What is Concertina Wire?
Concertina Wire is coiled razor wire in single and cross-concertina formats — a rapid-deployment, high-security barrier for defense, correctional and critical-infrastructure perimeters. It is best suited to defense & border security, correctional facilities, high-security perimeters. Medvaan confirms the gauge, dimensions and coating against the application before dispatch.
See specificationsEngineered for the load it will actually see
Concertina wire earns its place at the top of the security tier because of how it fails an intruder, not how it holds a load: a coiled core wire carrying stamped razor-sharp blades at fixed intervals, expandable into a long barrier from a compact transport coil.
We supply both single-coil and cross-type (double-coil, cross-clipped) formats. Cross-concertina holds its shape without picketing in the middle of a run, which matters when a barrier needs to go up fast and stay upright without a full support structure behind it.
What sets Concertina Wire apart
Single or cross-coil format
Cross-type construction holds shape without mid-run support.
Fixed blade spacing
Razor blades stamped and clipped at consistent intervals.
GI or stainless steel core
Core wire selectable for corrosion environment and service life.
Rapid-deployment coil
Expands from a compact transport coil to a long barrier run.
Coupling accessories
Concertina clips and coupling hardware for continuous runs.
Multiple coil diameters
Diameter selected against required barrier height and deterrence level.
