How to Install 358 Mesh Fence

358 mesh fence, often called anti-climb fence or prison mesh, is one of the most secure fencing systems available. With its small apertures (76.2mm x 12.7mm) and strong welded steel wires, it resists cutting and climbing, and it is ideal for prisons, airports, military bases, and other high-security areas.

Installing a 358 mesh fence is a technical process that requires precision, proper tools, and the right sequence of steps. In this guide, we will walk you through everything you need to know to install a 358 mesh fence effectively.

Tools and Materials You Will Need

1. 358 mesh fence panels

2. Steel posts (square or rectangular, galvanized or powder-coated)

3. Concrete mix (for securing posts)

4. Brackets, clamps, or fixing clips

5. Bolts, nuts, and washers (anti-tamper type recommended)

6. Level and measuring tape

7. String line and chalk

8. Power drill and wrench

9. Protective equipment (gloves, safety glasses, boots)

Step 1: Plan the Fence Layout

A successful installation starts with careful planning:

 Mark the boundaries – Use stakes and string line to outline where the fence will go.

 Measure accurately – Take into account panel width (commonly 2.5m or 3m) to calculate the number of posts and panels needed.

 Check the ground – Ensure the terrain is suitable. Sloped areas may require stepped or raked installation.

Step 2: Install the Fence Posts

The posts are the backbone of the fence:

 Dig post holes – Each hole should be about one-third the post length deep, typically 600–800mm.

 Set the posts in concrete – Mix and pour concrete into the hole while holding the post upright. Use a level to ensure it is perfectly vertical.

 Align the posts – Use the string line to maintain a straight line across all posts.

 Allow curing time – Wait at least 24 hours for the concrete to harden before attaching panels.

 Tip: For maximum strength, use galvanized or powder-coated posts to resist rust and corrosion.

Step 3: Attach the 358 Mesh Panels

 Once the posts are secure, you can install the mesh panels:

 Position the panel – Place the panel against the post so that it is level with the ground.

 Secure with brackets/clamps – Fix the panel to the post using clamps or fixing brackets. Start at the top, then secure the bottom, and finally the middle.

 Tighten connections – Use anti-tamper bolts and washers to prevent unauthorized removal.

 Check alignment – Ensure the panel is straight and flush with the posts.

Step 4: Continue Panel Installation

Repeat the process – Move along the fence line, installing one panel at a time.

 Maintain tension – Keep each panel tight against the previous one for a seamless line.

 Handle corners carefully – Use corner posts or adjust brackets for a clean transition.

Step 5: Finishing Touches

Inspect joints and fasteners – Make sure every panel is securely fixed.

 Add gates if required – Install high-security gates using the same mesh style for continuity.

 Apply protective coating – If panels were cut or welded on-site, apply zinc spray or paint to prevent corrosion.

Practical Tips for a Professional Installation

 Always double-check measurements before fixing posts permanently.Use anti-tamper hardware to maintain high security.On uneven ground, use stepped installation rather than forcing the panel to bend.For extra security, install barbed wire or razor coils above the 358 mesh fence.

Conclusion

Installing a 358 mesh fence requires careful planning, precise alignment, and secure fixing. When done correctly, it provides unmatched protection and durability for high-security sites. By following these steps and tips, you can ensure that your 358 mesh fence not only looks professional but also performs its critical role—keeping your property safe.
