Looking through a razor-mesh fence at a hillside site, the diamond pattern of welded blades in the foreground

Stop climbers and cutters at the barrier.

D-Razor Mesh is made of small, sharp blades welded together into a diamond-shaped mesh on a high-strength galvanised steel core wire. It is built for high-security sites where climbing and cutting must be stopped at the barrier.

01

Hard to climb, hard to cut

Razor blades welded into a diamond mesh on a high-strength galvanised core wire.

02

Every attempt reported

Strain-gauge sensors and controllers watch the fence 24/7 and flag the attacked zone.

03

Sized to the risk

Heights from 1.2 m to 2.4 m and above; mesh size and blade profile to specification.

The mesh works with D-FENCE's field-proven strain-gauge sensors and electronic controllers, so every attempt on the fence is reported to the control room, 24/7.

Mesh size, blade profile, coating and height are chosen for the site: prisons, military bases, airports and industrial facilities.

From the first touch to the right response.

  1. Razor mesh barrier

    Welded razor-blade mesh panels on steel posts, on the ground, on walls or on an existing fence.

  2. Strain-gauge sensors

    Sensors on the posts feel the force of a climb or cut.

  3. Controller

    Proprietary algorithms decide in real time; each zone covers up to 90 m.

  4. Alarm out

    Dry contact or RS232 / RS485 to your control room, cameras and alarm system.
