Double Wire Fence (2D Fence): Specifications, 656 vs 868 and Applications
Double wire fencing, also known as 2D fencing or double horizontal wire fencing, is widely used for industrial, commercial, educational and public perimeter applications.
Its distinctive welded mesh construction combines two horizontal wires with one vertical wire at each crossing, creating a rigid panel with a flat, modern appearance.
Compared with many conventional single-wire welded mesh panels, double wire fencing can offer greater panel stiffness when the wire dimensions and other design conditions are comparable.
BenDin manufactures customizable double wire fence systems for international contractors, distributors and project buyers.
This guide explains common 656 and 868 configurations, panel dimensions, coatings, posts, installation options and purchasing considerations.
What Is a Double Wire Fence?
A double wire fence is a welded steel mesh fencing system featuring two horizontal wires positioned on opposite sides of a single vertical wire.
The wires are welded together to form a rigid panel.
Unlike 3D V-bend fencing, which uses reinforcement bends, double wire fence panels generally have a flat profile.
The design is commonly selected for projects requiring:
- Rigid welded mesh panels
- Clear perimeter visibility
- Modern architectural appearance
- Modular installation
- Customizable heights and finishes
- Compatible gates and posts
The final strength of the fencing system depends on the complete design, including wire sizes, panel dimensions, posts, fixings and foundations.
656 vs 868 Double Wire Fence
Two widely recognized double wire fence configurations are 656 and 868.
These numbers refer to the nominal diameters of the horizontal and vertical steel wires.
656 Double Wire Fence
A 656 fence typically uses:
- Two horizontal wires: 6 mm each
- One vertical wire: 5 mm
This configuration offers a balance between rigidity, material usage and project cost.
868 Double Wire Fence
An 868 fence typically uses:
- Two horizontal wires: 8 mm each
- One vertical wire: 6 mm
The larger wire diameters generally produce a heavier and more rigid panel than an otherwise comparable 656 configuration.
656 vs 868 Comparison
| Feature | 656 Fence | 868 Fence |
|---|---|---|
| Horizontal Wires | 2 × 6 mm | 2 × 8 mm |
| Vertical Wire | 5 mm | 6 mm |
| Panel Weight | Generally Lower | Generally Higher |
| Panel Rigidity | Moderate to High | Generally Higher |
| Material Cost | Generally Lower | Generally Higher |
| Typical Applications | Schools, Residential, Commercial | Industrial, Logistics, Demanding Perimeters |
Actual performance depends on panel dimensions, mesh geometry, material properties and installation details.

Why Double Horizontal Wires Improve Rigidity
The double horizontal wire structure is the main feature of 2D fencing.
At each welded crossing, the vertical wire is connected to two horizontal wires.
This arrangement increases the amount of steel in the horizontal direction and can improve resistance to panel deformation compared with a similarly sized single-horizontal-wire design.
However, higher rigidity does not automatically make a fence suitable for all high-security applications.
Projects requiring certified resistance to climbing, cutting or forced entry should specify and evaluate an appropriate complete security system.
Surface Treatment Options
Double wire fencing is commonly installed outdoors, making corrosion protection an important purchasing consideration.
Hot-Dip Galvanizing
Galvanizing provides a protective zinc coating on steel.
The galvanizing process and coating requirements should be confirmed according to the project specification.
Powder Coating
Powder coating provides a decorative colored finish.
Polyester powder coatings are commonly considered for outdoor steel fencing.
Galvanized and Powder-Coated Finish
A combined galvanized and powder-coated system can provide corrosion protection together with a selected architectural color.
The performance of any coating system depends on surface preparation, coating specifications and environmental exposure.
Choosing Posts for Double Wire Fence
A double wire fence panel must be supported by appropriately selected posts and connections.
Common options include:
Square Posts: Suitable for many commercial and industrial installations.
Rectangular Posts: May be selected according to structural or connection requirements.
Round Posts: Used where compatible fittings and post designs are specified.
Profiled Posts: Specialized profiles may be available for particular fence systems.
Post dimensions, wall thickness, spacing and foundations should be determined according to the fence height, site conditions and applicable design loads.
Double Wire Fence Applications
Schools and Educational Facilities
Double wire fencing provides clear boundaries while maintaining visibility.
Panel openings, fence height, gates and other details should be selected according to the facility’s safety requirements.
Industrial Parks
Industrial sites often require rigid fencing for perimeter separation and access control.
Double wire fencing can be combined with matching gates and controlled entry points.
Logistics Centers
Logistics facilities may use double wire fencing to separate site boundaries, parking areas and restricted zones.
Where vehicle impacts are a concern, separate engineered impact protection may be necessary.
Residential Communities
The flat mesh appearance and available RAL colors make double wire fencing suitable for selected residential developments.
Sports Facilities
Double wire fencing can be considered for certain sports facility boundaries.
The required height, mesh dimensions and structural performance depend on the activity.
Example: 600-Meter Logistics Facility Fence
Consider a logistics facility requiring approximately 600 meters of perimeter fencing.
A preliminary project specification might include:
| Item | Example Requirement |
|---|---|
| Total Fence Length | 600 m |
| Fence Type | 868 Double Wire Fence |
| Fence Height | 2,030 mm |
| Panel Width | 2,500 mm |
| Mesh Opening | 50×200 mm |
| Surface Treatment | Galvanized + Powder Coated |
| Color | RAL 7016 Anthracite Grey |
| Posts | Square Steel Posts |
| Gates | According to Site Layout |
Using nominal 2.5-meter panel sections:
600 ÷ 2.5 = approximately 240 panels.
The final quantity of panels, posts, clamps and foundations depends on gates, corners and the actual site dimensions.
This is an illustrative procurement example, not a claimed completed BenDin customer project.
Double Wire Fence vs 3D Fence
Both double wire and 3D welded mesh fencing are used for perimeter applications, but their reinforcement methods differ.
| Feature | Double Wire Fence | 3D V-Bend Fence |
|---|---|---|
| Panel Profile | Flat | V-Shaped Reinforcement Bends |
| Reinforcement | Double Horizontal Wires | Formed Panel Bends |
| Common Wire Sizes | 656 / 868 | Often 4–5 mm |
| Appearance | Flat and Linear | Folded Mesh Profile |
| Typical Selection Factors | Rigidity, Flat Design | Cost, Weight, Panel Design |
Neither fence type is universally better. Selection should be based on project requirements, complete system performance and budget.
