Gateway Metalworks installed a galvanized security mesh fence along the steep mountainside boundary. Featuring reinforced concrete plinths, razor-coil topping, and a custom access gate.

The mountainside boundary runs along rocky, uneven terrain with steep gradients, demanding a fence that blocks intrusion, withstands ground movement, and meets defense sector standards.

Gateway Metalworks installed a galvanized high-security mesh fence along the full mountain boundary. The narrow-aperture mesh blocks climbing, cutting, and tool penetration, while razor-coil topping raises the deterrent level. A continuous reinforced concrete plinth seals the base against erosion and burrowing, with panels stepped up the slope to follow the gradient.

THE CHALLENGE

• • Build a continuous fence line on uneven gradients without leaving ground-level gaps.
  • Resist erosion, ground movement, and burrowing along the base of the fence.
  • Withstands coastal exposure to salt air, fog, wind, and strong sun.
  • Maintain clear visibility for security teams monitoring the boundary.
  • Meet anti-climb, anti-cut, and anti-tool penetration

TdefenseOACH

• • Conducted a full site survey across the mountainside to map gradient, rock outcrops, and access routes.
  • Specified galvanized high-security mesh for long-term coastal performance.
  • Poured a continuous reinforced concrete plinth along the base of the fence to seal ground-level gaps.
  • Anchored posts into deep concrete footings, with rock fixings used where required.
  • Stepped panels up the slope to follow the terrain while keeping a continuous, secure line.
  • Fitted a razor coil along the top of the fence as an added deterrent.
  • Installed stainless steel security fasteners and anti-tamper clamp bars on every panel.
  • Built and fitted a custom access gate to match the main fence's security rating.
  • Worked under strict site access protocols suited to a defence facility.
