A variety of Fence Panels can be used for High Security Fencing, for Customers Options:
Welded Mesh Panels: Known for their rigidity and strength.
358 Anti-Climb Fence Panels: Named after its measurements (3" x 0.5" x 8 gauge), designed to be finger-proof, toe-proof, and almost impossible to grip, making it difficult to climb.
Chain Link Fencing: Made by weaving of steel wires into a diamond pattern, chain link fence can be used for high security with toppings like barbed or razor wire.
Palisade Fencing: Comprised of vertical steel pales with pointed tops, palisade fence is especially difficult to climb or cut.
Expanded Metal Fencing: Produced by stretching metal sheets, it is highly durable and offers good visibility.
