When a project calls for welded steel mesh outside the usual reinforcing mesh specifications, Specimesh provides a practical and adaptable solution.
Vulcania Reinforcing Solutions supplies Specimesh panels in different wire diameters, aperture configurations and finishes for applications ranging from industrial partitions and machine guarding to shelving, screening and fabricated steel products.
Specimesh is also used in Vulcania’s wire mesh cable tray range, providing an open steel cable management solution for commercial, industrial and infrastructure installations.
This guide explains what Specimesh is, the standard sizes available from Vulcania, common applications, what to consider when choosing welded mesh and how Specimesh technology is used in cable tray systems.
What Is Specimesh?
Specimesh is a welded steel mesh manufactured by welding wires together at each intersection to create a rigid and consistent grid.
Unlike standard reinforcing mesh, which is primarily manufactured around established concrete reinforcement specifications, Specimesh offers greater flexibility in wire diameter, aperture and finish.
Vulcania’s Specimesh range includes panels manufactured in a selection of standard configurations, while other requirements may be available depending on manufacturing capability, quantities and project specifications.
Available finishes can include:
- Black wire
- Light galvanised
- Heavy galvanised
- Stainless steel
Specimesh panels are flush cut around the edges, removing projecting wire ends and creating a cleaner finished panel for handling, fabrication and installation.
Specimesh vs Reinforcing Mesh
Although both products consist of welded steel wire, Specimesh and reinforcing mesh are generally selected for different applications.
Reinforcing mesh is primarily used as reinforcement within concrete slabs, floors, foundations, driveways and other concrete construction.
Specimesh is better suited to applications where aperture size, wire diameter, panel configuration, visibility, ventilation or fabrication requirements determine the choice of mesh.
Typical Specimesh applications include:
- Industrial partitions
- Machine guards and safety screens
- Storage cages
- Shelving and bins
- Display systems
- Balustrade infill
- Security screening
- Fabricated steel products
- Selected light-duty reinforcement applications
- Cable management systems
For structural concrete applications, the correct reinforcement should always be selected according to the engineer’s drawings and project specifications.
If your application is concrete reinforcement rather than screening or fabrication, explore Vulcania’s broader mesh and reinforcing mesh range.
Standard Vulcania Specimesh Panel Sizes
Vulcania’s standard Specimesh panels are available in a range of wire diameters and apertures to suit different applications.
Standard 2400 mm x 1200 mm panel configurations include:
| Wire Diameter | Aperture | Approx. Panel Weight |
|---|---|---|
| 3.15 mm | 50 x 50 mm | 7.20 kg |
| 3.15 mm | 25 x 50 mm | 11.40 kg |
| 4 mm | 50 x 50 mm | 12.00 kg |
| 4 mm | 25 x 50 mm | 18.00 kg |
| 5 mm | 50 x 50 mm | 18.00 kg |
| 5 mm | 25 x 50 mm | 27.00 kg |
These configurations allow buyers to choose between different levels of openness, rigidity and panel weight rather than forcing every application into one standard welded mesh configuration.
Current options and availability can be viewed on the Vulcania Specimesh panels product page.
For larger projects or technical procurement, Vulcania also provides product catalogues and supporting documents through its Download Centre.
How Do You Choose the Right Specimesh?
There is no single Specimesh configuration that is suitable for every application.
The right choice starts with understanding what the mesh needs to do.
1. Start With the Application
Determine whether the mesh will be used for:
- Screening
- Guarding
- Partitioning
- Storage
- Fabrication
- Architectural applications
- Light reinforcement
- Cable management
- Another industrial purpose
A machine guard has very different requirements from a retail display, just as a warehouse partition has different requirements from an architectural screen.
2. Consider the Aperture Size
The aperture is the open space between the wires.
A smaller aperture creates closer spacing, while a larger aperture provides a more open panel.
The appropriate aperture will depend on factors such as:
- Visibility requirements
- Accessibility
- Safety
- The size of objects being contained or excluded
- Airflow
- The overall purpose of the installation
3. Consider the Wire Diameter
Increasing the wire diameter generally creates a heavier and more rigid panel.
That does not automatically mean the heaviest available Specimesh is the best option.
The wire diameter should suit the actual application, frame construction, loading and installation requirements.
4. Consider the Environment
An indoor warehouse installation and an exposed outdoor installation may require very different corrosion protection.
The required finish should therefore be considered alongside the mesh configuration, particularly for:
- Coastal environments
- High-moisture areas
- Outdoor installations
- Industrial environments
- Corrosive operating conditions
5. Consider Fabrication and Installation
Panel dimensions, framing, fixing methods, support structures, transport and handling should all be considered before material is ordered.
