Double wire fence specification for Germany
In Germany, double wire fences (also known as "Doppelstabmatten" fences) adhere to specific standards and requirements, focusing on durability, rigidity, and aesthetics. Here’s a general specification outline commonly followed for these fences:
1. Wire Gauge and Dimensions
Horizontal Wires: Typically 6 mm or 8 mm in diameter; two parallel wires per row.
Vertical Wires: Generally 5 mm or 6 mm in diameter; spaced every 50 mm.
Mesh Size: Standard grid pattern with a 50 mm x 200 mm spacing (vertical x horizontal).
2. Panel Sizes and Heights
Height Options: Common heights include 630 mm, 830 mm, 1030 mm, 1230 mm, 1430 mm, 1630 mm, 1830 mm, 2030 mm, and 2430 mm.
Panel Length: Typically 2,500 mm (2.5 meters).
3. Materials and Coating
Steel Construction: Panels and posts are made from high-quality, galvanized steel to prevent rust and corrosion.
Coating: Fences are hot-dip galvanized and then powder-coated for added durability and color options. Popular colors in Germany are green (RAL 6005), anthracite (RAL 7016), and black (RAL 9005).
4. Posts and Fastenings
Post Dimensions: Usually 60 x 40 mm or 60 x 60 mm for extra stability.
Mounting: Posts are set at intervals of 2,500 mm to align with panel length, using either bolted or clamp fixings.
Base Plates or Ground Installation: Posts may come with base plates for concrete mounting or be embedded directly into the ground.
5. Security Enhancements
Optional Barbed or Razor Wire: Can be added for high-security areas.
Anti-Climb Features: Panels with smaller mesh spacing near the top or angled extensions for additional deterrence.
6. Standards Compliance
German and European quality standards are generally adhered to, such as DIN EN ISO 1461 for galvanizing and DIN EN 10244 for coating.
