358 mesh sheets provide high-security perimeter protection through narrow welded openings, rigid steel construction, and excellent surveillance visibility. BMP manufactures security mesh panels for industrial compounds, airports, bridges, utilities, and controlled infrastructure. The dense wire pattern restricts ordinary climbing attempts and complicates access for many conventional cutting tools. Customers can select flat 2D panels, 3D V-bend designs, compatible posts, and protective surface finishes.
Security fencing must meet several objectives beyond creating a physical boundary. Facility managers need reliable access control, clear sightlines, durable materials, and manageable maintenance costs. Narrow-aperture welded steel helps balance these priorities without creating a solid visual barrier. Different panel designs also support particular engineering and architectural requirements.
BMP supplies 358 mesh sheets with multiple dimensions, post configurations, and security accessories. Our product range includes flat welded panels and selected V-bend alternatives. Project teams can choose suitable designs according to site conditions, installation drawings, and expected security performance.
358 mesh sheets consist of closely spaced horizontal and vertical steel wires welded at their intersections. The designation originates from three inches, half an inch, and eight-gauge wire. These traditional measurements correspond approximately to 76.2 × 12.7 mm centres and 4 mm wire diameter.
The narrow mesh pattern creates limited space for ordinary fingers and footwear. Unlike flexible chain-link material, welded panels maintain a rigid rectangular structure. Steel posts and compatible fasteners support the sheets along the security perimeter.
Security professionals often describe this system as prison mesh. However, its applications extend beyond correctional facilities. Industrial plants, transport infrastructure, commercial compounds, and utility operators also use similar welded security panels.
Manufacturers usually describe mesh dimensions using centre-to-centre wire spacing. The actual clear opening becomes smaller after accounting for wire diameter. With 4 mm wires, the approximate opening measures 72.2 × 8.7 mm.
This distinction matters during technical inspection. Buyers should identify whether specifications describe wire centres or clear openings. Manufacturing tolerances can also influence the finished measurements.
Climbing generally requires suitable handholds and footholds. Narrow horizontal openings restrict these opportunities. The geometry creates greater climbing difficulty than many conventional wide-aperture designs.
However, no physical security fence guarantees complete intrusion prevention. Gates, nearby structures, and operational procedures can introduce additional vulnerabilities. A complete risk assessment should address these factors.
358 mesh sheets combine welded steel strength with a relatively open appearance. The compact openings support surveillance visibility without creating an opaque perimeter wall. BMP offers different configurations for various security environments.

Flat panels provide a consistent surface without pronounced horizontal bends. Their regular structure supports straightforward alignment with suitable posts. Security contractors can use full-height clamp bars or approved brackets.
Taller configurations demand careful engineering. Greater panel height increases structural loads and handling requirements. Appropriate foundations and supporting sections remain essential.
Two-metre configurations may suit selected commercial boundaries. Taller panels can support facilities with greater access-control requirements. Security assessments should determine the appropriate height.
Projects above three metres require particular attention to wind loads and construction equipment. Engineers should approve the complete system before production.
358 mesh sheets with 3D profiles introduce horizontal V-shaped bends into the welded structure. These formed sections create additional geometric depth. They can improve stiffness under suitable loading conditions.
Architectural projects may also prefer the profiled appearance. Manufacturers must confirm the relationship between wire diameter, bend geometry, and fastening arrangements.
| Item | Fence Height | Panel Size (H × W mm) | V-Bends | Post Length | Reference Sections | Intermediate Clamps | Corner Clamps |
|---|---|---|---|---|---|---|---|
| BMP-1 | 2.0 m | 2000 × 2515 | 2 | 2700 mm | RHS 80 × 60 × 2.0 / SHS 80 × 80 × 2.5 | 6 | 12 |
| BMP-2 | 2.4 m | 2400 × 2515 | 3 | 3100 mm | RHS 80 × 60 × 2.0 / SHS 80 × 80 × 2.5 | 7 | 14 |
| BMP-3 | 3.0 m | 3000 × 2515 | 3 | 3800 mm | SHS 80 × 80 × 2.5 | 10 | 20 |
RHS refers to rectangular hollow sections, while SHS identifies square hollow sections. The reference dimensions do not establish universal post compatibility. Final drawings must specify the actual structural and fastening components.
Horizontal bends create a profiled structure that differs from flat welded mesh. The additional depth can influence panel stiffness. Actual mechanical performance depends on wire specifications and bend geometry.
Buyers should request the required number of bends and their positions. Manufacturing drawings help confirm dimensional accuracy before production.
V-shaped profiles provide a distinctive visual character. The mesh still maintains relatively clear sightlines across the perimeter. Camera placement should account for the panel profile.
Commercial facilities sometimes prefer this architectural appearance. High-risk applications still require a complete structural and security assessment.
358 mesh sheets can serve different construction objectives depending on their panel geometry. Flat 2D models emphasize a uniform security surface. Profiled 3D versions introduce V-bends for alternative stiffness and appearance characteristics.
