358 Anti‑Climb Security Mesh Fence Panels

These panels are formed from high‑tensile steel wire welded into a uniform 3 mm × 3 mm square mesh, then hot‑dip galvanized to a minimum coating weight of 275 g/m². The resulting barrier resists cutting, climbing, and corrosion while maintaining a clear sight line for surveillance.

Design and Construction

Wire diameter: 3.0 mm (±0.05 mm) cold‑drawn steel.
Mesh opening: 3 mm × 3 mm, providing a rigid anti‑climb geometry.
Panel dimensions: standard width 2.5 m, height options 2.0 m, 2.4 m, 3.0 m.
Edge finishing: flattened and capped with a 20 mm × 20 mm steel strip to eliminate sharp protrusions.
Coating: hot‑dip galvanized per ASTM A123, with optional polyester powder coat for additional UV resistance.

Technical Specifications

Parameter	Typical Value
Tensile strength of wire	≥ 550 MPa
Elongation at break	≥ 10 %
Mesh opening size	3 mm × 3 mm
Coating thickness (galvanized)	≥ 55 µm (≈275 g/m²)
Wind load resistance (per EN 1991‑1‑4)	Up to 2.5 kPa (depends on post spacing)

Applications

The 3 mm mesh creates a surface that is difficult to grasp or scale, making the panels suitable for high‑security perimeters such as correctional facilities, military installations, and critical infrastructure sites. Their open design allows CCTV cameras and motion sensors to maintain unobstructed lines of sight, reducing blind spots that solid barriers can create.

In commercial environments like data centers and power substations, the panels deter unauthorized access while preserving airflow and light transmission, which helps maintain equipment cooling and reduces the need for additional lighting fixtures.

Material Options

Base material is low‑carbon steel with a controlled carbon content of 0.12 % to 0.20 % to ensure weldability and ductility. For environments with elevated chloride exposure, a zinc‑aluminium alloy coating (Zn‑Al 5 %) can be specified, offering improved corrosion resistance compared to standard galvanizing.

Standard hot‑dip galvanized (Zn 99 %).
Zinc‑aluminium alloy coating (Zn‑Al 5 %).
Polyester powder coat over galvanized layer (RAL colors available).

Customization

Panel width can be adjusted in 0.5 m increments to match site‑specific post spacing, while height can be tailored from 1.8 m up to 4.0 m without compromising mesh integrity. Additional features such as integrated anti‑cut barbs, tension wire grooves, or pre‑drilled mounting plates are available upon request.

Quality Control

Each production batch undergoes tensile testing of wire samples, coating thickness measurement via magnetic induction, and visual inspection of weld consistency. Panels are checked for dimensional accuracy (±5 mm) and surface defects before packaging. Test reports are retained for traceability and can be supplied with the shipment.

Packaging and Shipping

Panels are stacked flat on pallets, separated by corrugated cardboard layers, and secured with steel straps. For overseas shipments, moisture‑barrier film and corner protectors are added to prevent corrosion during transit. Standard pallet size accommodates up to 20 panels, facilitating efficient handling with forklifts.
