Concertina Wire + Welded Mesh Panel + Y Fence Post = Anti Cut and Anti Climb High Security Fence System

Concertina Wire, is made by galvanized steel plate or stainless steel plate punched into certain forms then attached to the steel wire in sharp angle to form the blades. Sharp blades form a kind of " concertina" by buckles / clips, when used along fencing tops, render a frightening anti climbing effect for the perimeters and borders.

Features of Concertina Razor Wire:
Beautiful appearance;
Economic cost;
Easy installation;
Good frightening result.

Security Fence System of Welded Mesh Panel Topped with Concertina Wire Coils

A typical high security fencing system is composed with finger proof 358 weld mesh panel and anti climbing concertina razor barbed wire tops. The security fencing tops are commonly mounted above Y posts.

Fencing system of galvanized steal and stainless steel wire.
Concertina wire coils for fence security installation.
Quality complies with ASTM F-1910.
