This is because valuable materials are often stored outdoors, and at the same time, sites are frequently unmanned at night. This increases the risk, which is why perimeter protection is needed that both deters intruders and triggers an alarm. This is precisely where security fencing and high-security fencing complement each other when viewed as a single system.

The popularity of double wire mesh as a fencing system in Europe is undisputed. This popularity results from the robust construction, the fact that they are largely maintenance-free and their high cost-effectiveness. Despite a higher initial investment compared to wire mesh fences, the investment pays off in the long term. Traditionally, the double wire mesh has been manufactured over four decades with a mesh size of 50×200 mm, two cross wires made of 8 mm round steel and a vertical bar made of 6 mm round steel. After production, the mats are hot-dip galvanized in a full bath, making them particularly robust and durable - a hallmark of rotec quality.

At the time, my YouTube video creation skills were still in their infancy, making this movie one of my first projects in this area.
