358 anti climbing fence

Materials and Protection: Cold drawn Q235 low-carbon steel wire with a tensile strength of ≥ 500MPa is used, which has undergone triple anti-corrosion treatment of galvanizing, dipping and spraying. It has undergone salt spray testing for over 1000 hours without corrosion. The PVDF coating has a lifespan of 25 years in high salt spray environments along the coast, effectively resisting cutting and climbing.

Structural strength: Reinforced with rectangular steel tube frame and embedded with anchor bolts, capable of withstanding wind loads of level 8 and seismic impacts of degree 8; Modular installation (bolt+welding process) supports daily laying of 200 meters and is compatible with concrete bases or quick installation brackets.

Size and appearance: Height of 1.5-4 meters (4-meter version specifically for airports/borders), board width of 2-3 meters, supporting non-standard customization; The colors include standard colors such as dark green, gray white, police blue, desert yellow, etc., and can be customized with camouflage or enterprise exclusive colors, balancing concealment and recognition needs.

The fence restricts grip space through high-density grids (76mm × 12mm), and can be equipped with anti climbing frames or knife ropes at the top to form three-dimensional protection. Combined with electronic fences, it achieves dual security protection and is suitable for high-risk scenarios such as military, judicial, energy, and transportation.

As a benchmark product for high safety scenarios, the technical parameters and performance advantages of the 358 anti climbing fence can be comprehensively presented through the following structured analysis:

358 (12)


Core parameters and protection principles


Naming logic: 3-inch (76mm) spacing between horizontal bars+0.5 inch (12mm) spacing between vertical bars+8 gauge steel wire (diameter 4mm), to construct a high-density grid structure that directly blocks invasive behaviors such as climbing and cutting.


Anti climbing mechanism:76mm × 12mm fine mesh restricts finger grip space, combined with 3-5mm shear resistant steel wire to form a physical barrier;


The top can be equipped with a Y-shaped anti climbing frame or a snake belly type knife and stab rope to construct a three-dimensional protection system;


Using cold drawn Q235 low-carbon steel wire (tensile strength ≥ 500MPa), it has undergone triple anti-corrosion treatment of galvanizing, plastic immersion, and spray coating. It has undergone salt spray testing for over 1000 hours without red rust. The PVDF fluorocarbon coating has a lifespan of 25 years in high salt spray environments along the coast.



Structural performance and customization capability



Stability design:


The frame is reinforced with rectangular steel pipes and embedded with anchor bolts, which can withstand wind loads of level 8 and impacts from seismic zones of level 8;


The modular installation system (bolt+welding dual process) supports rapid assembly of single boards, with a daily laying distance of up to 200 meters, and is compatible with concrete bases or quick installation brackets.



Customization of size and appearance:


The height range is 1.5-4 meters (the super high-rise 4-meter version is specifically designed for airport/border isolation), the standard board width is 2-3 meters, and non-standard size customization is supported;


The color system includes standard colors such as dark green, gray white, police blue, desert yellow, etc. It can be customized with camouflage coating or enterprise exclusive colors to balance concealment and recognition needs.

Application scenarios and cost-effectiveness



Adaptation to high-risk scenarios:


Military fortresses (ammunition depots, command centers), judicial systems (prisons/detention centers), energy facilities (power plants/oil depots), transportation hubs (airport/station isolation zones), high-end properties (villa areas/industrial parks);


Compared to peach shaped fences, 358 fences have better anti climbing performance, but the cost is higher, and the specifications need to be selected according to the risk level (for example, in high-risk scenarios, 4-meter-high+5mm steel wire+double coating is recommended, and in low-risk scenarios, 2-3-meter+3-4mm steel wire+single coating can be selected).


Maintenance and lifespan:


Daily maintenance only requires rinsing with clean water, and coating damage can be partially repaired, significantly extending the overall lifespan;


Combining electronic fence alarm system to achieve dual protection of physical and technical protection.

Deep analysis of technical parameters


Material technology: Low carbon steel wire is cold drawn to balance strength and ductility; Laser cutting ensures grid accuracy (76mm × 12mm), minimal error, and excellent flatness.


Coating system: combination process of galvanizing, dipping and spraying, optional PVDF fluorocarbon coating, suitable for different environmental corrosion requirements.



Global case validation



Verified by over 3000 major projects worldwide, from extreme cold bases in Alaska to desert prisons in the Middle East, from Nordic data centers to Southeast Asian port facilities, we have built impeccable security defenses with rigorous process standards.


summary



Choosing the 358 anti climbing fence means choosing a mature protection solution that has been validated in global high security scenarios. Through comprehensive customization of size, color, and installation methods, it can accurately adapt to the needs of multiple scenarios such as military, judicial, energy, transportation, and high-end property, achieving professional level security protection. If you need to customize an exclusive protection plan, you can optimize the specification configuration and installation plan based on specific scenario risk assessment.

FAQS:

Q1: What is the meaning of the name?

Horizontal spacing of 3 inches (76mm), vertical spacing of 0.5 inches (12mm), and No. 8 steel wire (4mm) form a high-density anti climbing grid.



Q2: Anti climbing principle?

The fine mesh prevents grasping, the thick steel wire is resistant to cutting, and the top can be equipped with anti climbing/blade piercing ropes, providing triple protection against intrusion.



Q3: Applicable scenarios?

High security places such as military bases, prisons, and nuclear power plants; More resistant to climbing than peach shaped fences, but at a higher cost.



Q4: How long can it be used?

Galvanized+dip coated, salt spray test for over 1000 hours without rusting; PVDF coating for coastal environments, with a lifespan of 25 years.



Q5: Size and installation?

Customizable height of 1.5-4 meters, standard board width of 2-3 meters; Modular installation, daily installation of 200 meters, recommended bolt+welding fixation.



Q6: Color selection?

Standard colors such as dark green, gray white, etc. can be customized with camouflage or corporate colors; Use dark colors for concealed scenes and bright colors for identification scenes.



Q7: Maintenance costs?

Rinse with clean water, inspect the coating every six months, repair any damages, and have low long-term costs.



Q8: How to choose specifications?

Select a high-risk scenario with a height of 4 meters, 5mm thick wire, and double coating; Low risk selection of 2-3 meters+3-4mm wire+single coating requires professional evaluation.
