When security is an issue and you need to keep things safe and protected, use razor wire.

Razor wire is a coiled metal strip with very sharp edges whose purpose is to prevent passage by humans. Razor wire is much sharper than the standard barbed wire, and the multiple blades of a razor wire fence are designed to inflict serious cuts on anyone attempting to climb through or over a fence.

In any event, razor wire has a strong psychological deterrent effect in terms of security. In many high-security applications,razor wire replaced barbed wire, because barbed wire could be defeated relatively quickly.  Conversely, penetrating razor wire barriers without tools is very slow and difficult.

Needless to say, razor wire can be very dangerous stuff.  S&S Fence, however, has decades of experience in properly installing razor wire and is a recognized leader in the field of security fencing.
