358 anti-climb welded mesh provides reliable perimeter protection for prisons, airports, military facilities, factories, and critical infrastructure. BMP manufactures high-security welded wire fencing with narrow openings, strong welded intersections, and durable protective finishes. This design helps discourage climbing, cutting, and unauthorized entry while maintaining excellent visibility.
Commonly known as prison mesh or 358 security fencing, this system combines rigid steel panels with heavy-duty posts and secure fastening components. The name 358 originates from its nominal 3-inch by 0.5-inch mesh spacing and 8-gauge wire specification. Buyers can select different panel heights, post dimensions, coatings, and installation accessories to suit their security requirements.

358 anti-climb welded mesh consists of horizontal and vertical steel wires welded together at every intersection. Its closely spaced horizontal wires create openings that offer limited finger and footholds. This construction makes climbing considerably more difficult than with conventional chain-link fencing.
The standard nominal mesh spacing measures 76.2 × 12.7 mm from wire centre to wire centre. Actual clear openings are smaller because the wire diameter occupies part of the spacing. For example, a 4 mm wire produces approximate clear openings of 72.2 × 8.7 mm.
Unlike conventional wide-aperture welded mesh, the narrow configuration restricts access for many common cutting tools. However, actual resistance depends on wire diameter, welding quality, attachment design, and the tools used during an attack.
For projects requiring high visibility, BMP also supplies ClearVu fence panels with alternative mesh configurations. Project engineers can compare both systems before finalizing perimeter specifications.
BMP offers 358 anti-climb welded mesh in multiple panel heights and structural configurations. The following reference specifications include panel dimensions, matching posts, clamp bars, and fastening quantities.

These dimensions represent available reference configurations rather than universal installation requirements. Final post sections, embedment depths, and fixing quantities require project-specific structural verification.
Buyers should confirm whether their specified mesh measurements represent centre-to-centre spacing or clear openings. This distinction affects both technical compliance and security performance.
358 anti-climb welded mesh restricts potential handholds and footholds through its narrow rectangular apertures. Unlike conventional fencing, its geometry offers limited opportunities for climbing without specialized equipment. Additional security measures can strengthen the overall perimeter.
Each welded intersection contributes to panel rigidity and helps maintain the original mesh geometry. Strong wires also increase the effort required for cutting. For higher-risk sites, designers should assess the complete fencing assembly rather than individual panels alone.
Security personnel can observe activity through the narrow mesh openings. This visibility supports camera coverage, patrol operations, and routine perimeter inspections. Proper camera positioning remains important because any fencing mesh can affect viewing angles.
Protective zinc coatings help reduce steel corrosion. An additional powder-coated finish can provide decorative color and another protective barrier. Coating selection should reflect environmental exposure, especially in coastal and industrial locations.
358 mesh can form part of a larger perimeter security system. Compatible options include anti-tamper fasteners, controlled-access gates, alarm equipment, and approved topping arrangements. Each accessory requires suitable engineering and local compliance checks.
358 mesh suits facilities where security, durability, and visibility are important. South African applications range from industrial compounds to critical utility infrastructure.
Correctional facilities require strong perimeter barriers and carefully managed access points. Narrow welded mesh helps discourage climbing and unauthorized movement. Project specifications may also require additional detection systems, controlled gates, and secure foundations.
Airport perimeter fencing helps define restricted operational areas. Security designers must consider visibility, intrusion resistance, service access, and applicable aviation requirements. Fence heights and accessory arrangements should follow the facility's approved security plan.
Mining operations often protect machinery, storage yards, and restricted production areas. Strong perimeter fencing helps establish controlled boundaries. For projects in Limpopo, Gauteng, and other mining regions, foundation design should account for local ground conditions.
Electrical substations, water treatment facilities, and communication installations need controlled access. 358 anti-climb welded mesh helps separate public areas from restricted equipment. Appropriate warning signs, earthing considerations, and safety clearances remain essential.
Commercial operators can combine security fencing with surveillance and access-control systems. Clear sightlines assist security teams without creating a solid visual obstruction. Fence selection should reflect property risk, traffic movement, and operational needs.
Selected school and recreational sites may benefit from secure perimeter boundaries. However, installations must consider child safety, emergency access, and the suitability of security accessories. High-risk prison-style toppings are not appropriate for every public environment.

358 anti-climb welded mesh requires appropriate corrosion protection for its operating environment. BMP offers several finish options according to project requirements.
Hot-dip galvanizing creates a protective zinc coating on steel surfaces. Galvanizing completed after fabrication can protect welded intersections and exposed steel surfaces. Buyers should specify coating requirements, including applicable standards such as ISO 1461 where appropriate.
A duplex finish combines zinc corrosion protection with a decorative powder coating. Correct surface preparation is essential for adhesion and coating durability. Customers should identify their preferred RAL color and environmental exposure classification.
PVC-coated configurations provide an alternative protective and decorative surface. Material compatibility, coating thickness, and expected service conditions should be agreed upon before production.
358 anti-climb welded mesh can be supplied in various RAL colors. Popular selections include RAL 6005 Moss Green, RAL 9005 Jet Black, and RAL 7016 Anthracite Grey. Custom colors are available subject to coating material availability and order requirements.

358 mesh installation requires accurate setting-out, properly designed foundations, and secure panel connections. Qualified installers should follow the approved project drawings and site safety requirements.
Measure the complete perimeter and identify corners, changes in elevation, drainage routes, and gate locations. Check underground services before excavation. Confirm property boundaries and any applicable local restrictions.
Mark the post centres according to the approved panel and fastening configuration. A nominal 2515 mm panel width does not automatically establish the correct post spacing. Allow for clamp geometry and manufacturer tolerances.
Excavate foundation holes according to the structural design. Soil bearing capacity, fence height, wind loading, and security requirements determine the necessary foundation dimensions. Taller fences may require substantially larger foundations.
Install posts vertically and maintain the specified alignment. Check heights and levels before the foundations reach their required strength. Temporary bracing may be necessary during construction.
Position each panel against its supporting posts and install the specified clamp bars or brackets. Use suitable security fasteners and tighten them according to the manufacturer's instructions. Avoid damaging protective coatings during installation.
Examine panel alignment, fixing security, gate operation, and coating condition. Repair any damaged protective surfaces using the approved repair method. Record installation checks before project handover.
For additional planning information, consult our ClearVu fence installation guide. Although the products differ, many basic site-planning principles remain relevant.

358 anti-climb welded mesh pricing depends on material consumption, manufacturing specifications, finishing requirements, and shipping conditions. A reliable quotation should clearly distinguish the panel-only price from the complete fencing system cost.
Thicker steel wire generally increases panel weight and material cost. Buyers should compare equivalent wire diameters rather than selecting products solely by panel dimensions.
Taller panels may require larger posts, stronger clamp bars, and more substantial foundations. These components can materially influence total project expenditure.
Galvanizing, powder coating, and PVC coating have different processing requirements. Coating thickness, preparation, and project color selection affect manufacturing costs.
Production volume, packing efficiency, container utilization, and destination port influence delivered pricing. South African buyers should consider customs clearance, inland transport, and installation separately.
