A prison perimeter project required a high-security fencing system around restricted areas, service zones, access points, and the main external boundary.
The customer needed a fence that was difficult to climb, strong enough for a permanent security perimeter, and open enough for surveillance teams to maintain clear visibility.
For this project, BDFENCE supplied a 3-meter-high 358 Anti-Climb Fence system together with steel posts, security fixings, pedestrian gates, vehicle gates, and installation accessories.
Because the fence height reached 3 meters, the project required more careful coordination than a standard perimeter fence. Panel dimensions, post strength, fixing points, gates, and surface protection all had to work as one system.

What Did the Prison Project Require?
The project needed more than a simple boundary fence.
The perimeter formed part of the site’s main security layer. Therefore, the fence had to support several functions at the same time.
The key requirements included:
- Strong anti-climb characteristics
- 3-meter perimeter height
- Clear visibility for CCTV and patrol teams
- Secure pedestrian access
- Controlled vehicle access
- Reliable outdoor performance
- Consistent installation across long fence sections
The customer also wanted the fence, posts, gates, and security fittings to come from one coordinated supply source.
Why Was 358 Anti-Climb Fence Selected?
The prison perimeter required a mesh design that offered fewer conventional hand and foot holds than standard large-opening fencing.
The 358 mesh configuration uses a narrow opening of approximately 76.2 × 12.7 mm.
As a result, the fence presents a more difficult climbing surface while still allowing security teams to see through the perimeter.
That combination made 358 Fence suitable for this correctional security application.
Why Did the Project Use a 3m Fence Height?
Height formed an important part of the prison perimeter strategy.
A 3-meter fence created a taller physical barrier than standard commercial fencing. However, increasing the height also changed the structural requirements of the system.
The project therefore needed:
- Longer fence panels
- Heavy-duty steel posts
- More secure fixing points
- Suitable gate frames
- Careful post alignment
For this reason, BDFENCE treated the 3m fence as a complete engineered perimeter package rather than simply a taller mesh panel.
Challenge 1: Supporting 3m-High Fence Panels
The taller the fence, the more important the post and connection system becomes.
A 3m panel places greater demand on the supporting structure than a lower fence section.
BDFENCE Solution
BDFENCE coordinated the panel and post system according to the confirmed project requirements.
Our production checks focused on:
- Panel height and width
- Post dimensions
- Post wall thickness
- Fixing positions
- Panel flatness
- Weld consistency
As a result, the installer could work with a more consistent panel-to-post connection across the perimeter.
Challenge 2: Anti-Climb Performance Without Blocking Visibility
The prison required a strong security boundary, but a solid wall was not preferred in every section.
Security teams still needed to monitor movement through CCTV and direct observation.
BDFENCE Solution
The narrow 358 mesh created a difficult climbing surface while maintaining open sightlines.
Therefore, security teams could continue to observe areas beyond the fence without losing the benefit of a high-security welded mesh barrier.
Challenge 3: Securing Access Points
A prison perimeter is only as strong as its controlled openings.
The project required separate access points for staff, service vehicles, maintenance teams, and authorized operations.
BDFENCE Solution
BDFENCE supplied pedestrian and vehicle gates that matched the main 358 Fence system.
The gate design coordinated:
- Fence height
- 358 mesh infill
- Gate posts
- Hinges
- Locking hardware
- Adjacent fence connections
In addition, the matching mesh helped maintain a consistent security appearance around the perimeter.
Challenge 4: Security Fittings Had to Match the System
High-security fencing depends on more than panels and posts.
The project also required secure connection components.
These included:
- Security clamps
- Fixing bars or plates
- Anti-tamper bolts
- Security nuts
- Washers
- Post caps
- Gate hardware
BDFENCE Solution
BDFENCE prepared the fittings according to the confirmed fence system instead of treating them as separate accessories.
We also checked the quantities before shipment. Therefore, the customer received a more complete installation package.
What Did BDFENCE Supply?
| Component | Purpose |
|---|---|
| 3m 358 Fence Panels | Main anti-climb perimeter barrier |
| Heavy-Duty Steel Posts | Support for tall fence sections |
| Security Fixings | Panel-to-post connection |
| Anti-Tamper Fasteners | Secure fence assembly |
| Pedestrian Gates | Controlled personnel access |
| Vehicle Gates | Controlled vehicle access |
| Post Caps and Hardware | System completion |
Manufacturing the 358 Fence Panels
BDFENCE manufactured the welded mesh panels according to the confirmed 358 configuration.
During production, our team checked:
- Wire diameter
- Mesh opening
- Panel dimensions
- Weld condition
- Panel straightness
- Surface quality
For a 3m-high project, panel consistency becomes especially important because small dimensional differences are more visible during installation.
Surface Protection for Long-Term Outdoor Use
The perimeter would remain outdoors throughout its service life.
Therefore, the project required a corrosion-protection system suitable for long-term exterior use.
BDFENCE supplied galvanized and powder-coated components according to the confirmed project requirement.
The finish applied across the main visible steel parts, including:
- 358 Fence panels
- Steel posts
- Security gates
- Visible connection parts
This helped create a more uniform perimeter appearance while supporting outdoor durability.
Quality Control Before Shipping
For a prison fence project, BDFENCE checked the complete system rather than focusing only on the mesh panels.
| Component | Inspection Focus |
|---|---|
| 358 Fence Panels | Mesh opening, wire diameter, dimensions, welds and flatness |
| Steel Posts | Dimensions, wall thickness, length and straightness |
| Security Fixings | Type, quantity and connection match |
| Pedestrian Gates | Frame size, hinges and hardware |
| Vehicle Gates | Frame alignment, opening movement and gate hardware |
| Surface Finish | Visible coating condition and consistency |
As a result, the shipment arrived as a coordinated security fence package rather than a collection of unrelated parts.
Packaging for a High-Security Fence Project
The 3m panels required careful handling because of their size.
BDFENCE stacked and secured the fence panels for transport. Meanwhile, we bundled posts separately and packed the security fittings by type.
Gate components also received separate identification.
This approach helped the contractor identify materials more easily after delivery and reduced unnecessary sorting on site.
Installation Approach
The local contractor followed the approved perimeter layout.
The main installation sequence included:
- Confirm the fence line and gate locations
- Install the heavy-duty steel posts
- Position the 3m 358 Fence panels
- Fix the panels with security fittings
- Install pedestrian and vehicle gates
- Check the final fence alignment
- Inspect all key connections
Because the panels, posts, gates, and fittings were supplied as one system, the installer could follow a consistent assembly method across the project.
Project Result
After completion, the prison perimeter gained a taller and more security-focused boundary system.
| Security Requirement | Project Result |
|---|---|
| Anti-Climb Perimeter | Narrow 358 mesh configuration |
| Fence Height | 3,000 mm security barrier |
| Monitoring | Open mesh preserved sightlines |
| Personnel Access | Controlled pedestrian gates |
| Vehicle Access | Matching security vehicle gates |
| Installation | Panels, posts and security fittings worked as one system |
Most importantly, the completed perimeter combined physical security with the visibility needed for daily prison operations.
Why 358 Fence Is Often Considered for Prison Perimeters
Correctional facilities place greater demands on fencing than ordinary commercial projects.
The perimeter may need to control movement, support surveillance, reduce climbing opportunities, and integrate secure access points.
358 Fence can support these requirements because it offers:
- Narrow mesh openings
- Rigid welded construction
- Good visibility
- High fence configurations
- Security gate integration
- Compatible anti-tamper fittings
However, the final fence specification should always follow the approved correctional facility design and security requirements.
