging → assembly with diaphragms → 100% visual check + random tensile, coating mass, and aperture audits → bundling/palletizing. Typical salt-spray on jacketed wire exceeds 1,000 h; field baskets usually accept 80–200 mm rock fill for good interlock.

Where it shines (and why engineers keep using it)

  • River training and scour pads—permeable, energy-dissipating.
  • Retaining and reinforced soil walls—flexible, crack-tolerant.
  • Coastal revetments—PVC-jacketed versions shrug off spray.
  • Culvert inlets/outlets—cheap insurance during floods.
  • Mining and terrains—temporary works that become permanent.

Industry trend check: specifiers are shifting to Zn–Al coatings and green infrastructure. Honestly, the ecological angle—voids that vegetation colonizes—wins public meetings more than any chart.

Vendor snapshot (my quick comparison, not gospel)

Vendor Coating mass Mesh uniformity Lead time Certs Field support
TiKe Metal (Hebei) ≈230–275 g/m² ±3 mm/10 apertures 7–15 days ISO 9001; CE doc set On-call + drawing review
Import aggregator ≈180–230 g/m² ±6 mm 25–40 days Supplier declarations Email only
Local fabricator varies ±5 mm In stock/spotty Mixed Site visits sometimes

Customization notes

Aperture selection to match rock gradation, diaphragms every 1 m, PVC colors (grey/green), pre-attached geotextile on mattress base, and palletized export packs. Many customers say pre-cut lacing wire speeds installation more than they expected.

Two quick case snippets

  • ASEAN riverbank, 2.3 km: double twisted hexagonal wire mesh mattresses (100×120, PVC) cut local velocities by ≈35%; post-monsoon inspections showed
  • Rockfall berm, western US: 2×1×1 m baskets with Galfan wire; after a freeze–thaw cycle winter, survey reported no unraveling, zinc mass loss within ASTM A90 expectations.

Field feedback is blunt: “It’s forgiving.” Contractors like that double twisted hexagonal wire mesh tolerates settlement without splitting. Engineers like the permeability and the fact vegetation eventually hides the structure. Honestly, that’s a win-win.

Manufactured origin: East side of Baoheng Road, Zhaobazhuang Village, Tangfeng Town, Shenzhou City, Hengshui City, Hebei Province.
