2D FENCE PANELS

2D Fence Panels — Flat Double Wire Welded Mesh for High-Security Fencing

2D fence panels from ULAMEX are flat welded mesh fence panels constructed with a twin horizontal wire arrangement that delivers exceptional rigidity and anti-climb performance without the V-bends found in 3D panels. Also known as double wire panels or twin wire panels, these galvanized fence panels achieve their structural strength through heavier wire gauges arranged in a distinctive sandwich configuration — two horizontal wires welded on either side of each vertical wire at every intersection point.

The flat, uniform surface of 2D panels provides significantly fewer handholds and footholds compared to 3D panels, making them the preferred specification for security fence galvanized applications where anti-climb performance is a primary requirement. This characteristic, combined with the superior resistance to cutting offered by heavier wire gauges, has established 2D panels as the standard for prison perimeters, military installations, data centres, power stations and other high-security sites across Europe.

As a specialist steel fence wholesale supplier, ULAMEX stocks 2D fence panels in both standard configurations (6/5/6 and 8/6/8) across the full height range, ready for immediate dispatch to fence contractors, security integrators and construction companies throughout the EU market.

Wire Configurations: 6/5/6 and 8/6/8

The numerical designation of 2D panels describes the wire diameter arrangement in the format: horizontal wire / vertical wire / horizontal wire. Two standard configurations cover virtually all application requirements:

6/5/6 Configuration:

• Horizontal wires: 2 × 6 mm diameter (one each side of vertical wires)
• Vertical wires: 5 mm diameter
• Application: Commercial and standard industrial fencing — the most widely specified 2D panel
• Provides excellent rigidity while remaining cost-effective for large perimeters

8/6/8 Configuration:

• Horizontal wires: 2 × 8 mm diameter
• Vertical wires: 6 mm diameter
• Application: High-security and heavy-duty perimeters — maximum cut resistance and impact strength
• The heaviest standard 2D panel, suitable for critical infrastructure and sites with elevated security requirements

Why Choose 2D Over 3D Fence Panels?

The choice between 2D and 3D fence panels depends on the specific security and aesthetic requirements of each project. 2D panels offer distinct advantages in four areas:

1. Anti-climb performance: The flat surface eliminates the horizontal ledges created by V-bends in 3D panels. Without these footholds, climbing is significantly more difficult, which is why security specifications almost universally require 2D panels for perimeters above security level 2.
2. Cut resistance: The 8/6/8 configuration places 8 mm horizontal wires on both sides of each vertical — three wires must be cut at each point to create an opening. This takes significantly longer and requires heavier tools than cutting through a single 4 mm or 5 mm wire in a 3D panel.
3. Visual uniformity: The flat profile creates a clean, uniform appearance that many architects and property developers prefer for contemporary commercial and institutional buildings.
4. Noise barrier compatibility: The flat surface provides a better mounting substrate for acoustic infill panels in noise barrier applications along motorways, railways and industrial sites.

For standard residential and light commercial applications where cost-effectiveness is the priority, 3D panels typically offer better value due to lower wire consumption per panel. For security-critical applications, 2D panels are the correct specification.

Surface Treatment and Colour Options

Every 2D panel undergoes hot-dip galvanizing per EN ISO 1461 as the base corrosion protection layer. The galvanizing process ensures complete zinc coverage of all wire surfaces, including the critical double-wire sandwich zones where the horizontal and vertical wires meet — areas particularly vulnerable to crevice corrosion if left unprotected.

For colour-matched installations, the duplex finish (galvanized + polyester powder coating) is available in:

• RAL 6005 — Moss Green
• RAL 7016 — Anthracite Grey
• RAL 9005 — Jet Black
• Custom RAL colours for wholesale quantities on request

Applications

Industrial fence galvanized 2D panels are specified for the most demanding perimeter security applications:

• High-security perimeters — prisons, military bases, government facilities, data centres
• Critical infrastructure — power stations, substations, water treatment works, telecommunications
• Industrial sites — chemical plants, refineries, manufacturing facilities, waste processing
• Anti-climb zones — restricted areas, airfields, railway corridors
• Commercial properties — corporate headquarters, hospitals, universities requiring enhanced security
• Sports facilities — ball courts, multi-use games areas (MUGAs), stadia perimeters
• Noise barriers — motorway boundaries, railway embankments, industrial boundary walls (with acoustic infill)
• Residential developments — gated communities, apartment complexes requiring flat-panel aesthetics

Installation

2D panels mount to galvanized fence posts using the same clamp system as 3D panels. Due to the heavier weight of 2D panels (especially in 8/6/8 configuration), 80×60 mm posts are recommended for panel heights above 1,630 mm to ensure adequate lateral stability. Post spacing remains at the standard 2,500 mm centre-to-centre.

For high-security installations, anti-tamper fixings with security head profiles (requiring specialist tooling for removal) are strongly recommended. ULAMEX supplies complete fixing kits matched to your panel and post specification.

Frequently Asked Questions

Are 2D panels stronger than 3D panels?
In terms of cut resistance and anti-climb performance, yes. An 8/6/8 panel uses significantly more steel per square metre than a 5 mm 3D panel. However, for general-purpose fencing where cut resistance is not the primary concern, 3D panels offer excellent performance at a lower cost point.

Can 2D and 3D panels be mixed in the same fence run?
Yes. Both panel types use the same 50×200 mm mesh spacing and mount to the same posts with the same clamps. It is common to use 2D panels in high-visibility or high-risk sections and 3D panels for standard boundary runs to optimise the project budget.

What is the maximum height available?
Standard 2D panels are available up to 2,430 mm. For higher security requirements, panels can be stacked or combined with barbed wire/razor wire extensions. Contact our team for bespoke solutions.

How do I specify 2D panels for a security project?
Provide the required panel height, wire configuration (6/5/6 or 8/6/8), total fence length, number of access points and any specific security certifications required. Our technical team will design the complete system. Request a consultation.
