Single layer security fence only forms basic isolation effect and cannot stop intentional climbing and crossing behavior. Adding barbed wire on the top of fence forms dual protection layer to eliminate hidden safety risks of important storage and production sites.

Two mainstream barbed wire types apply to security fence matching including blade barbed wire and twisted barbed wire. Blade barbed wire owns sharp cutting structure for high security prison and chemical warehouse fence. Ordinary twisted barbed wire suits general factory security fence with medium protection demand.

Barbed wire installed on security fence top stays exposed to wind and rain all year round. Hot galvanized barbed wire avoids rust breakage under long term outdoor environment. Plastic coated barbed wire reduces surface scratch risk for personnel passing beside security fence without losing anti crossing function.

Special fixing brackets match barbed wire and security fence stand column firmly without loose displacement under strong wind. Multi layer spiral winding layout of barbed wire forms dense barrier above security fence top to block climbing paths completely. The installation structure does not damage the original coating of security fence.

For ultra high security demand sites, barbed wire cooperates with anti climb fence to form triple anti intrusion protection. Dense grid anti climb fence blocks basic climbing movement, and multi loop barbed wire sets up secondary obstacle on the top, which is widely recognized for perimeter protection of dangerous goods storage areas.