For larger or unusual requirements, speak to Vulcania before finalising the specification so that manufacturing capability, stock availability and lead times can be confirmed.
Specimesh for Machine Guards and Safety Screens
Machine guarding is one of the industrial applications where welded mesh can be particularly useful.
The open construction of Specimesh can create physical separation from moving equipment while allowing operators and maintenance teams to maintain visibility of the machinery behind the barrier.
In South Africa, machine guarding forms part of workplace health and safety requirements. The Driven Machinery Regulations under the Occupational Health and Safety Act address the guarding of dangerous machinery and moving components.
Installing a mesh panel alone does not automatically make a machine guard compliant.
The complete system should consider:
- Aperture size
- Distance from the hazard
- Guard height
- Framing
- Fixings
- Access points
- Moving components
- The specific machinery being protected
Where machinery safety is involved, the guarding system should be assessed and designed according to the equipment and applicable safety requirements.
Industrial Partitions and Storage Cages
Warehouses, factories, workshops and distribution facilities often need areas to be separated without constructing permanent solid walls.
Specimesh can be incorporated into fabricated steel frames to create:
- Stock cages
- Tool stores
- Equipment enclosures
- Warehouse partitions
- Restricted-access areas
- Material storage areas
- Security enclosures
The open structure maintains visibility and airflow while creating a clear physical separation between working or storage areas.
For contractors and fabricators, Specimesh therefore offers value as a versatile steel component rather than only as a finished mesh product.
Shelving, Displays and Fabricated Products
Welded steel mesh is also well suited to storage, display and fabrication applications.
Potential uses include:
- Shelving
- Retail displays
- Storage bins
- Racking components
- Equipment screens
- Workshop storage
- Industrial baskets
- Custom fabricated steel products
The appropriate Specimesh configuration will depend on the intended load, aperture requirement, support structure and frame design.
Balustrades and Architectural Screens
The uniform grid of welded steel mesh can create a clean industrial appearance, making Specimesh suitable for selected architectural screens, partitions and balustrade infill applications.
Where mesh is incorporated into a balustrade, barrier or fall-protection system, the complete assembly must meet the applicable structural and safety requirements.
Specimesh should therefore be considered as one component of the finished system rather than assuming the mesh panel alone determines compliance.
Can Specimesh Be Used for Concrete Reinforcement?
Selected welded steel mesh products may be used in lighter pavement, pathway and landscaping applications where reinforcement is required.
However, Specimesh should not automatically be substituted for engineered reinforcing mesh in structural concrete applications.
Where concrete forms part of a structural slab, foundation, roadway or engineered structure, the reinforcement must be selected according to the engineer’s design and project requirements.
Vulcania supplies a comprehensive mesh product range for reinforcement, industrial, construction and fencing applications.
Specimesh Cable Trays
One of the most practical applications of welded wire technology is cable management.
Vulcania manufactures Specimesh cable trays using welded steel wire in a range of widths for electrical, data and communication cable installations.
The open mesh construction provides a defined route for cables while keeping the installation accessible for inspection, maintenance and future modifications.

What Should Be Considered When Selecting a Cable Tray?
Cable tray selection should not be based on width alone.
The complete installation should consider several factors.
Cable Quantity and Size
The tray should provide sufficient capacity for the intended cable installation while allowing for the requirements of the electrical design and possible future expansion.
Cable Load
The total weight of installed cables needs to be considered together with the tray and its supporting structure.
Support Spacing
The distance between supports can influence the performance of the installed cable tray system.
Installation Environment
Indoor, outdoor, industrial and potentially corrosive environments can require different materials, coatings or corrosion protection.
Cable Segregation
Electrical power, communication, instrumentation and other cable systems may have specific separation or segregation requirements.
Accessibility
Future inspections, maintenance and additional cable installation should be considered when planning cable routes.
Internationally, IEC 61537:2023 specifies requirements and tests for cable tray systems and cable ladder systems intended to support and accommodate cables in electrical and communication installations.
Project engineers and electrical professionals should confirm which standards, load requirements and installation specifications apply to each individual project.
Why Use an Open Wire Mesh Cable Tray?
Wire mesh cable trays provide several practical benefits depending on the application.
Cable Organisation
Cable trays provide defined routes for cables and can help maintain an organised installation across factories, commercial buildings and industrial facilities.
Accessibility
The open mesh structure makes installed cables visible and accessible for inspection, maintenance and future modifications.
Airflow
The open design allows air movement around installed cables, although electrical loading and temperature requirements still need to be considered as part of the electrical design.
Flexible Routing
A range of tray widths allows the cable management system to be selected according to the scale of the installation.
Future Expansion
Where planned correctly, accessible cable tray systems can make future cable additions or changes easier than fully enclosed systems.
