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.

In recent years, various manufacturers have started to produce double wire mesh with ever thinner wires. Today, there are double wire meshes on the market where the horizontal wires are only 6 mm thick and the vertical wires are 5 mm thick. For comparison: A double bar mat (2030 x 2510 mm) with 8/6/8 wires weighs approx. 40 kg per piece, the thinner version with 6/5/6 wires only 29 kg - a saving of 11 kg of steel per mat.

Visually, these mats are almost indistinguishable to the layman. However, the thinner double rod mats do not offer the same robustness and stability as their thicker counterparts. Depending on how stable and durable you want your fence to be, you should take these differences into account when making your purchase decision.

Another important consideration when purchasing double wire mesh panels is the type of surface treatment. The traditional method, in which the mesh panels are made from raw iron and then hot-dip galvanized in a full bath, offers optimum corrosion protection. This method ensures that the zinc coating remains intact and protects the mesh from rust in the long term.

However, there is also a more cost-effective process in which the wires are galvanized during production (strip galvanized wire). The disadvantage of this process is that the zinc coating burns off when the crossing points are welded together, which impairs the corrosion protection. Even subsequent powder coating cannot completely remedy this. Depending on the effects of the weather, double rod mesh can rust at the welded joints, sometimes even within the warranty period.
