Concertina fencing is widely used for high-security applications such as industrial areas, warehouses, agricultural lands, government facilities, and boundary protection. Proper height and spacing are critical factors that determine the effectiveness, durability, and security performance of the fencing system.
Incorrect spacing or insufficient height can reduce security and make the fence vulnerable to intrusion. This guide explains the recommended measurements and best practices for installing concertina fencing.
Why Height and Spacing Matter in Concertina Fencing
Proper installation dimensions provide:
Maximum intrusion prevention
Strong structural stability
Better coil tension and durability
Professional appearance
Long-term performance
Recommended Height for Concertina Fencing
The ideal height depends on the security level required and the installation location.
| Security Level | Recommended Height |
|---|---|
| Residential Boundary | 5 – 6 feet wall + concertina |
| Commercial Property | 7 – 8 feet total height |
| Industrial Security | 8 – 10 feet |
| High-Security Zones | 10 – 12 feet or more |
| Ground Barrier Installation | 3 – 5 feet coil diameter |
Higher fences provide better deterrence and are harder to climb or breach.
Concertina Coil Diameter Guidelines
Concertina wire comes in different coil diameters, which influence overall fence height and coverage.
| Coil Diameter | Typical Use |
|---|---|
| 450 mm | Residential & low security |
| 600 mm | Commercial areas |
| 730 mm | Industrial fencing |
| 900 mm | High security installations |
| 980 mm | Military & maximum security |
Larger diameters provide better security but require stronger support structures.
Post Spacing Guidelines
Correct spacing between fence posts ensures proper tension and prevents sagging.
| Installation Type | Recommended Post Spacing |
|---|---|
| Chain Link Fence with Concertina | 2.5 – 3 meters |
| Wall Top Installation | 2 – 2.5 meters |
| Steel Frame Structure | 3 meters |
| Ground Barrier Installation | 1 – 1.5 meters |
Closer spacing increases strength and security.
Spiral Clip Spacing for Concertina Coils
Concertina coils are connected using metal clips to maintain shape and stability.
| Coil Type | Clip Spacing |
|---|---|
| Single Coil | 3 – 5 clips per spiral |
| Cross Concertina | 5 – 7 clips per spiral |
| High Security Coil | 7 – 9 clips per spiral |
More clips provide better rigidity and durability.
Factors Affecting Height and Spacing Decisions
Several factors influence installation measurements:
Security level required
Terrain and soil condition
Wind exposure
Fence material strength
Coil diameter
Installation method (wall, fence, ground)
Budget constraints
Proper planning ensures optimal performance.
Installation Best Practices
Use galvanized or PVC-coated concertina wire
Ensure strong post foundations with concrete
Maintain uniform coil tension
Avoid excessive spacing between supports
Install angled extensions for extra security
Professional installation significantly improves effectiveness and lifespan.
Common Installation Mistakes to Avoid
Too much spacing between posts
Low fence height for high-risk areas
Weak support structures
Poor coil tension
Using low-quality materials
Avoiding these mistakes ensures reliable security.
Benefits of Proper Height and Spacing
Increased security effectiveness
Longer fence lifespan
Reduced maintenance costs
Better resistance to environmental forces
Professional and strong appearance
Conclusion
Height and spacing are critical components of successful concertina fencing installation. Choosing the correct coil diameter, maintaining proper post spacing, and ensuring adequate fence height significantly improves security performance.
