g* Acombination of sharp razor and hiqh-tensiie wire
has made Razor Barbed wire an ideal fencing
material for protection pirposes. The cut-throat
razors mounied at the top of the wall will effectively
stop the unwelcome intruders from entering by
force. Other than the worldwide use at military base,
jail and other government units, as crime rate
increases everywhere, i t has recently become very
popular for private property owners t o accept the
razor type as an effective protection fencing. Two
majortypes, Crosss and Straught, may be selected t o
meet the users' financial budget and installation
requirement, installation planning services are also
available t o meet our customers'individual needs.
