What Is Clearview Fencing?
Clearview fencing, also known as 358 mesh fencing or anti-climb fencing, is one of the most widely used high-security perimeter solutions in South Africa. The name "358" refers to its mesh dimensions: 3-inch (76.2mm) horizontal spacing, 0.5-inch (12.7mm) vertical spacing, and 8-gauge (4mm) wire diameter. This tight mesh configuration creates a fence that is virtually impossible to climb, extremely difficult to cut, and maintains clear visibility through the panel.
Originally developed for prison and military applications, clearview fencing has become the go-to choice for security fencing across Cape Town. From residential estates in Constantia and Stellenbosch to commercial warehouses in the Northern Suburbs, clearview fencing offers the perfect balance of security, aesthetics, and durability.
Unlike solid wall or palisade fencing, clearview mesh maintains full visibility of your surroundings. This aligns with Crime Prevention Through Environmental Design (CPTED) principles: it eliminates blind spots where intruders can hide, allows CCTV cameras to monitor beyond the perimeter, and gives the property an open, welcoming appearance despite offering maximum protection.
358 Mesh Specifications
Understanding the specifications of clearview fencing helps you make an informed decision. Here are the key technical details:
Standard 358 Mesh
- Horizontal wire spacing: 76.2mm (3 inches)
- Vertical wire spacing: 12.7mm (0.5 inches)
- Horizontal wire diameter: 4.0mm
- Vertical wire diameter: 3.0mm (inner wire)
- Panel width: Typically 2,515mm
- Welding: Resistance-welded at every intersection
The small aperture size (76.2mm x 12.7mm) is the key security feature. Fingers cannot grip the mesh for climbing, standard bolt cutters cannot access the wire intersections, and the panel remains rigid even under sustained attack. This is why clearview fencing is classified as a high-security perimeter solution under South African National Building Regulations.
868 Mesh (Double Wire)
A related product is 868 mesh fencing, which uses 8mm horizontal wires with 6mm verticals and an 8mm spacing pattern. While not as secure as 358, the 868 variant is popular for welded mesh applications where moderate security with a clean appearance is needed, such as school perimeters, sports facilities, and residential complexes.
Height Options
Clearview fencing is manufactured in four standard heights, each suited to different applications:
- 1.5 metres: Suitable for internal boundaries, garden dividers, and low-risk perimeters. Often used within residential complexes to separate units while maintaining sight lines.
- 1.8 metres: The most popular height for residential properties across Cape Town. Provides effective perimeter security while complying with most municipal bylaws. Ideal for homes in Somerset West, Paarl, and suburban areas.
- 2.1 metres: The standard for commercial and light industrial properties. Offers excellent security and is commonly paired with electric fencing on top for additional deterrence.
- 2.4 metres: Maximum standard height for high-security applications. Used for warehouses, distribution centres, government facilities, and properties requiring premium perimeter protection. Often combined with razor wire or electric fencing.
Pro Tip: When selecting fence height, check your local municipality's building regulations. The National Building Regulations (SANS 10400) restrict boundary fences to 1.8m in most residential areas without special permission. Our team can advise on the requirements for your specific area.
Coating Options
The coating you choose directly affects how long your clearview fence will last, especially in Cape Town's varied climate. From the salt air along the Atlantic Seaboard to the hot, dry conditions in the Winelands, the right coating is essential.
Hot-Dip Galvanised
The standard coating for clearview fencing. The entire welded panel is submerged in molten zinc, creating a protective barrier against rust and corrosion. According to the Hot Dip Galvanizers Association of Southern Africa (HDGASA), galvanised clearview fencing typically lasts 15 to 20 years in inland areas. In coastal suburbs like Bloubergstrand, Milnerton, and Strand, the salt air reduces this lifespan, making additional protection advisable.
Powder-Coated
An electrostatic powder coating is applied over the galvanised base, adding both colour and an extra layer of corrosion protection. Available in a range of colours (green and black are the most popular in Cape Town), powder coating extends the fence life by 5 to 10 years and gives a more finished, aesthetic appearance. This is the preferred option for residential and commercial properties where appearance matters.
Dual Coating (Galvanised + Powder-Coated)
The premium option combines hot-dip galvanising with a polyester powder coat finish. This dual-layer approach provides 25 to 30+ years of protection and is strongly recommended for coastal properties, swimming pool surrounds, and any installation exposed to harsh weather. The upfront cost is approximately 20% more than galvanised alone, but the extended lifespan makes it the most cost-effective option over time.
Applications
Residential
Clearview fencing has become the preferred choice for modern Cape Town homes and housing estates. Its slim profile and transparent appearance do not obstruct mountain or sea views, making it popular in suburbs like Constantia, Camps Bay, and Hout Bay. Combined with electric fencing on top, it provides comprehensive perimeter security for residential properties.
Commercial
Office parks, retail centres, warehouses, and business premises across Cape Town rely on clearview fencing for perimeter security. The visibility allows natural surveillance from the street and enables security guards and CCTV systems to monitor effectively. Many commercial properties pair clearview fencing with automated gate systems for controlled vehicle and pedestrian access.
Industrial
Factories, distribution centres, and storage facilities require robust perimeter security. The 2.4m clearview fence with razor wire or electric fencing is the standard specification for industrial installations. The anti-climb, anti-cut properties of 358 mesh make it particularly effective for protecting high-value inventory and equipment.
Public and Institutional
Schools, hospitals, government buildings, and sports facilities throughout Cape Town use clearview fencing. Its transparent design maintains a welcoming appearance while securing the premises. The inability to climb the mesh makes it especially suitable for school perimeters where child safety is a priority.

