In prison security systems, fencing is the most vulnerable element, yet it must be designed to be "unbreakable quickly." Many projects, when selecting anti-climb fencing, focus only on height, neglecting crucial indicators such as material strength, mesh structure, and time to breach, resulting in enormous investments.

        To truly achieve "unclimbable, difficult to breach, and controllable even after breach," prison anti-climb systems must be re-understood from three perspectives: material resistance to damage, structural anti-climb design, and the duration of protection against breaches.

        Ⅰ. Material: The foundation of durability and strength

        1. Substrate Selection: High-strength low-carbon steel wire or stainless steel (commonly 304/316) is preferred as the load-bearing wire. High-strength low-carbon steel, after hot-dip galvanizing or plastic coating, achieves a balance between strength, economy, and corrosion resistance.

        2. Surface Protection: The hot-dip galvanizing amount should meet the long-term weather resistance requirements of the project. For special environments (coastal areas, chemical corrosion), stainless steel or a secondary protection of galvanized steel + polyester powder coating is preferred.

        3. Wire Diameter and Mechanical Properties: The diameter of the main load-bearing wire should meet the tensile strength and shear resistance requirements, and tensile/fracture test reports should be provided for acceptance.

        Ⅱ. Structure: Key to preventing climbing and delaying destruction

        1. Small-mesh mesh: Dense mesh effectively eliminates hand and footholds, structurally reducing the likelihood of climbing.

        2. Double-layer/staggered structure:Double-layered mesh or staggered inner and outer arrangements increase cutting difficulty and time costs. Alarm lines or sensor cables can be installed between the two layers,creating multiple layers of protection.

        3. Edge and top design: Outward bends, angled projections, or the addition of barbed wire at the top further hinder climbing; reinforced edges ensure overall stability under stress.

        4. Base and fixing method: Posts should ideally have a thickened cross-section and be anchored to the foundation concrete. Connectors should have anti-loosening designs and bolt anti-theft measures.

        Ⅲ. Duration of protection against damage: an indicator of the value of protection

        The design of prison security fence should extend the time before damage from manual cutting or simple tools can be detected through inspection or monitoring, and ensure that the use of electric cutting tools also incurs significant time and noise costs. Therefore, the following recommendations are made:

        • Utilizing multi-layered structures and reinforced frames;

        • Increasing physical barriers (small apertures, angled tops, barbed wire) and electronic linkages (tension/cutting sensors, perimeter alarms);
