Steel Wire Mesh Fencing (YB/T4001.1-2007): 550g/m² Zinc-Coated Anti-Climb and Anti-Cut Security Systems

In high-load security perimeters, Steel Wire Mesh Series engineering focuses on preventing unauthorized penetration through aperture control and weld-point shear resistance. Utilizing high-tensile carbon steel, these systems are categorized by their Physicochemical Parameters and resistance to mechanical breaching tools.

I. Material Engineering & Physicochemical Parameters

All panels undergo a dual-phase protection process: Hot-Dip Galvanization followed by Polyester Powder Coating (PPC) to ensure ISO-compliant corrosion resistance in C4/C5 environments.

II. Security Grade Stratification & Morphology

Selecting the optimal Morphological design is critical for balancing visibility with intrusion delay. The series is divided into four high-performance categories:

1. "358" Prison Mesh (Anti-Climb / Anti-Cut)

Features a 0.5" x 3.0" (12.7mm x 76.2mm) aperture. This tight spacing prevents footholds for climbing and ensures that manual cutting tools cannot gain leverage. Ideal for prisons, utility hubs, and military perimeters.

2. Twin-Wire Systems (Protek 656/868)

Utilizes horizontal twin wires to significantly increase Compounding Efficiency against kinetic impact. The 8/6/8mm configuration is the standard for sports stadiums and high-traffic industrial estates.

3. 3D V-Mesh Series (Structural Rigidity)

Features integrated "V" folds that provide longitudinal stiffness without the need for additional horizontal rails. This Rail-less System utilizes Spider Clamps for rapid deployment.

4. Bar Grating & Expanded Metal

• Bar Grating: Supports H-20 vehicle loading; pressure-locked intersections for fire escapes and offshore platforms.
• Expanded Metal: Slit and stretched sheets that provide high strength-to-weight ratios, ideal for ventilation enclosures and facade screens.

III. Custom Engineering & Integrated Systems

Integrated Perimeter Components

• Infini-Rail® System: Flexible bypass rail systems for variable post spacing.
• DualGuard™ Technology: Dual-layer infills that increase breach time exponentially (1 + 1 > 4 breach resistance).
• Fixing Options: Anti-tamper bolt-free connections and reinforced hinges for integrated access gates.