Installation Process Overview
Professional clearview fencing installation follows a proven process to ensure a secure, level, and long-lasting result. Here is what to expect when you request a quote and proceed with installation:
- Choose your specification: Select the mesh type (358 or 868), height, and coating based on your security needs and budget. Our team will recommend the best option for your property.
- Site survey and measurement: A qualified installer visits your property to measure the perimeter, assess the terrain (slope, rock, soil type), identify obstacles (trees, existing structures), and plan post positions and gate locations.
- Site preparation: Clear vegetation and debris from the fence line. Mark the boundary with string lines and pegs. Ensure vehicle access for delivery of materials.
- Post installation: Dig post holes at 2.5m to 3m intervals. Set 76mm x 76mm square steel posts in concrete footings (minimum 500mm deep). Allow concrete to cure for 24 to 48 hours before attaching panels.
- Panel attachment: Secure clearview mesh panels to posts using tamper-proof security clamps and fixings. Panels are overlapped at posts for added rigidity. Level and align each panel carefully.
- Accessories and finishing: Install gates, anti-climb brackets, electric fencing brackets, or razor wire as specified. Conduct a final inspection and hand over to the client.

What Affects the Cost
Clearview fencing is a mid-range fencing option in terms of upfront cost, offering exceptional value when you consider its 20 to 30 year lifespan and minimal maintenance requirements. Every project is priced individually, so rather than quoting numbers that may not apply to your site, here are the factors that drive the final price:
- Height: Each step up from 1.5m to 1.8m, 2.1m and 2.4m uses more steel and taller posts, which adds to the running-fence cost.
- Coating: Hot-dip galvanised is the standard finish. Adding a powder-coat layer (green, black or charcoal) adds material and processing cost but extends life in coastal conditions.
- Terrain: Level ground installs faster than sloped or rocky sites. Stepped panels, rock drilling and additional posts on slopes push the price up.
- Gates, corners and access points: Each gate, pillar and corner is a custom fabrication item, separate from the running fence rate.
- Site access: Easy vehicle access for posts, concrete and panels is cheaper than wheelbarrowing materials over long distances or through restricted gates.
- Removals and ground works: Demolishing an old fence or wall, removing rubble, and excavating footings on hard ground all add labour time.
- Accessories: Anti-climb brackets, electric-fence brackets, razor wire, anti-tamper fixings and matching gates are quoted as line items.

Maintenance Basics
One of the biggest advantages of clearview fencing is its low maintenance requirements. Unlike wooden fencing which needs regular treatment, or walls that require repainting, clearview fencing needs only basic attention to remain in excellent condition for decades.
- Monthly: Visual inspection for damage, loose fixings, or vegetation growing against the fence.
- Quarterly: Wash down with a garden hose to remove dust, bird droppings, and salt build-up (essential in coastal areas).
- Annually: Check coating condition, touch up any scratches or chips with matching paint, and tighten all fixings.
- As needed: Trim vegetation at least 300mm from the fence line to prevent moisture retention and corrosion.

How to Choose the Right Specification
Selecting the correct clearview fencing specification depends on several factors. Here is a quick decision framework:
Consider Your Security Needs
- Standard residential: 1.8m 358 mesh, galvanised or powder-coated. Pair with electric fencing for additional security.
- Estate or complex: 2.1m 358 mesh, powder-coated in green or black to blend with landscaping.
- Commercial or industrial: 2.1m to 2.4m 358 mesh with anti-climb brackets and optional razor wire.
- Moderate security (schools, parks): 1.8m to 2.1m 868 mesh, powder-coated for aesthetic appeal.
Consider Your Location
- Coastal (within 5km of the sea): Dual coating (galvanised + powder-coated) is strongly recommended to resist salt corrosion.
- Inland: Galvanised is sufficient for most applications, though powder-coating adds colour and extra protection.
- Hilly or rocky terrain: Stepped panel installation may be needed, which affects cost. Discuss with your installer during the site survey.
Consider Your Budget
While clearview fencing has a higher upfront cost than basic welded mesh or wooden fencing, its 20 to 30 year lifespan and near-zero maintenance costs make it the most economical option over time. If budget is a concern, start with galvanised panels and consider upgrading to powder-coated in the future.
