Introduction to 358 high security anti-climbing fence

358 high-security anti-climb fence, also known as "358 net guardrail" or "prison net", is a security fence widely used in high-security areas such as prisons, military facilities, and critical infrastructure sites. The name "358" refers to its dimensions: 3" x 0.5" x 8 gauge, which equates to approximately 76.2mm x 12.7mm x 4mm.
Main features and characteristics:
Mesh Design: The fence features a tight mesh pattern with smaller openings, making it difficult for intruders to climb or cut through. The mesh design provides a high level of visibility for effective monitoring of secure areas.
Climbing Resistance: The small size of the grid and lack of hands or footholds make it challenging for individuals to climb the fence. This blocks unauthorized access and enhances security.
Cut Resistant: The wire used in fencing is typically made from high-strength steel that resists erosion from cutting tools like bolt cutters and wire cutters. This helps prevent violations and vandalism.
Durability: The materials used in the 358 High Security Fence are corrosion-resistant and designed to withstand harsh environmental conditions, ensuring long-term durability and reliability.
Top Security Enhancements: The top of your fence can optionally be equipped with additional security features such as razor wire, barbed wire, or rotating anti-climb spikes to further deter intruders.
Overall, the 358 High Security Anti-Climb Fence is an effective solution for securing sensitive locations, providing strong protection against unauthorized access, intrusion and vandalism.
Next, I will introduce the 358 fence in terms of wire, mesh size, surface treatment method, installation method, etc.
silk thread：We have two wire options for electric welding: bare wire and galvanized wire.

Note: The selection of these two types of wires will correspond to the later surface treatment. The bare wire is suitable for later hot-dip galvanizing treatment, and the solder joints will also be protected by a zinc layer. This type has the best quality and the highest price.
Galvanized wire is suitable for anti-corrosion treatment in the later stage, such as powder spraying and powder dipping. The price is low and the quality is good.
Mesh size：There are also two sizes of mesh we are welding now.

Note: The difference between standard sizes and non-standard sizes is mainly a matter of cost. There is not much difference in safety and anti-climbing properties, and there is no difference in production process.
Surface treatment:There are three types of surface treatments: hot-dip galvanizing, powder coating, and powder coating.

Surface hot-dip galvanizing anti-corrosion treatment method


Surface powder coating anti-corrosion treatment method


Surface powder dipping anti-corrosion treatment method
Note: The difference between the above three processing methods is mainly in cost control.
Hot-dip galvanized wire must be produced using bare wire, which has the highest cost, the best quality, and the best durability.

The powder coating treatment method is produced using galvanized lines. The cost is intermediate, the quality is also very good, the durability is good, and the appearance color can be selected.

The powder hot dip molding treatment method uses galvanizing lines to produce dip molding. The amount of attached plastic is high and the wire diameter is thick. If the customer requires a wire diameter after molding, this is the lowest cost, because the thick plastic attached to the wire can meet the usage requirements and the lowest cost. Appearance color can be chosen

How to install the mesh:There are two general methods: claw fixation and flattened steel fixation. All fixation methods are anti-theft treated.




The installation method of the claws is not necessarily this way. The uprights can be installed against the holes, and long screws can also be fixed. It is mainly for anti-theft and stability.



The installation method of flat steel is also a very common installation method. Compared with claws, the installation is complicated, the cost is high, and the installation speed is slow.


358 anti-climbing fences are basically of these types. I mainly introduce the direction of cost and the use effect is not much different. Depending on the needs of the customer, they can be customized and produced according to the requirements.
