Double wire mesh industrial fencing, you should pay attention to this when buying your fence!

by Karl Marx, rotec Berlin | Jun 28, 2024 | General, Home, Metalworking, Products, Security fences | 0 |

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.
