D-Welded Mesh

Name: D-Welded Mesh
Brand: D-FENCE

The strain-gauge sensor is the connector that holds each panel, so any climb or cut changes the load and raises an alarm.

Black double-wire welded-mesh fence with Y-post outriggers running through a pine forest site

A mesh fence that feels every attack.

In D-Welded Mesh the strain-gauge sensor is the connector between the mesh panel and the sensor post. Unlike systems added to a fence, such as vibration cables, it is an integral part that holds the panels.

Built into the fence

The sensor is the panel connector, not an add-on cable: nothing to bypass, nothing to snag.

Tells threat from weather

The controller recalibrates constantly and uses a self-adapting algorithm to filter wind and weather.

Any panel, any length

Panels up to 100 kg, unlimited fence length, zones of 12–24 m set to your site.

A controller constantly calibrates the sensor signals and runs a self-adapting algorithm that tells a real attack from wind and weather. Posts are 60 × 60 mm and 2 m high or more, and panels can weigh up to 100 kg.

Used along railways in Germany, at airports, ports, campuses and homes: anywhere the fence has to look ordinary and still report every climb or cut.

From the first touch to the right response.

Sensor as connector
Each mesh panel hangs on stainless strain-gauge sensors in the sensor posts.
Load change
A climb or cut adds 25 kg or more above the panel's own weight.
Self-adapting controller
Signal processing in the posts separates real attacks from wind and weather.
Integration
Dry contact or RS232 to the alarm system, CCTV, mobile control or D-Command Control.
