Concertina Wire is a type of razor barbed wire fixed in sprial or "concertina" shape ideal for High Security Fencing Tops.
Concertina Wire Features
1, Concertina wire is extremely durable with hot dipped zinc coating meeting international standard for corrosion protection;
2, Concertina wire provides high security as the wire is
fabricated from high tensile wire which cannot be cut
with standard cutting tools such as utility knife or saw blades while the high tensile steel wire offers high strength and flexibility for easy installation;
3, Concertina wire is
fabricated in coils that can extended at least 50 feet (15.2 m) without permanent
distortion, can be mobile fencing barriers and used repeatedly;
4,
Concertina Wire is supplied in rolls and formed of a multitude of
razor-sharp barbs at close interval, forming a high security anti climbing tops for a variety of steel fencing panels.
