Double-Bar Mat Fences: Durability and Functional Property Boundary
Double-bar mat fences represent a technically sophisticated solution for the permanent enclosure of private properties, commercial areas, and public facilities. They are characterized by high static stability and torsional rigidity, making them a preferred choice for property protection. Kirchberger Metall's systems are based on proven fence technology and are designed for a long service life with minimal maintenance. Due to their modular design, these fence systems can be precisely adapted to different terrains and security requirements.
Technical Specifications and Load Capacity: Importance of Wire Gauges
The load capacity and mechanical resistance of a double-bar mat fence are primarily defined by the chosen wire gauges. These are usually indicated in numerical triplets, such as 5:4:5, 6:5:6, 6:6:6, 6:8:6, or 8:6:8. The meaning of these figures is technically defined:
- The first and third numbersindicate the diameter of the two horizontal bars in millimeters.
- The middle numberindicates the diameter of the vertical bar in millimeters.
The general impact of these dimensions on the fence system is directly proportional to the material thickness: The higher the selected wire diameters, the higher the static load capacity, form stability, and resistance to mechanical influences.
While lighter variants such as 5:4:5 or 6:5:6 are often used in private areas for classic fencing, heavy-duty versions like 8:6:8 offer maximum stability for industrial applications or locations with increased security needs.
A standard fence element has a width of 2510 mm and a mesh size of 50 x 200 mm. Available heights range from 800 mm to 2400 mm, with increments of 200 mm. A technical detail is the approx. 30 mm long fence spikes, which can be mounted pointing upwards or downwards depending on security requirements or aesthetic preference.
Corrosion Protection and Surface Finishing
To ensure a service life of several decades, all fence components undergo a multi-stage finishing process. The basis is hot-dip galvanizing according to DIN EN ISO 1461, which effectively protects the steel from oxidation and rust. An optional subsequent powder coating further enhances corrosion protection and allows for color integration into the surroundings. Common standard colors include anthracite (RAL 7016) and moss green (RAL 6005). These coated surfaces are maintenance-free, UV-resistant, and resistant to mechanical influences.
Accessories and Extension Options for Privacy Screens
The functionality of a double-bar mat fence can be extended by specific accessories. An essential element is privacy strips made of weather-resistant plastic, which are woven into the meshes of the fence mats. This transforms the transparent mesh fence into an opaque barrier that provides privacy and also functions as a windbreak. Various systems such as cover strips or clamping brackets are available for attaching the fence mats to the posts. Further accessories such as aluminum post caps, base plates for mounting on concrete surfaces, and integrated fence lighting can be configured as required.
Planning and Professional Installation Service
The implementation of a fence project can be done either through pre-configured complete packages or by selecting individual elements. Complete sets already include all necessary fence posts and accessories for the chosen fence length. Regarding installation, two methods are available: embedding the posts in concrete for maximum stability, or bolting them down with base plates on existing foundations or paved areas. In addition to expert advice and planning, Kirchberger Metall offers an installation service by qualified specialists to guarantee the standard-compliant setup and alignment of the fence system.
