A double-jointed fence is a type of fencing structure designed to provide enhanced security, durability, and stability. The term “double-jointed” refers to the presence of two horizontal support bars, or rails, at each joint or connection point between vertical posts. These additional rails contribute to the fence’s strength, making it suitable for environments requiring robust barriers, such as industrial sites, high-security areas, or property boundaries.
Features of a Double-Jointed Fence
- Enhanced Strength: The double-jointed structure increases the fence’s resistance to force and impact, making it harder to breach or deform.
- Durability: The design usually incorporates high-quality materials like galvanized steel or treated iron, making the fence resistant to rust, corrosion, and environmental wear.
- Security: The close spacing of the vertical bars, combined with the double horizontal support rails, minimizes gaps and makes climbing or cutting through more difficult.
- Aesthetics: Despite its industrial application, double-jointed fences can have a sleek appearance and may be coated in various colors to suit the surrounding environment.
- Customizable Dimensions: Depending on the application, the height, width, and spacing between bars can be customized.
Dimensions Table for a Standard Double-Jointed Fence
| Component | Dimension | Description |
|---|---|---|
| Overall Height | 1.8m – 3.0m | The typical height range; can be customized based on security requirements. |
| Vertical Bar Diameter | 16mm – 25mm | The thickness of the vertical bars, which can vary based on the desired strength and rigidity. |
| Horizontal Rails | 40mm x 20mm (x2) | Double horizontal rails made of rectangular tubes for increased stability and strength. |
| Spacing Between Bars | 100mm – 150mm | The distance between each vertical bar; closer spacing offers higher security. |
| Post Size | 60mm x 60mm – 80mm x 80mm | The size of the square posts that hold the panels in place; affects overall stability. |
| Post Spacing | 2.5m – 3.0m | The distance between posts; longer spacing reduces the number of posts required. |
| Foundation Depth | 600mm – 900mm | The depth of the foundation for the posts, typically set in concrete for maximum stability. |
| Coating | Powder Coating / Galvanized | Surface treatment to prevent corrosion and enhance appearance. |
Application and Customization
Double-jointed fences are ideal for various applications:
- Industrial Facilities: Heavy-duty fencing for factories, warehouses, and production sites.
- Perimeter Security: Secure fencing for restricted areas, military zones, or critical infrastructure.
- Commercial Spaces: Used in settings like schools, sports complexes, and commercial buildings.
Customization options include:
- Height and Length Adjustments
- Color Finishes
- Additional Security Features: Razor wire, spikes, or anti-climb paint.
A double-jointed fence provides a combination of security and aesthetics, making it a versatile option for various high-security environments.
