In high-risk conflict zones, Hesco barriers with Galfan-coated steel wire have become the gold standard for securing military checkpoints and camp perimeters. Combining advanced metallurgy with modular design, these systems address evolving threats while reducing long-term maintenance costs.
Why Galfan Coating Matters
Superior Corrosion Resistance
Galfan alloy (95% zinc, 5% aluminum) provides 2-3x longer lifespan than standard galvanized steel in saltwater or desert environments—critical for UN coastal camps in Somalia or Saharan forward operating bases.
Enhanced Ballistic Performance
The smoother Galfan surface reduces bullet fragmentation risks compared to traditional zinc coatings, aligning with NATO AEP-55 volumetric weapon test standards for checkpoint barriers.
Cost-Efficiency
While initial costs are 15% higher than basic galvanized models, Galfan barriers cut replacement cycles from 5 to 12 years in tropical climates (per 2023 Journal of Military Engineering study).
Checkpoint Deployment Case
Iraqi-Kurdistan Border Crossings:
Hesco Galfan units configured into 4m-high “snake” checkpoints reduced vehicle-borne IED breaches by 92% (2022-2024 data).
UN Disarmament Camps (DR Congo):
Multi-layered perimeters with 45° angled barriers prevented unauthorized access during weapons surrender operations.
